He is recognized for being the all-time seventh most prolific inventor as measured by number of U.S. utility patents.
[3] The publication Kiplinger reports, "Sandhu developed a method of coating microchips with titanium without exposing the metal to oxygen, which would ruin the chips.
The publication also states that Gurtej earned an electrical engineering degree at the Indian Institute of Technology – Delhi in India and a physics PhD at the University of North Carolina at Chapel Hill.
They said his "pioneering achievements concerning patterning and materials integration have enabled the continuation of Moore’s Law for aggressive scaling of memory chips integral to consumer electronics products such as cell phones, digital cameras and solid-state drives for personal and cloud server computers."
Extreme device scaling was also made possible through his pitch-doubling process, which led to the first 3X-nm NAND flash memory.
