Latest Patents

Dong Myung Lee holds 1 patent for his invention titled "Method for forming a capacitor of semiconductor device." This patent discloses an improved method for forming a capacitor that increases cell capacitance. The method involves a sequential two-step etching process, which includes selectively etching to create a contact hole that exposes an etch stop layer between gate electrodes. Additionally, isotopically dry etching is employed 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, allowing for the creation of a stacked capacitor with high storage capacitance without increasing contact resistance.
