The surface/bulk micromachining (SBM) process: a new method for fabricating released MEMS in single crystal silicon
TL;DR: The surface/bulk micromachining (SBM) process as discussed by the authors was proposed to fabricate released microelectromechanical systems using bulk silicon, where the exposed bare silicon is further reactive ion etched, which defines sacrificial gap dimensions and the final release is accomplished by undercutting the exposed bulk silicon sidewalls in aqueous alkaline etchants.
Journal ArticleDOI
Surface/bulk micromachined single-crystalline-silicon micro-gyroscope
TL;DR: In this paper, a triple-layer isolation method was proposed for high-aspect-ratio structures with sacrificial gaps, based on a single-crystalline-silicon micro-gyroscope fabricated using surface/bulk micromachining (SBM) process.
Proceedings ArticleDOI
