STMicroelectronics is considering an expansion of its Crolles semiconductor fabrication facility in response to the rising demand for AI optics, as stated by its CEO. This strategic move comes as the company focuses on enhancing chip packaging capabilities through subcontractors, aiming to support its silicon photonics growth without facing capacity constraints in the next three years. Additionally, STMicroelectronics’ partnership with Amazon Web Services is expected to bolster its position in the evolving market for optical components in AI data centers, driven by the trend toward placing optical engines closer to processors.
Jean-Marc Chery: Jean-Marc Chery serves as chief executive officer of STMicroelectronics. He stated at a June 2026 BNP Paribas conference in Geneva that the company expects to decide on additional Crolles fab capacity by year-end to support silicon photonics growth tied to near-package optics for AI processors. Chery noted existing infrastructure already covers needs through early 2028 while highlighting subcontractor considerations in packaging.
Remi El-Ouazzane: Remi El-Ouazzane is an STMicroelectronics executive focused on the data center segment. He emphasized the company’s growth trajectory in silicon photonics, pointing to strategic customer engagements and backing from a leading hyperscaler. El-Ouazzane linked this positioning directly to the partnership with Amazon Web Services.
STMicroelectronics: STMicroelectronics is a Franco-Italian semiconductor company that designs and manufactures a wide range of chips for automotive, industrial, consumer, and communications applications. It operates a key 300-millimeter wafer fabrication plant in Crolles, France, as its main production site for silicon photonics technology used in optical connections. The company is evaluating further expansion of this facility to address accelerating demand from AI data centers.
Amazon Web Services: Amazon Web Services provides cloud infrastructure and services supporting large-scale AI and data center operations. It maintains a strategic partnership with STMicroelectronics to advance silicon photonics solutions for optical connectivity inside and between data centers. This relationship underpins STMicro’s expansion plans in the AI optics space.
