Title: Improved critical dimension (cd) uniformity of photoresist island patterns using alternating phase shifting mask
Inventor: HAQ JESMIN
IPC: G03F1/30
Filed: 2019-09-17
Abstract: Critical dimension uniformity is improved and a photoresist film is patterned into an array of island shapes without a phase edge by using two alternating phase shifting masks (AltPSM) and one post expose bake (PEB). A photoresist layer is exposed by using a first AltPSM having a line/space (L/S) pattern and light is phase-shifted at 180° through alternating clear areas on each side of opaque lines. And then, there is a second exposure using a second AltPSM with an L/S pattern, wherein the opaque lines are aligned orthogonally to the length dimension of the opaque lines in a first exposure and have alternating clear areas of 0° and 180°. Then the PEB and a subsequent development process are used to form the array of island shapes. The double exposure method enables a smaller island shape than conventional photolithography and uses a relatively simple AltPSM design which is easier to implement in production than other optical enhancement techniques.
