With advancement of MEMS technology, the reliability of a microstructure has become a vital issue before a microdevice is widely accepted. Consequently, it is indispensable to understand the mechanical properties of a microstructure to meet the requirements of longer lifetime and reliable performance. This study investigates the fatigue characteristics of a microcantiliever beam (60-120μm long, 20μm wide, 2μm thick), one of the most common microstructures widely employed in sensors and actuators. Furthermore, a pad (500×500×2 and 560×560×2μm3 ), fabricated at the free end of the beam, is used for larger external electrostatic load generated between the specimen and the electrode with an air gap 525μm. In fatigue test, the specimen actuated by the applied voltage 150 and 200 V in the form of the digital wave at 100 Hz. The deflection of the beam is measured by the laser Doppler vibrometer. According to the experimental and ANSYS results, the displacement of the free end of the beam increases with the beam length, ranging from 61.3 to 597.8 nm; from S-N diagram, the maximum stress is inversely proportional to the corresponding fatigue life. The maximum stress occurs at the fixed end of the specimen between 14.3–32.0 MPa; the fatigue life lies between 6.1×10^6–1.4×10^8 cycles.

This research focuses on the fabrication of a cantilever beam microstructure on a stainless steel substrate (SUS-301). Electroforming of a copper sacrificial layer and a nickel structural layer are used in the microfabriction process. A negative photoresist JSR-120N is used in the lithography process. The process parameters of soft bake, exposure and development are investigated. Pulse current is used in the electroforming process. A nickel cantilever beam is successfully fabricated by using a copper sacrificial layer and a nickel structural layer.

In light of the rapid advancement in IC/MEMS/NEMS technology, the reliability is an essential factor for a successful microdevice product. However, the reliable application of these devices often depends on the fatigue of their microstructure. Microcantilever beam and polycrystalline silicon (polysilicon) are the most often used structure and material in microdevices, respectively. Therefore, their mechanical fatigue properties need to be characterized to predict the lifetime of the microdevices. This study presents the fatigue life of polysilicon microcantilever beam in bending by various testing methods, including microactuator, MTS Tytron250 microforce testing system and piezoelectric actuator. During microactuator testing, the fatigue life persists up to millions of cycles without failure, because the amplitude of displacement is small. Based on the results of the MTS Tytron250 microforce testing system and the piezoelectric actuator, it can be concluded that large stress reduces the number of cycles, namely the fatigue life is inversely proportional to the stress. In this study, an empirical correlation is established for predicting bending fatigue of polysilicon microcantilever beam. This correlation demonstrated the influence of applied frequency on fatigue life. The high stress reduced the fatigue life, and low frequencies enhanced this effect. Moreover, the collective plot of polysilicon by various testing mechanisms, such as tension, bending and torsion, will provide the microdevice designer and researcher with a good reference for various applications.

Prostate cancer is becoming one of the top three major cancer killers for elderly men in the west, and it is also one of the ten major cancers reported of Taiwan in 2006. Prostate specific antigen (PSA) is found to be the most valuable tumor sign of prostate cancer. It has become the highest value of biomarkers in cancers. In this study, the piezoresistive microcantilever is required for operation in a phosphate buffered saline solution or human plasma which is to maintain a specific pH environment of a strong electrolyte. As a result, the device is required to be electrically insulated in solution environment. The selected silicon nitride is used to conform to the requirements for the insulting material. The cantilevers are designed in 150 or 200 μm long, 50 μm wide and about 1.4 μm thick. The integrated piezoresistive resistors are 100 μm long, 50 μm wide and 200 nm thick, and the expected resistance is approximately 4 kΩ. Meanwhile, the gold layer (30 nm thick) coated on the cantilever surface is necessary for chemical reaction of biolinker, and thus the sensing surface of specific protein adsorption and its associated recognition. In addition to the microcantilever device, several important issues need to be considered in height, length, width, and the total volume of the channel, as well as the flow field in the microchannel. In the micro-fluid system, the laminar flow is also required to reduce the noise from vibrations of the cantilever. The biosensor is wire bonded directly on the printed circuit board (PCB) with a height of 470μm, connected to the signal processing device on the PCB. Preliminary result of PSA detection was obtained by this piezoresistive microcantilever. The device is confirmed to be tested in solution environment and thus its preliminary feasibility. More testing is required for further verification in PSA detection.

C-reaction protein( CRP ) is becoming one of important biomarkers in cardiovascular disease, myocardial infarction( MI ), and atherosclerosis. Higher concentration of CRP in serum elevates the risk of those diseases. Despite of existing techniques of surface plasmon resonance( SPR ), enzyme-linked immunosorbent assay( ELISA ) and others developed, the present piezoresistive microcantilever biosensors are sensitive, potentially inexpensive, label-free and of ease-of-use in miniaturization. To be detected, the microcantilevers are placed inside a microfluidic system that has a volume of several ten microliters. As probed biomolecules are transported onto a sensing surface of microcantilevers, specific recognition occurs, resulting in biomolecular conformation change and associated nanomechanic deflection of induced surface stresses. The deflection is mostly detected by an optical lever of detection system. Despite sensitive detection, the entire optical measurement is bulky and hardly aligned in readout system. For biomolecular recognition, the piezoresistive cantilever is required for operation in a phosphate buffered saline solution or human plasma which is to maintain a specific pH environment of a strong electrolyte. As a result of device electrical insulation to its solution, the piezoresistive cantilever is required to be surrounded by the insulating material to prevent electric leakage and unwanted chemical reaction on the sensing surface. The selected silicon nitride is used to conform to the requirements for the insulting material. The cantilevers are designed in 150 or 200 μm long, 50 μm wide and about 1.4 μm thick. The integrated piezoresistive resistors are 100 μm long, 50 μm wide and 200 nm thick, and the expected resistance is approximately 4 kΩ. Meanwhile, the gold layer (30 nm thick) coated on the cantilever surface is necessary for chemical reaction of biolinker, and thus the sensing surface of specific protein adsorption and its associated recognition. Preliminary result of CRP detection was obtained by this piezoresistive microcantilever. The device is confirmed to be tested in solution environment and thus its preliminary feasibility. More testing is required for further verification in CRP detection.
