PSMC in the Dholera fab ecosystem
Powerchip Semiconductor Manufacturing Corporation, known as PSMC, is a Taiwanese foundry that is the process-technology partner for the Tata Electronics fab at Dholera. This is a durable, confirmed relationship in our sources: the Union Cabinet approved the Tata fab with PSMC on 29 February 2024 under the India Semiconductor Mission. PSMC brings the mature and specialty node recipes and manufacturing know-how that let a first-time Indian fab operator start production.

Who PSMC is
Powerchip Semiconductor Manufacturing Corporation is a semiconductor foundry headquartered in Hsinchu, Taiwan. A foundry manufactures chips designed by other companies, and PSMC specialises in mature and specialty process nodes rather than the bleeding edge. Its portfolio covers logic, memory and specialty products such as power-management integrated circuits, display driver ICs and microcontrollers, which are exactly the product families associated with the Dholera fab in the fact pack. PSMC's value to a new entrant is not only its wafer capacity but its accumulated process knowledge: the detailed recipes, equipment settings and yield-learning that turn a cleanroom full of tools into a working production line. Taiwan built its semiconductor strength over decades, and technology-transfer partnerships like this one are a recognised route for new manufacturing nations to compress that learning curve. For India's first major commercial logic fab, having an established foundry as the technology partner is a core part of the project's credibility.
The confirmed Dholera link
PSMC's role at Dholera is confirmed and durable in our sources. Per the fact pack, the Union Cabinet approved the Tata Electronics fab, built with PSMC, on 29 February 2024 under the India Semiconductor Mission. The operating entity is Tata Semiconductor Manufacturing Private Limited, the investment is stated at Rs 91,000 crore, roughly US$11 billion, with the PIB Fiscal Support Agreement citing Rs 91,526 crore, and the India Semiconductor Mission covers 50 percent of eligible cost. The fab is a 300mm plant with planned capacity up to 50,000 wafers per month at nodes of 28, 40, 55, 90 and 110 nm. PSMC is named as the technology partner that provides the process technology for these mature and specialty nodes. This makes PSMC, alongside ASML, one of only two fab supplier relationships firmly confirmed for Dholera in our sources. The approvals, investment and capacity figures are durable; the build status and first-chip timing are targets, covered below.
What a technology partner provides
In a technology-transfer model, the partner licenses and helps install a proven process flow so the new fab does not have to invent its recipes from scratch. That includes the exact sequence of deposition, lithography, etch, implant, cleaning and metrology steps for each node, the equipment specifications those steps require, and the engineering support to bring yields up to commercial levels. PSMC's mature and specialty nodes are well suited to the products the Dholera fab targets, because power-management chips, display drivers and microcontrollers do not need the smallest transistors, they need reliability, cost efficiency and steady supply. Per the fact pack, Tata Electronics has indicated the plan was always to start with 55nm and 90nm, followed by 28nm, so the first chips will be at a mature node. A technology partner is central to hitting that plan, because the difference between a fab that runs and one that stalls is often the depth of transferred process knowledge and the speed of yield learning.
Build status and honest caveats
The approvals and investment are durable facts, but the production status is a target and should be read as such. Per the fact pack and v13 refresh, the fab broke ground in March 2024 and, by mid-2026, major structural and civil work is reported complete with cleanroom fit-out and machinery move-in underway, a step past the roughly 50 percent civil figure current in April and May 2026. First silicon or trial production is targeted around December 2026, and commercial-scale production is reported for mid-2028. No source confirms that a chip has been produced yet. Some coverage, such as Digitimes in April 2026, also reported leadership and engineering hurdles, which we note as a reported risk rather than a fact. The honest summary is that PSMC is a confirmed technology partner on a real, funded and under-construction fab, with production still ahead and its timing described in targets, not achievements.
