In this study, field emission AES and small-area XPS techniques were used to analyze surface composition and depth profiles on discolored bondpads to identify possible root causes for nonstick failure. In wafer fabrication, the discolored bondpad problem was found in the fab process with hot Al alloy metallization, which had resulted in nonstick failure during the assembly bonding process. Analytical results indicated that discolored bondpads with nonstick failure might be due to TiN residue introduced during the bondpad opening etching process. The possible root cause of TiN residue on bondpads was then confirmed to be arisen from ARC (TiN) layer underetched during the bondpad opening etching process. The solution to eliminate TiN residue on bondpads was taken to increase the etch time at the bondpad opening fab process.

This paper reports on the thermal stress comparison between gold (Au) and copper (Cu) wires in wire bonding. The objective of this study is to examine the stress induced during different operating temperatures. ANSYS 11 has been deployed as the simulation tool for this study. This simulation was performed using a three dimensional (3D) non-linear finite element model. The gold and copper wires were attached to an aluminium bondpad on a silicon die. The results showed that when the highest stress concentrates at the area between the ball bond and the bondpad. Moreover, increasing temperature will increase the von mises stress. As for this study, the Cu wire display the greater thermal stress compared to Au wire due to its harder and stiffer material properties.

Tape automated bonding (TAB) is an interconnection technique for integrated circuits (ICs) with a small lead pitch and a thin assembly thickness. During inner lead bonding the flying (Au plated Cu) leads of the TAB foil are connected to the Au bumps on the bondpads of an IC. The Au bumps are deposited in the openings of a thick Novolac based resist layer by electroplating. The resist is coated on a sputtered TiW‐Au metallisation; TiW is the barrier layer between Au bump and Al bondpad. Bonding of the leads to the Au bumps requires substantial plastic deformation of the bump and lead. As a result of this deformation, the TiW barrier layer underneath the bump may crack easily. A theoretical model has been used to describe the occurrence of these cracks. This theoretical model is compared with experimental results of deformation and cracking behaviour by visual inspection of the TiW barrier and the etched cross‐sections. Separate (single point) and simultaneous (gang) bonding techniques, different gold plating baths and TAB tapes are used to study the cracking behaviour.

Wettability is one of the most important aspects in microfluid technology. The effect of surface roughness on the wettability by a liquid has been studied experimentally using Design of Experiment(DOE). Sixteen samples were etched using Reactive Ion Etching (RIE) technique with different combination of parameters. RIE parameters concerned in this experiment are ratio of Oxygen, Argon, ICP power and BIAS power. Reactive Ion Etching influences surface morphology which is correlated with the contact angle produced. This preliminary study is to gain information on the how does RIE affects the aluminum bondpad in terms of surface roughness and contact angle.

Bondpad cratering, Cu ball bond interface corrosion, IMD (intermetal dielectric) cracking, and uncontrolled post-wirebond staging are the key technical barriers in Cu wire development. This paper discusses the UHAST (unbiased HAST) reliability performance of Cu wire used in fine-pitch BGA package. In-depth failure analysis has been carried out to identify the failure mechanism under various assembly conditions. Obviously green mold compound, low-halogen substrate, optimized Cu bonding parameters, assembly staging time after wirebonding, and anneal baking after wirebonding are key success factors for Cu wire development in nanoelectronic packaging. Failure mechanisms of Cu ball bonds after UHAST test and CuAl IMC failure characteristics have been proposed and discussed in this paper.

Abstract Discolored bondpads & non-stick failure in 0.6 μm wafer fab process with the hot Al alloy metallization was investigated. SEM, EDX & AES techniques were used to identify the root causes. Failure analysis results showed that discolored bondpads & non-stick failure were caused by TiN residue introduced during L95 bondpad opening wafer fab process. TiN residue on bondpad might have led to non-stick bondpad issue. The results also showed that it was difficult to determine the trace amount of TiN residue on bondpad using EDX technique due to its limitations. In this work, Auger surface analysis technique was used to determine TiN residue on bondpads with Al/TiW/Ti metallization. Auger results showed that Ti & N peaks were detected on discolored bondpads. It has resulted in non-stick bondpad failure. The solution to eliminate TiN residue on bondpads was to increase etch time at L95 bondpad opening wafer fab process. After using the new recipe with longer etch time, Auger results on the bondpads showed that no Ti & N peaks were detected and the bond-pull testing also passed.

Abstract Galvanic corrosion (two metal corrosion) on microchip Al bondpads may result in discolored or non-stick bondpad problem. In this paper, a galvanic corrosion case at bondpad edge will be presented. Besides galvanic corrosion (Al-Cu cell), a concept of galvanic corrosion (Al-Ti cell) is proposed, which is used to explain galvanic corrosion at bondpad edge with layers of TiN/Ti/Al metallization structure. A theoretical model of galvanic corrosion (Al-Ti cell) is proposed to explain chemically & physically failure mechanism of galvanic corrosion at bondpad edge. According to the theoretical model proposed in this paper, galvanic corrosion on microchip Al bondpads could be identified into two corrosion models: galvanic corrosion (Al-Cu cell) occurred mostly at the bondpad center and galvanic corrosion (Al-Ti cell) occurred specially at bondpad edge with TiN/Ti/Al metallization structure. In this paper, a theoretical model of galvanic corrosion (Ai-Ti cell) will be detail discussed so as to fully understand failure mechanism of galvanic corrosion the bondpad edge. Moreover possible solutions to eliminate galvanic corrosion (Al-Ti cell) are also discussed.

