Latest Patents

Wang's latest patents include a "Patterning method using stacked structure." This patent describes a stacked structure for patterning a material layer to form an opening pattern with a predetermined opening width. The structure consists of an underlayer, a silicon-rich organic layer, and a photoresist layer. The underlayer is positioned on the material layer, while the silicon-rich organic layer is sandwiched between the underlayer and the photoresist layer. The thickness of the photoresist layer is smaller than that of the underlayer and larger than twice the thickness of the silicon-rich organic layer. Additionally, the thickness of the underlayer is less than three times the predetermined opening width.

Another significant patent is the "Method of fabricating spacers and cleaning method of post-etching and semiconductor device." This patent outlines a method for fabricating spacers, which involves providing a substrate with a device structure formed thereon. The device structure includes a gate structure and a pair of source/drain regions. A spacer material layer is formed over the substrate, followed by an etching process to create spacers on the sidewalls of the gate structure. A plasma treatment step is then performed to form a spacer protection layer on the substrate, spacers, and gate structure.
