Figure 1 illustrates a typical photolithography process used to define shallow trench isolation features. Such a process consists of the following steps: Substrate cleaning and preparation. Form layers of thermal oxide and deposit a layer of silicon nitride on the clean substrate.
Webbgeneral, modern photolithography involves a procedure with five steps; wafer preparation, application of photoresist, pre-exposure bake, exposure, post-exposure bake, and development. In photolithography, a wafer is a thin slice of semi conductive material, such as crystalline silicon, that forms the base for the photolithographic process. WebbPhotolithography refers to a binary image transfer process that can be used to enhance many microfabrication applications. The fundamentals of preforming photolithography consist of the following procedures: Surface Cleaning Spin Coating Soft Baking Exposure & Masking Post-Exposure Bake (PEB) Development Hard Bake Surface Cleaning
