L&T's Chip Arm Signs a Taiwan Pact to Build India's Power Semiconductors

An MoU aimed at the power inside AI data centres

On 9 July 2026, L&T Semiconductor Technologies (LTSCT), the fabless chip subsidiary of engineering conglomerate Larsen & Toubro, signed a memorandum of understanding with Taiwan-based Azuremoto Technologies to jointly develop silicon carbide (SiC) and other power-semiconductor products. The tie-up targets two fast-growing markets in particular: the power electronics that feed artificial-intelligence data centres, and the everyday power devices inside meters, air-conditioning and solar inverters.

It is a modest-sounding document — a framework, not a fab — but it points at a part of the chip world where India has almost no domestic presence, and where demand is climbing steeply.

Silicon carbide, and why it matters

Most chips are built on plain silicon. Silicon carbide belongs to a class of "wide-bandgap" materials that can handle higher voltages, higher temperatures and faster switching with far less energy wasted as heat. That makes SiC the material of choice for the power stages of electric vehicles, solar inverters, industrial drives and, increasingly, the enormous power-supply chains that keep AI server halls running.

As data centres pack in more GPUs, their electricity draw has become a first-order design problem, and SiC-based power supplies are one of the main levers for squeezing more compute out of every watt. That is the opportunity LTSCT and Azuremoto are aiming at.

Who does what

Under the agreement, the collaboration spans SiC MOSFETs, diodes and related modules for AI data-centre applications such as power supplies and server power architecture, alongside rectifiers and MOS-based power-semiconductor products for uses including energy-metering systems, HVAC power control and solar inverters.

The division of labour is clear. LTSCT will supply product roadmaps, technical specifications, application guidance and regulatory-compliance support — the design and engineering side. Azuremoto will lead market development, sales and customer-relationship management within agreed territories. In effect, LTSCT brings the product definition and India-market access; Azuremoto brings a route to customers and its own power-device experience.

A rung on India's semiconductor ladder

LTSCT is one of the more closely watched entrants in India's chip push. Rather than chasing leading-edge logic fabs, it has staked out power and mixed-signal devices — a segment where the process nodes are mature, the capital bar is lower, and India's import dependence is near-total. Power semiconductors quietly sit inside almost every electric vehicle, charger, inverter and appliance the country makes, and almost all of them come from abroad.

An MoU does not by itself produce a single wafer, and neither company disclosed volumes, timelines or where the parts would ultimately be fabricated. But the deal sketches the shape of the bet: pair Indian product engineering with an established Taiwanese partner, aim at the power electronics that both the energy transition and the AI build-out are pulling into demand, and try to convert India from a pure importer of power chips into a designer of them.
