Latest Patents

One of Chih-Jung Ni's latest patents is a double-patterning method designed to improve sidewall uniformity. This method involves several steps, including the sequential formation of a doped polysilicon layer, a core layer, and an undoped polysilicon layer on a target layer. The undoped polysilicon layer is patterned to create a polysilicon pattern, followed by a first etching process that uses this pattern as a mask to remove part of the core layer, forming a core pattern. A second etching process removes the polysilicon pattern, and an atomic layer deposition (ALD) process is performed to create a spacer material on the core pattern and the doped polysilicon layer. This innovative approach enhances the uniformity of semiconductor devices.

Another significant patent by Ni involves a method for fabricating a semiconductor device. This method includes forming a plurality of first vias in a first dielectric layer within a memory cell region and a peripheral region. A surface treatment is applied to these vias to create sacrificial layers, which are then removed to form recesses. Protective layers are formed in these recesses, and a memory device is constructed on the first dielectric layer. A second dielectric layer is added, and second vias are formed to electrically connect the memory device and the first vias, ensuring efficient operation.
