Latest Patents

Ik Soo Choi holds a patent for a "Method for forming a capacitor of semiconductor device." This patent describes an improved method for forming a capacitor that increases cell capacitance. The method involves a sequential two-step etching process. The first step selectively etches to create a contact hole that exposes an etch stop layer between gate electrodes. The second step employs isotopically dry etching to maximize the capacitor's surface area without requiring a cleaning process after the selective etching. The interlayer insulating layer is patterned to produce inner interlayer contact sidewalls with standing wave ripples, effectively removing the exposed etch stop layer. As a result, the capacitor formed through this simple two-step dry etching exhibits an increased surface area. Furthermore, it allows for the creation of a stacked capacitor with sufficiently high storage capacitance without increasing contact resistance.
