The Indian company described as aiming to become the “TSMC of design” was LogicFab Ltd., a Delhi-based semiconductor design-services startup. In 2007, it offered outsourced chip-design work—not wafer manufacturing—and its interim CEO, Rahul Sud, framed its ambition as a way for chip companies to share the cost of specialist engineering.
What was LogicFab?
EE Times reported on 3 May 2007 that LogicFab had been formed in mid-2006 by semiconductor veteran Rahul Sud and others. Sud was serving as interim CEO. His previous roles included work at Inmos, Lattice Semiconductor and STMicroelectronics.
LogicFab provided semiconductor design services. The report said it was working at 90-nanometer and 65-nanometer process nodes and was profitable at the time. Its work included digital design, with analog and mixed-signal design also within its intended scope.
Was it a chip manufacturer like TSMC?
No. TSMC manufactures wafers for customers; LogicFab was a design house offering engineering services. Its “TSMC of design” description was an analogy about outsourcing and scale, not a claim that LogicFab owned or operated a semiconductor fab.

Sud argued that the economics of chip design were reaching a point where some companies could not justify building every design capability in-house. A specialist provider could instead assemble engineering capacity and serve multiple customers. That was the business rationale he presented in 2007, rather than evidence that LogicFab had become an industry-scale counterpart to TSMC.
What did “the TSMC of design” mean?
Sud compared the proposed model with TSMC’s foundry business. In the EE Times report, he said TSMC emerged in 1987 as the cost of building a wafer fab crossed a threshold he put at $500 million. He argued that individual chip design had reached a comparable outsourcing threshold of $50 million.

Those dollar amounts were Sud’s 2007 estimates and analogy, not independently established current cost benchmarks. His point was that high fixed costs could encourage companies to outsource a specialist function rather than maintain the entire capability themselves.
To convey the scale he imagined, Sud said, “Imagine a company with 10,000 design engineers.” That was an illustration of ambition, not a reported LogicFab headcount.

Did LogicFab go public?
Sud told EE Times that LogicFab might move toward an IPO “in about three years.” The report records a possible plan made in 2007; it does not establish that the IPO occurred. It also does not establish LogicFab’s present-day operating status, so neither the planned listing nor the company’s current status should be treated as confirmed.
