Paper Abstract

This paper treats a for the semiconductor industry somewhat different application: The first-ever manufacture of Diffractive Optical Elements (DOE’s) as directly written multilevel diffractive micro-reliefs using the DUV SLM-based Sigma7300 Mask. The reliefs were manufactured in the DUV Chemically Amplified Resist (CAR) FEP-171. This particular application is of direct interest since DOE’s are already incorporated in the Sigma7300 system. The design and manufacture are demonstrated with (1.) A Fan-out element and (2.) A logotype generator. The first attempts, reported here, resulted in a Fan-out element with diffraction efficiency of 64% compared to the theoretical design of 88%.
