KOH Etching - BYU Cleanroom
If silicon nitride is being used as a mask for silicon etching, potential etching of the silicon nitride need not be taken into consideration. KOH etching of silicon dioxide is observable. The etch rates are considerably slower (1-2 orders of magnitude) than that of silicon but should be considered when deep etching is being done.
Rugate Optics: Chemically resistant porous silicon carbide spectral optics could have biosensing uses Extremely fine porous structures can be generated in semiconductors, opening up new possibilities for novel sensors, optics, and electronics -- experiments in this area have already been done in silicon.

Alel Speeder 100 SiO 2 The Alel "Speeder 100SiO 2" is an ICP Etching system which is configured for etch silicon using either the patented BOSCH Deep Silicon Etch Process or a Cryogenic etch process that are typically used in MEMS (Micro-ElectroMechanical Systems), microfluidics, and silicon masters for soft lithography stamps.
Micro ring resonator has highest silicon carbide quality …
2019/7/8· To deposit and etch the silicon carbide waveguide on silicon oxide, Ma first used electron beam lithography to pattern the waveguides and reactive ion dry etching to remove excess silicon carbide. But his first attempts using a typical polymer-based mask didn’t work because the process removed more of the mask than the silicon carbide.

Silicon Carbide Structure Material for Optical Communiion
Silicon carbide as structure layer is able to withstand higher temperature and can be modulated either electrostatically or using other actuation techniques. 4.2 Silicon Carbide (SiC) as Structure Layer The etched polycystic 3C-SiC films were grown on silicon
Beads By Laura: Tule-etching lampwork beads
2016/3/11· As I''ve said, you can experiment with different grade silicon carbide grits, different types and sizes of tuling matter, and the types and styles of lampwork beads you want to etch. There are several glasses that don''t like chemical etching and they stay shiny or go patchy, so tule-etching is a fab solution to that problem.
Glass grinding with silicon carbide by hand -
2013/5/14· In this video, Bob demonstrates how to use loose grit silicon carbide to grind your glass by hand without using any machinery at all. A fairly straightforward process, it often comes in handy for
Etching - Australian National Fabriion Facility – …
Standard processes include resist or organic strip using oxygen and oxide/nitride/silicon carbide etch processes using SF 6 chemistry. As SF 6 has one of the highest global warming potentials, the system exhaust is scrubbed by a BOC Thermal Processing Unit (TPU), which breaks down the exhaust gases to eliminate any environmental impact—targeting zero toxic and global warming gas emissions

A practical guide for the fabriion of microfluidic …
2012/3/5· The remaining advantages of silicon and glass Certain micro- and nano-fluidic appliions demand high temperature resilience (e.g., for chemical synthesis 4), the precise definition of nano-scale channels or pores, 24, 25 high aspect ratio structures (usually up to 20:1), the integration of electrodes, or even integration with electronic circuits.
Smart-Cut Layer Transfer of Single-Crystal SiC Using Spin-on-Glass
The authors demonstrate “smart-cut”-type layer transfer of single-crystal silicon carbide (SiC) by using spin-on-glass (SoG) as an adhesion layer. Usin g SoG as an adhesion layer is desirable because it can planarize the surface, facilitate an initial low
