Refractory Materials - an overview | ScienceDirect Topics

Due to the nature of the evaporative process, the flux of materials arriving onto the resist pattern has a specific line-of-sight for all the different points on the substrate, as shown in Fig. 3 a. As a result, the evaporated film may have a poor conformity to the resist profile due to shadowing, and the coverage at the bottom of the resist pattern will be limited, as shown in Fig. 3 b.
