Title: Innovations of Yunfei Li
Introduction
Yunfei Li is a prominent inventor based in Singapore, SG. He has made significant contributions to the field of semiconductor technology. With a total of 4 patents, his work focuses on enhancing transistor structures.
Latest Patents
One of his latest patents is titled "Transistor structure with air gap and method of fabricating the same." This invention includes a substrate with a transistor disposed on it. An etching stop layer covers and contacts both the transistor and the substrate. A first dielectric layer is placed over the etching stop layer, followed by a second dielectric layer. A trench is created on the gate structure within both dielectric layers. Notably, the width of the trench in the second dielectric layer is smaller than that in the first. A filling layer is then added within the trench, covering the top surface of the second dielectric layer, resulting in the formation of an air gap within the filling layer.
