FormFactor vs Silicon Laboratories
Side-by-side comparison of AI visibility scores, market position, and capabilities
World's largest probe card maker; ~$850M revenue. MEMS-based and cantilever probe cards are essential for wafer-level electrical test before dicing for advanced SoCs and memory.
About
FormFactor was founded in 1993 in Livermore, California and has grown into the world's largest manufacturer of probe cards—precision electromechanical assemblies that contact wafer-level die during semiconductor manufacturing to perform electrical parametric and functional tests before the wafer is diced. Probe cards are a consumable in semiconductor production: each card handles millions of probe contacts before being replaced, creating a recurring revenue model.\n\nFormFactor serves foundries (TSMC, Samsung), IDMs (Intel, Samsung, Micron), and memory manufacturers (Hynix, NAND makers) with MEMS-based probe cards for leading-edge SoC and logic testing, high-density cantilever cards for memory testing, and vertical probe cards for high-power devices. As chips shrink to 3nm and 2nm nodes with tighter pad pitches and as 3D chiplet architectures multiply the number of electrical connections to test, probe card complexity and average selling prices are increasing.\n\nFormFactor reported approximately $850 million in annual revenue and benefits from the same AI chip investment cycle as Teradyne: AI GPU wafers (NVIDIA H100/H200/B200) require advanced probe cards for wafer sort. The company also provides systems for failure analysis and materials characterization through its Systems division. FormFactor's strong market position in advanced logic probe cards makes it a direct proxy for leading-edge semiconductor manufacturing volume.
Pure-play IoT chip company after divesting Infrastructure/Automotive; EFR32 wireless SoC family (Matter/Zigbee/BLE/Thread) leads smart home and industrial IoT markets.
About
Silicon Laboratories (Silabs) was founded in 1996 in Austin, Texas and initially built mixed-signal ICs for modem and broadcast applications before pivoting to become a pure-play IoT chip company. Following the 2021 divestiture of its Infrastructure & Automotive business to Skyworks Solutions for $2.75 billion, Silabs is 100% focused on wireless connectivity semiconductors for IoT applications.\n\nSilabs' EFR32 Wireless Gecko SoC family is a market leader in smart home connectivity, supporting Matter, Zigbee, Thread, Bluetooth Low Energy, Sub-GHz, and Wi-Fi standards. These chips power smart lights, thermostats, door locks, energy meters, industrial sensors, and medical monitoring devices. The company's Simplicity Studio software ecosystem and extensive protocol stack support give it a strong developer platform advantage, especially as the Matter smart home standard (backed by Apple, Google, Amazon) gains adoption.\n\nSilabs also provides energy harvesting solutions and ultra-low-power microcontrollers for battery-powered IoT devices. The company generated approximately $2 billion in annual revenue before the Infrastructure divestiture and is now growing its IoT-focused revenue base through increasing smart home and industrial IoT demand. Silabs operates a fabless model and partners with TSMC for advanced node production.
