Title: Avishay Katz: Innovator in Bonding Technologies

Introduction

Avishay Katz, an accomplished inventor based in Westfield, NJ (US), is renowned for his significant contributions to the field of bonding technologies. With a remarkable portfolio of 11 patents, he has demonstrated a relentless pursuit of innovation, particularly in methods that enhance the efficiency and effectiveness of bonding processes.

Latest Patents

One of Katz's latest patents details a novel bonding scheme utilizing a Group VB metallic layer. This method focuses on bonding one body to another, such as a laser device to a submount, using a metallic layer made from Group VB metals, notably niobium. The innovative process involves sandwiching the metallic layer between a non-metallic layer and a solder layer created by an approximate Au-Sn eutectic layer. The Group VB layer can be formed at submount temperatures below 201°C, preferably under 125°C, and potentially even less than 101°C, with a thickness ranging from 0.05 μm to 0.2 μm.

Additionally, Katz has developed a method for etching a diamond body, such as a CVD diamond film, by immersing it in a molten or partially molten metal, like the rare earth metals lanthanum or cerium. This technique allows selective protection of surface portions during etching, enabling the resultant dies to be utilized as submounts for lasers with feedback capabilities.
