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

Electrostatic actuation of surface/bulk micromachined single-crystal silicon microresonators

TL;DR: This paper presents electrostatic actuation of a resonator fabricated by the SBM (surface/bulk micromachining) process, and a junction isolation method using reverse-biased diodes is developed.
Journal ArticleDOI

Carbon Nanotube Field Emitters Synthesized on Metal Alloy Substrate by PECVD for Customized Compact Field Emission Devices to Be Used in X-Ray Source Applications.

TL;DR: A simple, efficient, and economical process is reported for the direct synthesis of carbon nanotube (CNT) field emitters on metal alloy and an X-ray generated image of an integrated circuit was taken using the compact field emission device developed herein.
Journal ArticleDOI

A novel 3D process for single-crystal silicon micro-probe structures

TL;DR: In this article, a 3D fabrication method for a single-crystal silicon micro-probe structure is developed, which is based on surface/bulk micromachining technology.
