Lateral Accelerometer Based on Sub-Micron Standing Piezoresistive
Cantilever with Thick Photoresist Proof Mass

phan1
 

We developed a piezoresistive accelerometer using submicron cantilever. Since the thickness of cantilever is 300nm, it offers high resolution with the piezoresistance change is 1.92~10-3 [G-1] even with a small proof mass made by spincoating 30m-thick KMPR-1035 photoresist on the surface. Furthermore the sensor functions as a lateral accelerometer by applying residual force to bend cantilever standing out of SOI wafer.
