Latest Patents

One of his latest patents is a method for forming a capacitor of a semiconductor device. This innovative approach enhances cell capacitance through a sequential two-step etching process. The first step involves selectively etching to create a contact hole that exposes an etch stop layer between gate electrodes. The second step utilizes isotopically dry etching to maximize the capacitor's surface area without requiring a cleaning process after the selective etching. This method results in a capacitor with an increased surface area and allows for the formation of a stacked capacitor with high storage capacitance while maintaining low contact resistance.

Another significant patent by Sang Wook Kim is a method for fabricating a semiconductor device with a tapered contact. This design includes a field oxide layer on a semiconductor substrate and a transistor with an active region. The tapered contact hole exposes the active region adjacent to the field oxide layer, ensuring that the upper portion of the hole is wider than the lower portion. This design prevents the field oxide from being etched during the contact hole etching process, thereby enhancing the integrity of the semiconductor device.
