Multinational companies and homegrown startups are putting Chennai on the map in the semiconductor industry. 

Chennai’s growth in the sector is due in large part to engineering graduates from IIT Madras, which recently partnered with Purdue University to offer a dual-degree master’s program in semiconductors. And while most companies in Chennai focus on the design of semiconductors, government incentives and market demand might spur more chip manufacturing in Tamil Nadu. 

In the list below, we take a look at some of the top semiconductor companies in Chennai.

Semiconductor Companies in Chennai to Know

Polymatech, which was formed by its Japanese parent company in 2007, says it is the first Indian company to manufacture semiconductor chips. The Chennai-based company develops opto-semiconductor chips at its factory in Oragadam, an industrial suburb of Chennai, and in 2023 it purchased a second plant in Krishnagiri. The company plans to invest $1 billion by 2025 to expand its production from 300 million chips to 10 billion chips per year.

San Diego-based pSemi, formerly known as Peregrine Semiconductors, is a Murata-owned company that designs and manufactures semiconductors integrated into 5G and IoT applications. The company announced in 2021 that it would open a design facility in Chennai due to India’s smartphone manufacturing industry. Engineers at the new facility will design cellular radio frequency (RF) front-end modules, sensor systems-on-a-chip and power management integrated circuits (ICs).
