==Early life and education==
Gurtej Singh Sandhu was born on 24 October 1960 in [[London]] to Indian [[Sikhs|Sikh]] parents. Both of his parents were PhD graduates from the [[University of London]]. Sandhu was raised in [[Amritsar]], India, where his father was a chemistry professor at the [[Guru Nanak Dev University]].<ref>{{Cite news |title=The Amritsar Scientist Who Calmly Broke The Century-Old US Patent Record Of Thomas Edison |url=https://www.news18.com/viral/the-amritsar-scientist-who-calmly-broke-the-century-old-us-patent-record-of-thomas-edison-aa-ws-l-9508763.html |archive-url=http://web.archive.org/web/20250820231143/https://www.news18.com/viral/the-amritsar-scientist-who-calmly-broke-the-century-old-us-patent-record-of-thomas-edison-aa-ws-l-9508763.html |archive-date=2025-08-20 |access-date=2026-02-12 |work=News18 |language=en-US}}</ref>

Influenced by his parents, Sandhu earned a Master of Science (Honours) in Physics from Guru Nanak Dev University, followed by a Master of Technology in Electrical Engineering from the [[Indian Institute of Technology, Delhi]]. He moved to the United States, where he earned a Ph.D. in Physics from the [[University of North Carolina at Chapel Hill]], graduating in 1990.<ref name="FLOGEN" /><ref name="HT" /><ref name="IEEE" />

==Technical contributions==
Sandhu’s early breakthrough at Micron involved developing a titanium coating process for microchips that prevented oxygen exposure, a technique now widely adopted in memory-chip production.<ref name="Kiplinger">{{cite web|title=Patent Making: Suddenly It Clicks|url=https://www.kiplinger.com/article/business/T012-C000-S002-patent-making-suddenly-it-clicks.html|date=June 2008|archive-url=https://web.archive.org/web/20140529084605/http://www.kiplinger.com/article/business/T012-C000-S002-patent-making-suddenly-it-clicks.html|archive-date=29 May 2014}}</ref>

His innovations span several key processes in semiconductor manufacturing, including [[Atomic Layer Deposition]] (ALD) of high-κ films for [[Dynamic random-access memory|DRAM]], pitch-doubling techniques for [[NAND flash memory|NAND flash scaling]], and [[Chemical vapor deposition|CVD]] Ti/TiN processes still used in DRAM and NAND fabrication.<ref name="IEEE" /> These advancements have enabled the continuation of [[Moore’s Law]] for memory chips and have been foundational to advanced patterning and materials integration.

==Awards and recognition==
Sandhu received the [[IEEE Andrew S. Grove Award]] in 2018 for outstanding contributions to solid-state devices and technology, and is a [[Fellow of the IEEE]].<ref name="IEEE"/>
He has also been honored with a Distinguished Alumni Award from IIT Delhi.<ref name="HT"/>
As of 2024, he is recognized among the world’s top inventors for his extensive patent portfolio.<ref name="Justia"/>

==Personal life==
Sandhu resides in [[Boise]], [[Idaho]], and is known for his humility and mentorship of young engineers.

He enjoys sports such as basketball and table tennis, and emphasizes that innovation often extends beyond patents, with many breakthroughs retained as trade secrets.<ref name="FLOGEN" />
He is also active in philanthropy, supporting educational initiatives and contributing to thought leadership in semiconductor scaling through keynote talks and [[IEEE Spectrum]] interviews.<ref name="EandT">{{cite web|title=Gurtej Singh Sandhu|url=https://ethw.org/Gurtej_Singh_Sandhu}}</ref><ref name="IEEE" />
