Title: The Innovations of Chu-Chang Chen

Introduction

Chu-Chang Chen is a prominent inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on enhancing integrated circuit designs and improving manufacturing processes.

Latest Patents

One of his latest patents is titled "Semiconductor devices having post passivation interconnections and a buffer layer." This patent discloses an integrated circuit that features post passivation interconnections with a second connection pattern. A passivation layer, preferably made of a non-oxide material, is formed over the integrated circuit, which already has a first plurality of contact pads in a first connection pattern. A buffer layer, ideally a silicon oxide layer, is then formed over the passivation layer, with a thickness substantially smaller than that of the passivation layer. A post passivation metal layer is deposited over the buffer layer, and a second plurality of contact pads is created in the post passivation metal layer as part of the second connection pattern.

Another significant patent by Chen is the "Method for reducing defects in post passivation interconnect process." This patent outlines a method for forming post passivation interconnects for an integrated circuit. Similar to his previous patent, a passivation layer of a non-oxide material is formed over the integrated circuit, followed by the formation of a buffer layer. A post passivation metal layer is then deposited over the buffer layer, and a connection pattern is established in the post passivation metal layer.
