Latest Patents

Ja-Young Choi's latest patents include groundbreaking methods of manufacturing an image device. In this method, a first structure is created on a substrate with a photodiode, which consists of a transparent lower portion and an opaque upper portion. An etch stop layer pattern is then formed over the photodiode on this first structure. Following this, a second structure with at least one opaque capping layer is added to cover the etch stop layer pattern. An opening is created to partially expose the lower portion of the first structure by etching through the second structure, the etch stop layer pattern, and the opaque upper portion of the first structure.

Another notable patent is a method for forming a fuse integrated with a dual damascene process. This method involves creating an interconnection pattern and a fuse pattern on a substrate using a damascene process. A passivation layer is applied over the substrate's surface, and then it is patterned to form a pad opening that reveals part of the interconnection pattern. A metal pad is formed in this opening, extending over the passivation layer, while the passivation layer on the fuse pattern is partially etched to create a fuse opening.
