Title: **Innovations by Chung Hsiung Ho: A Trailblazer in Semiconductor Technology**

Introduction

Chung Hsiung Ho, an innovative inventor based in Kaohsiung, Taiwan, has made significant contributions to the field of semiconductor technology. With a total of seven patents to his name, Ho has demonstrated ingenuity and expertise in developing advanced semiconductor devices that enhance performance and reliability.

Latest Patents

Among his latest inventions is a groundbreaking **semiconductor device with conductive film shielding**. This innovative packaged semiconductor device features a conductive film that covers the first major surface and surrounding side surfaces of an integrated circuit die. This design provides five-sided shielding, ensuring effective protection for the integrated circuit die. Additionally, a metal heat sink can be attached to an exposed major surface of the conductive film, facilitating the dissipation of heat generated by the die.

Another remarkable patent is the **solderless inter-component joints** technology. In a die-substrate assembly, Ho has developed a method where a copper inter-component joint is formed by directly bonding corresponding copper interconnect structures without the use of solder. This method utilizes distal layers of (111) crystalline copper, allowing for bonding at relatively low temperatures below 300 °C, compared to the high melting point of bulk copper at approximately 1085 °C. By avoiding solder, this technology eliminates adverse intermetallic compound/electromigration effects that are common in traditional solder-based joints. Furthermore, the interconnect structures may have curved distal surfaces to enhance the reliability of the contact, achieved through directed microwave radiation and microwave-sensitive flux.
