Introduction

Chen Yu Chen is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of laser technology, particularly in the development of vertical cavity surface emitting lasers (VCSELs). With a total of five patents to his name, Chen has established himself as a key figure in the semiconductor industry.

Latest Patents

Chen's latest patents focus on techniques for vertical cavity surface emitting laser oxidation. One of his notable inventions relates to a method for forming a VCSEL structure. This method includes forming an optically active layer over a lower reflective layer and creating an upper reflector over the optically active layer. A first spacer is formed along the sidewalls of the upper reflector. An oxidation process is then performed with the first spacer in place to oxidize a peripheral region of the optically active layer. Following this, a first etch process is executed on the lower reflective layer and the oxidized peripheral region, resulting in the formation of a lower reflector and an optically active region. Another patent describes a VCSEL device that includes a VCSEL structure overlying a substrate, featuring a first reflector, a second reflector, and an optically active region situated between the two reflectors. A first spacer laterally encloses the second reflector, comprising a first plurality of protrusions along the sidewall of the second reflector.