Abstract In wafer fabrication, Fluorine (F) contamination may cause fluorine-induced corrosion and defects on microchip Aluminum (Al) bondpads, resulting in bondpad discoloration or non-stick on pads (NSOP). Auger Electron Spectroscopy (AES) is employed for measurements of the fluorine level on the Al bondpads. From a Process control limit and a specification limit perspective, it is necessary to establish a control limit to enable process monitor reasons. Control limits are typically lower than the specification limits which are related to bondpad quality. The bondpad quality affects the die bondability. This paper proposes a simulation method to determine the specification limit of Fluorine and a Shelf Lifetime Accelerated Test (SLAT) for process monitoring. Wafers with different F levels were selected to perform SLAT with high temperature and high relative humidity tests for a fixed duration to simulate a one year wafer storage condition. The results of these simulation results agree with published values. If the F level on bondpad surfaces was less than 6.0 atomic percent (at%), then no F induced corrosion on the bond pads was observed by AES. Similarly, if the F level on bond pad surfaces was higher than 6.0 atomic per cent (at%) then AES measured F induced corrosion was observed.

Abstract A failure analysis flow is developed for surface contamination, corrosion and underetch on microchip Al bondpads and it is applied in wafer fabrication. SEM, EDX, Auger, FTIR, XPS and TOF-SIMS are used to identify the root causes. The results from carbon related contamination, galvanic corrosion, fluorine-induced corrosion, passivation underetch and Auger bondpad monitoring will be presented. The failure analysis flow will definitely help us to select suitable methods and tools for failure analysis of Al bondpad-related issues, identify rapidly possible root causes of the failures and find the eliminating solutions at both wafer fabrication and assembly houses.

Abstract In wafer fabrication (Fab), Fluorine (F) based gases are used for Al bondpad opening process. Thus, even on a regular Al bondpad, there exists a low level of F contamination. However, the F level has to be controlled at a lower level. If the F level is higher than the control/spec limits, it could cause F-induced corrosion and Al-F defects, resulting in pad discoloration and NSOP problems. In our previous studies [1-5], the theories, characteristics, chemical and physical failure mechanisms and the root causes of the F-induced corrosion and Al-F defects on Al bondpads have been studied. In this paper, we further study F-induced corrosion and propose to establish an Auger monitoring system so as to monitor the F contamination level on Al bondpads in wafer fabrication. Auger monitoring frequency, sample preparation, wafer life, Auger analysis points, control/spec limits and OOC/OOS quality control procedures are also discussed.

Abstract Non-stick on pad (NSOP) is a yield limiting factor that can occur due to various reasons such as particle contamination, galvanic corrosion, Fluorine-induced corrosion, process anomalies, etc. The problem of NSOP can be mitigated through a careful process characterization and optimization. In this paper, a bondpad qualification methodology (OSAT) will be discussed. It will be argued that by employing different physical analysis techniques in a failure analysis of wafer fabrication, it is possible to perform comprehensive characterization studies of the Aluminum bondpad so as to develop a robust far backend of line process. A good quality Al bondpad must meet the following four conditions-OSAT: (i) it should be no discoloration (using Optical inspection); (ii) should be defect free (using SEM inspection); (iii) should be with low contamination level (such as fluorine and carbon contamination should be within a control limit) (using Auger analysis) and (iv) should have a protective layer on bondpad surface so as to prevent bondpad corrosion (using TEM).

Abstract Fluorine contamination on Al bondpads will result in corrosion, affect quality of bondpads and pose problem such as non-stick on pad (NSOP) during wire bonding at assembly process. In this paper, a fluorine contamination case in wafer fabrication will be studied. Some wafers were reported to have bondpad discoloration and bonding problem at the assembly house. SEM, EDX, TEM, AES and IC techniques were employed to identify the root cause of the failure. Failure analysis results showed that fluorine contamination had caused bondpad corrosion and thicker native aluminium oxide, which had resulted in discolored bondpads and NSOP. It was concluded that fluorine contamination was not due to wafer fab process, but was due to the wafer packaging foam material. XPS/ESCA and TOF-SIMS advanced tools were used to study the chemical and physical failure mechanism of fluorine-induced defects. An unknown Al compound was found using XPS technique and identified it as [AlF6]3- using electrochemical theories and TOF-SIMS technique. This finding was very significance, as it helped developing a theoretical electrochemical model for fluorine-induced corrosion and helped understanding of the mechanism of fluorine-induced corrosion on aluminium bondpads. It was found that fluorine contamination had formed [AlF6]3-on the affected bondpads and it had caused further electrochemical reactions and formed some new products of (NH4)+ and OH-. Then [AlF6]3- and (NH4)+ ions combined and formed a corrosive complex compound, (NH4)3(AlF6), while the OH- reacted with Al and caused further corrosion.

Abstract Bond pad characterization is usually performed by mechanical cross-sectioning as well as pull and shear tests. However, since all these methods apply mechanical forces to the bond pad, artifacts may result. Focused Ion Beam (FIB) characterization is a mechanically stress-free characterization method, which allows more accurate conclusions regarding the intermetallic behaviour of the bonding area. Some new approaches presented here show how to improve the FIB characterization procedure and to combine it with classical characterization methods.
