Amid the steadily rising discuss Moore’s Regulation of transistor scaling hitting the wall, Marvell co-founder and CEO Sehat Sutardja introduced the thought of modular chips (MoChi) on the Worldwide Strong State Circuits Convention (ISSCC) in 2015. This ultimately culminated into what’s now broadly often called chiplets.
He later mentioned the thought of those daisy-chain a number of chips with AMD’s CTO Mark Papermaster, who thought the title was too sophisticated, calling them chiplets. Sehat’s ardour and dedication to cobbling totally different items of silicon right into a single package deal ultimately led him to cofound the primary chiplet foundry Silicon Field in 2021.
Sehat Sutardja, co-founder of Marvell and Silicon Field and investor and backer of a number of semiconductor startups, handed away on 18 September 2024. He was often called one of many pioneers of the fashionable semiconductor business. “I’m a bit narrow-minded. I solely see issues by way of electronics,” he was quoted in a profile story, “Sehat Sutardja: An Engineering Marvell,” revealed in IEEE Spectrum in October 2010.
Born in a Chinese language household in Jakarta, Indonesia, in 1961, he was drawn to the wonders of electronics early in his childhood. Whereas in sixth grade, he visited his youthful brother Pantas Sutardja, who lived with their grandparents in Singapore. Throughout this time, he acquired maintain of Pantas’ hobbyists DIY books and magazines and was fascinated by the thought of constructing a Van de Graaff generator. The 2 siblings ended up creating a crude however functioning machine.
From Van de Graaff generator to storage chips
When again in Jakarta, Sehat began constructing a miniature model of the Van de Graaff generator. After some research at a bookstore, he found that the improved machine would require changing mechanical switches with transistors. That led him to a close-by radio store, and in a yr or so, he’d obtained a radio restore license.

Whereas taking part in with transistors, he usually encountered firm names corresponding to Fairchild, Nationwide Semiconductor, Motorola, and Texas Devices. These had been all U.S. firms, which led to his inclination towards finding out in america. A buddy of his brother was enrolled on the College of San Francisco, and that connection took him there in the summertime of 1980.
What occurred subsequent clearly reveals Sehat’s intimate bond with electronics. After disacovering that the college doesn’t have electrical engineering program, he moved to Iowa State College and earned his bachelor’s in electrical engineering in 1983. Then he moved to the College of California, Berkley, the place he accomplished his grasp’s in 1985 and Ph.D. in 1988 in electrical engineering and laptop science.
That’s the place he additionally met his spouse, Weili Dai, who was a pc science main. Sehat started his skilled profession as an analog circuit designer with two Bay Space firms: Micro Linear and Built-in Info Expertise. At Micro Linear, he labored on digital-to-analog converters (DACs) and different chips for laborious disk drives (HDDs).
Subsequent, at Built-in Info Expertise, he labored on circuits for digital video compression and decompression, a expertise that ended up in AT&T’s notorious VideoPhone. In the meantime, his spouse Weili wished them to begin their very own firm, so in 1995, they based Marvell Expertise Group together with Sehat’s brother Pantas Sutardja. The title Marvell got here from their quest to create “marvelous” issues; it ended with “el” following the names of profitable tech firms like Intel, Novell, and Nortel.
Beginning of Marvell
Pantas, who had not too long ago left IBM’s Almaden Analysis Middle, had labored on laborious drive expertise at IBM. That, mixed with Sehat’s stint at Micro Linear and experience in mixed-signal chips, led them to develop digital learn channels for laborious disk drives. At the moment, analog learn channels from firms like Infineon, STMicroelectronics, and TI relied on amplitude peaks to decode HDD information.
Then again, digital expertise might make the most of the newly arrived CMOS expertise scaling to outline bit patterns on a tough disk monitor. So, Marvell used high-speed sampling and DSP filtering to introduce digital learn channels that considerably elevated disk drive information densities. That put TI out of read-channel enterprise.

They’d working chips by Christmas 1995, and Seagate turned Marvell’s first buyer. Marvell has dominated the disk drive controller market since then. The timing was impeccable from two standpoints. First, the fabless design motion was simply taking off, and Marvell turned one of many early success tales within the rising fabless semiconductor enterprise mannequin.
Second, by adopting CMOS expertise for its debut chip for a tough disk drive, Marvell turned one of many early adopters and beneficiaries of the historic transition from bipolar to CMOS chip manufacturing. Marvell adopted the CMOS-centric strategy on different merchandise like Ethernet switches and transceivers to create quicker and extra energy savvy chips.
Nonetheless, Marvell and Sehat stored a comparatively low profile whereas laser targeted on the corporate’s product and expertise roadmaps. Sehat, often called humble and right down to earth, didn’t make splashes in commerce media like many different founders and CEOs of profitable chip firms.
Then, in 2016, Marvell’s intensely fairly world was hit by an accounting scandal. Although president and CEO Sutardja and his spouse, Dai, chief working officer, had been cleared of any monetary misconduct, the strain on gross sales groups to fulfill income targets led each Sutardja and Dai to go away their respective positions. Sutardja remained the chairman of the board.
The chiplets man
Within the aftermath of this accounting investigation, Sutardja and Dai remained extremely revered in semiconductor business circles. After turning a scrappy little startup right into a formidable semiconductor outfit, the husband-wife duo had engaged in over dozen startups, together with Alphawave and DreamBig.
Additionally they co-founded a specialised fab constructed round chiplet and superior packaging applied sciences. Silicon Field, after constructing a fab in Singapore, is establishing one other chiplet fab in Northen Italy to raised serve European chip firms.

Sehat’s deal with chiplets reveals his foresight on the way forward for semiconductors. To precise his relationship with semiconductor expertise and the way it stored him going, he as soon as mentioned, “I don’t know anything.”
