Latest Patents
One of Jet-Rung Chang's latest patents is a formation method of a semiconductor device with a gate all around structure. This method involves creating an n-type doped region in a semiconductor substrate and forming a semiconductor stack over it. The stack consists of multiple sacrificial and semiconductor layers arranged alternately. The process includes introducing n-type dopants from the doped region into the stack, patterning it to create a fin structure, and forming a dummy gate stack around part of the fin. The dummy gate stack and sacrificial layers are then removed to release semiconductor nanostructures, followed by the formation of a metal gate stack around these structures.
Another notable patent is a metrology system and measurement method that focuses on thickness measurement. This method entails forming an implantation region in a semiconductor substrate and generating modulated free carriers within it. A probe beam is directed onto the semiconductor layer and the implantation region, with the reflected beam being detected to determine the thickness of the semiconductor layer.
