Etch characteristics of KOH, TMAH and dual doped TMAH for bulk micromachining of silicon

Microelectronics Journal, 2006
Abstract High precision bulk micromachining of silicon is a key process step to shape spatial structures for fabricating different type of microsensors and microactuators. A series of etching experiments have been carried out using KOH, TMAH and dual doped TMAH at different etchant concentrations and temperatures wherein silicon, silicon dioxide and ...

Effect of cations on silicon anisotropic etching process in solutions containing TMAH and TMAH with tensioactive compounds

Sensors and Actuators A: Physical, 2020
Abstract Almost everything has been written on silicon anisotropic etching in alkaline solutions, however, the difference between etching in pure KOH and TMAH as well as in these solutions containing tensioactive compounds has not been completely elucidated yet.

Experiments on anisotropic etching of Si in TMAH

Solar Energy Materials and Solar Cells, 2001
Abstract Recently, TMAH has been widely studied due to its MOS compatibility, nontoxic, and good anisotropic etching characteristics. In this work, TMAH etching of Si was carried out at different temperatures (70°C, 80°C and 90°C) and concentrations (5, 15 and 25 wt%). From a patterned Si wafer, inverted pyramids with smooth surface and sharp pyramid

pH-controlled TMAH etchants for silicon micromachining

Sensors and Actuators A: Physical, 1996
The etching characteristics of pH-controlled tetramethyl ammonium hydroxide (TMAH) by dissolving Si or acid have been studied. TMAH with 10 and 22 wt.% at 80/spl deg/C were used as etchants, (NH/sub 4/)/sub 2/,CO/sub 3/ and (NH/sub 4/)HPO/sub 4/ were used as acid.
