L&T Semiconductor Partners with Foxconn to Develop High-Voltage Semiconductor Wafers

According to reports, L&T Semiconductor Technologies and Hon Young Semiconductor, a subsidiary of contract maker Foxconn, inked a long-term agreement on 14 October to collaborate on the development of high-voltage semiconductor wafers. According to the Economic Times, the two businesses would create wafers for industrial and automotive applications with voltage ranges between 650V and 3,300V.

The two will also “cooperate” to guarantee “wafer performance, quality, and scalability,” according to the article. According to a statement from the firm, the collaboration makes use of LTSCT’s integration skills and domain knowledge of automotive and industrial power solutions, as well as HYS’s extensive experience in wafer fabrication.

According to reports, the collaboration will also make it possible for L&T Semiconductor to design and manufacture wafers specifically for power components using Hon Young Semiconductor’s facilities in Taiwan.

L&T Semiconductor Technologies and its Operations

L&T Semiconductor Technologies is a fully-owned subsidiary of Larsen & Toubro (L&T), an engineering, procurement, and construction (EPC) firm. The company that manufactures fabless semiconductors creates and supplies smart gadgets to clients worldwide. It seeks to develop a semiconductor portfolio for automotive, industrial, energy, and telecommunications sectors that includes power, analogue, mixed signal, and radio frequency products.

This latest venture is L&T’s most recent attempt to establish a presence in the rapidly expanding Indian semiconductor market. In June, the domestic company partnered with Kaynes Semicon to pay INR 118.32 Cr to acquire the power modules division of Fujitsu General Electronics, a Japanese company.

In order to design cutting-edge CPUs, L&T Semiconductor Technologies also inked a research and development (R&D) agreement with tech giant IBM in September of last year. The company had previously announced in July 2024 that it will pay INR 183 Cr to acquire a 100% share in semiconductor design startup SiliConch Systems.

Foxconn Aggressively Expanding its Network in India

Foxconn has been rapidly expanding its business in India. The business and HCL stated earlier this year that they would form a joint venture (JV) to establish an OSAT plant in Noida, Uttar Pradesh, to produce chips for computers, mobile phones, and cars. In the meantime, Foxconn’s primary business is the production of smartphones.

The Taiwanese corporation has committed INR 15,000 Cr to expand its activities in the state, according to a statement made by Tamil Nadu Industries Minister TRB Rajaa just one day ago. This came after Foxconn’s plan to invest $2.2 billion in the US and India was approved by Taiwan’s Ministry of Economic Affairs.

Nevertheless, Foxconn is among India’s biggest contract iPhone makers. The business shipped $3.2 billion worth of iPhones from India to the US between March and May. In 2025, it intends to produce 25–30 million iPhones in India.
