4 Different Types of Lithography
Lithography is a technique used to transfer a two-dimensional pattern onto a flat surface. Depending on the required outcome, many lithography methods can be used. This blog post will cover the four different types of lithography techniques and their applications. The Different Types of Lithography When patterns need depositing, lithography is a process that utilizes UV light to transfer a geometric pattern onto a thin film or a substrate. This is carried out by spinning a layer of photoresist onto a piece of material and then exposing the photoresist to ultraviolet light. Before the photoresist is exposed, a mask is placed on top of the substrate to stop certain areas from being illuminated by the light. The geometric pattern is finally relieved by removing the unprocessed regions with the help of an aqueous solvent. One of the main reasons for
