Latest Patents

One of Myoung Sik Chang's latest patents is titled "Semiconductor device and method for fabricating the same." This patented method involves a series of intricate steps designed to fabricate a semiconductor device. The process includes forming a mold structure consisting of a mold layer and a supporter layer over a semiconductor substrate. An opening is created that penetrates the mold structure, followed by the application of a protective layer on the bottom surface and sidewalls of the opening. Following this, a lower electrode is formed over the protective layer. The supporter layer is selectively etched to create a supporter that supports the lower electrode.

Furthermore, the mold layer is removed to reveal both a non-exposed portion and an exposed portion on the outer wall of the protective layer. Lastly, the exposed portion of the protective layer is trimmed selectively to form a pattern situated between the supporter and the lower electrode. This meticulous approach not only enhances the functionality of semiconductor devices but also contributes to the efficiency of their fabrication.
