Latest Patents

One of Yong-Jin Liou's latest patents involves techniques for forming a deep trench isolation structure between photodiodes. This innovation utilizes double patterning techniques to reduce corner rounding, etch loading, and other defects that may arise during the formation of a deep trench isolation (DTI) structure in a pixel array. The method includes forming a first set of trenches in one direction and a second set in another direction, ensuring minimal to no etch loading and corner rounding at the intersections of the trenches. Another notable patent focuses on implantation mask formation techniques. This patent describes a method to increase the initial aspect ratio of a pattern in an implantation mask using non-lithography techniques. By forming a resist hardening layer on the implantation mask, the height of the pattern is increased while the width is reduced, resulting in an ultra-high aspect ratio that minimizes the likelihood of pattern collapse during formation.
