Title: Mario Merlin and His Semiconductor Packaging and Welding Patents.

Introduction

Mario Merlin is an inventor associated with San Carlo Canavese, Italy. His work includes inventions in semiconductor packaging and metal joining, and he is credited with 4 patents. He worked at International Rectifier Corporation.

Latest Patents

One of Merlin’s latest patents, “Compression Assembled Electronic Package Having a Plastic Molded Insulation Ring,” describes a package for a power semiconductor die. Two pole pieces make electrical contact with the die’s major electrodes, while a molded plastic insulation ring surrounds the die and secures the pole pieces. The design may use an annular flange embedded in the ring, with a tab-and-cavity arrangement that helps hold the components together.

Another patent, “Process to Weld Steel to Copper,” presents a method for joining a steel terminal to a copper electrode. It applies a thin silver-copper flash to the copper surface before high-frequency welding. The described process produced uniform, high-quality welds, including with a silver alloy containing 18 percent copper.
