Title: Yong Qiang Tang: Innovator in Semiconductor Technology

Introduction

Yong Qiang Tang is a prominent inventor based in Chengdu, China. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to wire bonding methods.

Latest Patents

One of his latest patents is titled "Ball bond attachment for a semiconductor die." This method involves forming a ball at the first end of a conductive wire inserted in a capillary tool. The process includes lowering the capillary tool toward a pad on the semiconductor die positioned on a support surface. A motor is used to move the support surface relative to the capillary tool, allowing the ball to bond to the pad without the use of ultrasound. After bonding, the capillary tool is raised.

Another notable patent is "Wire ball bonding in semiconductor devices." This method presents a technique for interconnecting components of a semiconductor device using wire bonding. It involves creating a free air ball at the first end of an aluminum wire coated with palladium. The free air ball is bonded to a bond pad on a semiconductor chip, which has an aluminum surface layer. This results in a homogenous aluminum-to-aluminum bond. Additionally, the method includes bonding a second end of the coated-aluminum wire to a separate bond site with a palladium surface layer, forming a homogenous palladium-to-palladium bond.
