Lam Research intends to add more sensing capability and AI-driven analytics to its wafer fabrication tools to improve productivity and lower defect rates, the companys chief executive said. In an interview, Lam CEO Tim Archer described a multi-year strategic focus on equipping equipment with sensors that produce data AI systems can analyze to spot problems and inefficiencies earlier in production.
Archer said this work is aimed at enabling customers to produce more chips per wafer with fewer defects. Wafers are the dinner-plate-sized silicon disks on which raw chips are printed, and better early detection of process anomalies could translate into higher usable yields for chipmakers.
The comments came as Lam hosted a venture capital competition at its Fremont, California, headquarters. At the event the company awarded a $250,000 investment to Lightfinder, a Massachusetts Institute of Technology spinout. According to Lam, Lightfinder has reduced the size and cost of a previously standalone measurement tool so it can be integrated directly into an existing machine rather than requiring a separate process step.
Archer emphasized the value of richer data streams from both the equipment and the wafer. "The more data you collect from the machine itself, or from the wafer, the better your models can be about predicting whats happening and starting to really react to problems in the system," he said. "What AI is allowing us to do ... is basically identify conditions in the system that we didnt know were a problem before."
On geographic expansion, Archer confirmed that Lam plans to open an additional facility in the Phoenix area to support customers including Taiwan Semiconductor Manufacturing Co. He also said Lam will continue investing at its California headquarters, where it still conducts manufacturing work.
In December reports noted that Lam spent more than $45 million on a 148,000-square-foot building near TSMCs factories in the Phoenix area, though Archer said the company has not yet provided details about plans for that facility. "Clearly, we see Arizona as a place that we need to be from the standpoint of supporting customers," Archer said. "I think youll very soon see more investment coming here in the Fremont area."
Lam supplies tools to major chipmakers including Micron Technology and Taiwan Semiconductor Manufacturing Co. The companys stock has risen by more than 75 percent so far this year as demand for AI chips has driven customers to purchase additional equipment.
Key operational focuses described by Archer include deploying additional sensors on tools, expanding AI analytics to interpret sensor and wafer data, and integrating measurement capability into existing machines through investments in startups. The stated timeline for the sensor and AI work is the next two years.
