WebThe role of the lithography process in overall integrated circuit fabrication can be appreciated by considering the sequence of deposition, lithography, and etch steps used to establish electrical contacts to the transistors that make up integrated circuits (Fig. 1.1). Electrical interconnections are made after the WebIn soft lithography, the fabrication of a mold, often made in SU-8, is required for replicating PDMS microfluidic structures. For the fabrication of this SU-8 master, a standard photolithography process is commonly used. Therefore, a first key concern is to apply a coating of SU-8 photoresist layer on a silicon wafer, as shown in Figure 1. WebSep 16, 2013 · 3.
