Title: Cheng-Han Yang: Innovator in Image Sensor Technology

Introduction

Cheng-Han Yang is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in image sensor manufacturing. With a total of 4 patents to his name, Yang's work has had a substantial impact on the industry.

Latest Patents

Yang's latest patents include a manufacturing method of an image sensor. This method involves several steps, starting with the provision of a substrate. A light sensing device is formed within the substrate, along with a storage node that is separated from the light sensing device. A buried gate structure is then created, which includes a buried gate and a first dielectric layer. The buried gate covers part of the storage node, while the first dielectric layer is positioned between the buried gate and the substrate. Additionally, a first light shielding layer is formed on the buried gate, which is electrically connected to the buried gate and located above the storage node.

Another notable patent is related to anti-reflective coating by ion implantation for lithography patterning. This method includes depositing a target layer over a substrate, which consists of an inorganic material. Ions are implanted into the target layer, resulting in an ion-implanted target layer. A photoresist layer is then formed directly over this ion-implanted layer and exposed to radiation during a photolithography process. The ion-implanted target layer effectively reduces the reflection of radiation back to the photoresist layer, enhancing the lithography process.
