Title: Hsien-Wen Wan: Innovator in Semiconductor Technology
Introduction
Hsien-Wen Wan is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 8 patents. His innovative work has advanced the manufacturing methods and design of semiconductor devices.
Latest Patents
One of Hsien-Wen Wan's latest patents is focused on a semiconductor device and its manufacturing method. This method involves forming a semiconductive channel layer on a substrate, followed by the creation of a dummy gate on the channel layer. Gate spacers are then formed on either side of the dummy gate. After the removal of the dummy gate, a gate trench is created, exposing the semiconductive channel layer. A semiconductive protection layer is deposited in the trench, and the top portion of this layer is oxidized to form an oxidation layer. The oxidation layer undergoes annealing, leading to the formation of a gate structure over the protection layer and within the trench. The semiconductor device itself includes a substrate, a semiconductor fin, a silicon layer, a gate structure, gate spacers, and source/drain structures, showcasing the complexity and innovation in his designs.
