Title: Chih-Hung Chang: Innovator in Semiconductor Technology
Introduction
Chih-Hung Chang is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of metal oxide semiconductors.
Latest Patents
One of his latest patents is for a metal oxide semiconductor with multiple drain vias. This innovative design includes a semiconductor substrate divided into a gate region, a source region, and a drain region. A connection layer made of low-resistance metal material is formed on the same surface of the substrate in both the source and drain regions. This allows for the arrangement of conductive elements, such as solder balls, directly on the connection layer, facilitating soldering to circuit boards. The design features multiple vias in the drain region, filled with the connection layer, which extends into the substrate, resulting in a low on-resistance R for the MOS.
Another notable patent is for a semiconductor package element. This element comprises a die with three surfaces, a passive layer, a conductive structure, and an encapsulation layer. The passive layer is formed with a hole on the first surface of the die, allowing the conductive structure to be electrically coupled through this hole. The encapsulation layer covers the first and third surfaces, embedding the passive layer and part of the conductive structure, while allowing another part to protrude from an etched surface formed by plasma etching.
