Tata PSMC Dholera Semiconductor Fab Crosses 50 Percent Construction Mark

Tata-PSMC Dholera Fab at 50 Percent Construction: First Indian Logic Silicon on Track for December 2026

India's most closely watched infrastructure project in the semiconductor sector, the Tata Electronics and Powerchip Semiconductor Manufacturing Corporation joint venture fab at Dholera Special Investment Region in Gujarat, has crossed the 50 percent construction completion mark. Site updates confirm that the structural foundation work is complete, the cleanroom building shell has been erected, and critical systems installation including cleanroom air handling units, ultra-high purity chemical distribution systems, and deionised water generation infrastructure is now underway. The facility remains on schedule to deliver first silicon by December 2026.

Facility Specifications and Technology Node

The Dholera fab is designed as a 300mm wafer fabrication facility with initial planned monthly capacity of 50,000 wafer starts. The technology portfolio is being established in partnership with PSMC and includes process nodes at 28nm, 40nm, 55nm, 90nm, and 110nm, covering a range from relatively advanced logic for connectivity and automotive chips down to mature nodes used in power management, display drivers, and industrial microcontrollers. The 28nm node at Dholera is particularly significant as it is the same node used in chips for automotive ADAS, smartphone power ICs, and mid-range IoT processors, positioning the facility to serve real commercial demand from day one rather than producing chips only for captive or government consumption.

Equipment Procurement and ASML Partnership

A critical enabler of the Dholera timeline is the strategic partnership signed with ASML in May 2026, under which the Dutch lithography equipment maker will supply immersion and deep ultraviolet lithography tools for the facility. Lithography equipment typically accounts for the largest single capital expenditure category in a semiconductor fab, and the long lead times for ASML systems make early commitment essential for any fab targeting a specific production date. With the ASML partnership in place, equipment delivery and installation planning for the Dholera fab is proceeding in parallel with construction, a standard practice for minimising total time from groundbreaking to first wafer that Tata Electronics is executing for the first time in Indian fab history.

Workforce and Training Readiness

Operating a 300mm semiconductor fab requires a highly trained workforce in specialised disciplines including process integration, equipment engineering, yield analysis, metrology, chemical mechanical planarisation, and lithography process control. Tata Electronics has been building this workforce through a combination of IIT Madras and IIT Bombay partnerships, PSMC-led training programmes in Taiwan for key Indian engineers, and MeitY-supported structured apprenticeship initiatives under Semicon 1.0. With the fab construction now past the halfway mark, the workforce readiness timeline is converging with the equipment installation schedule, which is a positive indicator for meeting the December 2026 first silicon target.

National Significance

First silicon from the Dholera fab will mark India's entry into the exclusive club of countries with domestic front-end wafer fabrication capability, a list currently dominated by the United States, Taiwan, South Korea, Japan, and China. Every chip produced at Dholera will be a concrete demonstration that India can manufacture semiconductor wafers on its own soil, transforming the India semiconductor story from a packaging and design narrative into a full-stack manufacturing proposition. The milestone is expected to generate strong investor interest in the second wave of fab projects that Semicon 2.0 is designed to catalyse, showing that India's first fab bet was not aspirational but operationally real.
