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.

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.

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 -

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

2006/8/30· Etch rates of polycrystalline β-silicon carbide (SiC) substrate in a wide range from less than one to more than 10 μm/min are obtained using chlorine trifluoride gas in aient nitrogen at 673–973 K and atmospheric pressure in a horizontal reactor. Over the chlorine

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
