Zvi Or-Bach
Founder and CEO of MonolithIC 3D™Inc.
Zvi Or-Bach is the founder and CEO of MonolithIC 3D™ Inc.
Or-Bach is a world-recognized expert in monolithic 3D technologies, past chairman of the 3D track of the IEEE S3S Conference, and is active as an invited speaker and tutorial instructor in the US, Korea, and Japan. He is the author of four monolithic-3D-related chapters in NANO-CHIPS 2030 and a chapter in CHIPS 2020 Vol. II. For more information, see the Record of Invention.
At IEEE S3S 2017, Or-Bach published a landmark paper, "A 1,000x Improvement in Computer Systems by Bridging the Processor-Memory Gap," leveraging monolithic 3D integration on existing transistors and fab processes. His recent work on highly stackable charge-trap 3D DRAM received the Best Paper Award at IEEE TENCON 2025. Today MonolithIC 3D holds more than 400 issued US patents with over 350 pending, operates a patent licensing program, and conducts joint research programs with leading Korean universities.
Or-Bach is currently Chairman of the Board of Zeno Semiconductor. He has a history of innovative development in fast-turn ASICs spanning more than 20 years: his vision led to the first Structured ASIC architecture, the first single-via programmable array, and the first laser-based system for one-day gate-array customization.
Prior to founding MonolithIC 3D in 2009, Or-Bach founded eASIC in 1999 and served as its CEO for six years; eASIC was funded by leading investors including Vinod Khosla and KPCB and was acquired by Intel in 2018. Under his leadership, eASIC won EE Times' 2005 ACE Award for Ultimate Product of the Year (Logic and Programmable Logic) and the Innovator of the Year Award, and was named among EE Times' "Disruptors — the people, products and technologies changing the way we live, work and play." Earlier, Or-Bach founded Chip Express in 1989, serving as president and CEO for 10 years and growing it to $40M in revenue; Chip Express was acquired by GigOptix, later acquired by IDT.
Or-Bach received his B.Sc. (1975) cum laude in electrical engineering from the Technion — Israel Institute of Technology and his M.Sc. (1979) with distinction in computer science from the Weizmann Institute of Science. He is a named inventor on more than 550 issued US patents, with new patents issuing weekly.
