Abstract
The present invention relates to methods for controlling the etching rate of CoSi,layers by adjusting the pH of an HF-based solution to obtain the desired etch rate. The pH of the HF-based solution may be adjusted by adding pH modifying chemicals to the solution. A further aspect of the invention is an improved method for manufacturing Schotky barrier infared detectors employing the controlled etching step. A method for reducing drain induced barrier lowering in an active transistor having a small gate length is also provided.
