Abstract:
1. A method of depositing material on a substrate in a combinatorial manner, the method comprising: providing a substrate comprising a plurality of site-isolated regions, positioning the each of the plurality of site-isolated regions directly under the aperture using a substrate positioning system, depositing a first material on the first site-isolated region using plasma enhanced chemical vapor deposition (PECVD) or plasma enhanced atomic layer deposition (PEALD) under a first set of process parameters; varying the first set of process parameters in a combinatorial manner to yield a second set of process parameters; and depositing a second material on the second site-isolated region using PECVD or PEALD under the second set of process parameters; wherein at least one of the depositing a first material or the depositing a second material is further controlled by placing a barrier at an edge of the aperture,
