FORMING VARIABLE DEPTH STRUCTURES WITH LASER ABLATION

Abstract:

A method for forming a device structure structure is disclosed. The method of forming a device structure structure includes forming a variable-depth structure in a device material layer using a laser ablation. A plurality of device structures is formed in the variable-depth structure to define slanted device structures therein. The variable-depth structure and the slanted device structures are formed using an etch process.
