Title: Hsueh-Liang Chiu: Innovator in Semiconductor Fabrication

Introduction

Hsueh-Liang Chiu is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of semiconductor fabrication, holding 2 patents that enhance the efficiency and quality of manufacturing processes.

Latest Patents

Chiu's latest patents include a simplified process for the fabrication of deep clear laser marks and a method for post-etching of metal patterns. The first patent describes a process for forming deep clear laser marks on silicon wafers. This process addresses the issue of tall ridges of material that erupt from the wafer surface during deep laser penetration. These ridges, which can reach heights of 3 to 15 microns, must be removed to prevent fragmentation and contamination during subsequent wafer processing. The invention involves depositing a non-conformal layer of photoresist or other flowable material on the wafer, allowing for the selective etching of the ridges while protecting the wafer surface.

The second patent presents an improved process for post-etching treatment after subtractive etching of aluminum and aluminum-alloy layers in semiconductor integrated circuit devices. This improvement consists of in situ exposure to a reactive plasma sustained in a mixture of oxygen and carbon tetrafluoride gases immediately after the subtractive etching of the metal pattern. This method enhances the quality of the metal patterns and contributes to the overall performance of semiconductor devices.
