Tower Semiconductor Ltd. (TSEM) kicked off the week with an interesting announcement, even if the stock couldn't decide how excited it should be about the news. The company revealed a strategic collaboration with LightIC Technologies to manufacture silicon photonics-based Frequency-Modulated Continuous-Wave (FMCW) LiDAR sensors for automotive, robotics, and what's being called "Physical AI" applications.
The stock popped initially on the news, then gave up those gains and drifted lower as the day progressed. Market enthusiasm can be fickle like that.
Here's what the partnership actually involves: Tower will use its mature silicon photonics platform to manufacture LightIC's Lark long-range automotive LiDAR and FR60 compact LiDAR products. The technology extends silicon photonics manufacturing, which has already found widespread adoption in AI data-center networking, into sensing applications that need tightly integrated optical functionality including coherent ranging and instantaneous velocity detection.
The LiDAR Market Is Growing Fast
The timing makes sense when you look at the market trajectory. Research from Yole Group projects the global automotive LiDAR market will grow from $859 million in 2024 to $3.6 billion by 2030, which works out to a 24% compound annual growth rate. That's the kind of expansion that gets manufacturers interested. Yole also estimates the broader LiDAR market across all applications will hit $6.3 billion by 2027 as adoption spreads into industrial automation, smart infrastructure, and robotics.
Tower noted that the scaling of AI networking has accelerated silicon photonics process maturity and manufacturability, essentially creating a ready-made foundation for deploying the technology in automotive and sensing-driven Physical AI systems. In other words, the infrastructure work done for one market is now paying dividends in another.
From Lab to Road
"We are excited to expand our silicon photonics market beyond that of AI infrastructure into new sensing applications," said Dr. Ed Preisler, vice president and general manager of Tower Semiconductor's RF Business Unit, highlighting opportunities in robotics, Physical AI, and automotive markets.
LightIC CEO and co-founder Jie Sun emphasized that Tower's platform enables complex coherent LiDAR optical functions to be integrated directly into silicon on a scalable manufacturing process, supporting product qualification and long-term production needs.
The ultimate goal is improving size, weight, power consumption, and cost—the classic engineering quartet—to help transition velocity-aware 4D FMCW LiDAR from advanced development stages into real-world automotive deployment. That's the progression that matters for commercial viability.
TSEM Price Action: Tower Semiconductor shares were down 1.44% at $119.99 at the time of publication on Monday, according to market data.
