Title: Nung-Che Cheng: Innovator in Semiconductor Technology
Introduction
Nung-Che Cheng is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents focuses on "Germanium hump reduction." This patent provides methods for forming semiconductor devices. The method includes receiving a workpiece that consists of a stack of semiconductor layers. It involves depositing a first pad oxide layer on a germanium-containing top layer of the stack, followed by a second pad oxide layer on the first pad oxide layer. Additionally, a pad nitride layer is deposited on the second pad oxide layer, and the stack is patterned using these layers as a hard mask. The process specifies that the depositing of the first pad oxide layer utilizes a first oxygen plasma power, while the second pad oxide layer is deposited with a greater second oxygen plasma power.
