A wafer comprising a GaAs substrate and an AlGaAs layer deposited thereon is rotated in a spin etching process. To the GaAs substrate of the rotating wafer, there is supplied an ammoniacal etching solution for selectively etching the GaAs substrate to form a groove therein. The ammoniacal ...
RENA Technologiesoffers batch, single wafer and spray semiconductor etching equipment, tailored to meet the diverse demands. Our surface treatment tools are designed to process a wide range of semiconductor materials, including Silicon (Si), Silicon Carbide (SiC), Gallium Nitride (GaN), Gallium Arsen...
Accurate & Safe Wet Etching Process Solutions Wet etch is typically used to remove a top layer from a semiconductor wafer, without harming the structure underneath that film, or etch cavities into a wafer - parts of which are protected by a mask. Wafers are either immersed in a bath, or ...
Etching processes often go too far in an attempt to ensure that all the intended metal is removed; however, that can cause undercutting of the bump, which is not desirable. The ACM wet etcher is designed to precisely control the process and avoid undercutting while ensuring a uniform etch of...
