Fabrication of recessed-gate AlGaN/GaN MOSFETs using TMAH wet etching with Cu ion implantation

Results in Physics
In this study, recessed-gate AlGaN/GaN MOSFETs were fabricated using a novel recess etching method––TMAH wet etching with Cu ion implantation. This innovative approach injects Cu ions selectively into the target AlGaN layer, creating defects that are ...

WET ETCHING OF OPTICAL THIN FILMS

, 2010
Evaluation of the wet etching properties of several different thin film oxidesgrown by physical vapour deposition was performed in this work. MgO, Al2O3,SiO2, TiO2, HfO2 ZrO2 and Y2O3 were coated on two types of substrates; Si andborosilicate glass and etching tests were performed in different etchingsolutions. MgF2 thin films have also been evaluated.

Investigation of a Macromolecular Additive on the Decrease of the Aluminum Horizontal Etching Rate in the Wet Etching Process

Metals, 2022
The effect of a macromolecular additive on the etching rate of aluminum (Al) horizontal etching in the wet process was investigated in this work. The horizontal etching in the Al wet etching process became more evident as the film Al becomes thicker. The
