Ion mill photoresist etch rate
Web11 apr. 2024 · One of the most significant benefits of RIE over other chemical etching methods is its ability to achieve high etch rates and anisotropy. The ion bombardment in RIE allows better control of the etching direction compared to isotropic plasma etching. The direction control results in sharp and well-defined features with minimal undercutting. WebThe etch rates were obtained from stylus profilometry of the features after removal of the resist. Ion milling was performed in a Technics Micro Ion Mill [Model MIM (TLA 20)] …
