Title: Innovations by Chia-Chi Hsiao
Introduction
Chia-Chi Hsiao is a notable inventor based in Changhua County, Taiwan. He has made significant contributions to the field of semiconductor image sensors, holding a total of 5 patents. His work focuses on enhancing image quality and reducing dark current in image sensors, which are crucial for various imaging applications.
Latest Patents
One of Hsiao's latest patents is titled "Dark current reduction for back side illuminated image sensor." This patent discloses a method of fabricating a semiconductor image sensor device. In this method, a plurality of radiation-sensing regions is formed in a substrate, specifically in a non-scribe-line region of the image sensor device. An opening is created in the scribe-line region of the device by etching the substrate, leaving a portion of the substrate intact. This opening is then filled with an organic material, which contributes to the overall performance of the sensor.
Another significant patent is "Process for enhancing image quality of backside illuminated image sensor." This method involves providing a substrate with a first surface and a second surface, where the first surface is opposite the second. A light sensing region is formed at the first surface, and a doped layer is created at the second surface using a laser annealing process. The process concludes with a chemical mechanical polishing step on the annealed, doped layer, which enhances the image quality of the sensor.
