What SemiProbe does
SemiProbe, Inc. is a privately held semiconductor capital equipment company founded in 2006 and headquartered in Winooski, Vermont. The company designs, manufactures, and sells modular wafer probing systems used to electrically test semiconductor devices at the wafer, die, partial-wafer, and packaged-part level. Its core platform is the Probe System for Life (PS4L), a patented adaptive architecture in which all major components (bases, stages, chucks, microscope mounts, manipulators, optics) are interchangeable, configurable, and field upgradable, allowing customers to move from manual to semiautomatic to fully automatic configurations and from single-sided to double-sided systems without replacing the base platform. The portfolio spans the PS4L Manual/Semiautomatic/Fully Automatic families (M, SA, FA-4/6/8/12 for 100-300mm wafers), the entry-level Lab Assistant and mini-PS4L sub-brands for small-footprint applications, the PILOT control software suite, and an extensive accessories catalog (manipulators, probe tips, thermal chucks, dark boxes, vibration isolation, probe card holders, packaged-part holders).
SemiProbe serves three primary vertical segments: universities and research institutions conducting semiconductor and physics R&D, government research labs performing device characterization and reliability testing, and high-technology companies developing MEMS, RF/microwave, high-power, optoelectronic, and magnetic devices. The company employs 1-10 people and operates from a single Vermont facility, selling direct via phone, email, discovery calls, and an online accessories shop, with a financing partnership through North Star Leasing for purchases above $10,000. Revenue is generated through hardware sales of probing systems, accessories and consumables, customized turnkey solutions, and PILOT software licensing. The installed base of hundreds of systems spans five continents across North America, Europe, Asia Pacific, and the Middle East, with end customers in the USA, Canada, Germany, Denmark, Finland, China, Taiwan, Korea, Singapore, and Saudi Arabia.

SemiProbe product offering
Product offeringCore offering
SemiProbe designs and manufactures modular wafer probing, inspection, and test systems based on its patented Probe System for Life (PS4L) architecture. The company sells manual, semiautomatic, and fully automatic probe stations supporting wafer sizes from 50mm to 300mm, along with accessories (manipulators, probe tips, chucks, holders) and the PILOT control software suite for semiconductor device characterization in MEMS, high-frequency, high-power, optoelectronics, vacuum, and magnetic applications.
Product overview
SemiProbe offers the Probe System for Life (PS4L) as its core modular probing platform, featuring interchangeable and field-upgradeable components. The PS4L family includes Manual Systems (M-4/6/8/12 for 100-300mm wafers), Semiautomatic Systems (SA-4/6/8/12 with programmable stages), and Fully Automatic Systems (FA-4/6/8/12 with robotic material handling). Supporting products include the Lab Assistant sub-brand for small-footprint entry-level systems, mini-PS4L for compact testing, and the PILOT Software Suite for system control and instrumentation communication. A comprehensive line of accessories encompasses manipulators, probe tips, probe card holders, packaged part holders, wafer chucks, thermal chucks, dark boxes, and vibration isolation tables. All components are designed to work interchangeably within the PS4L architecture, enabling field upgrades and application-specific configurations.

SemiProbe competitors and assessment
Company assessmentBroad incumbents
- FormFactor: FormFactor (including legacy Cascade Microtech) is the dominant supplier of wafer probers for both R&D and production test. Directly comparable product line (CM300, Summit series) and overlapping customer base in universities, foundries, and IDMs. Far broader portfolio but the most direct competitor in SemiProbe's R&D and engineering-probing niche.
- Keysight Technologies: Keysight supplies semiconductor test instrumentation (B1500A, 4200A) and integrated prober solutions. SemiProbe's PILOT software integrates with Keysight instrumentation, making Keysight both a partner and a competitor as it expands its own prober offerings (e.g., via the acquired e-beam and parametric test lines).
- Tokyo Seimitsu (Accretech): Accretech, the semiconductor equipment arm of Tokyo Seimitsu, manufactures wafer probers alongside prober and dicing equipment. Competes with SemiProbe in production and R&D probing for memory and logic devices, particularly in the Japanese and broader Asian markets.
Direct peers
- SUSS MicroTec: SUSS MicroTec is the wafer prober specialist where SemiProbe's three founders worked for a combined 35 years. Direct competitor across manual, semi-automatic, and fully automatic probers (PM8, PA300, etc.) serving MEMS, RF, and optoelectronics applications. SUSS's product line is the most direct technical and commercial overlap with PS4L.
- MPI Corporation: Taiwan-based MPI Corporation manufactures wafer probers and test instrumentation with direct overlap to SemiProbe's RF, high-power, and MEMS product lines. Strong in the Asian semiconductor market and a frequent competitor for university and IDM RF testing accounts.
- Signatone: Signatone is a US-based wafer prober manufacturer with comparable manual and semi-automatic probe systems serving R&D and production customers. Directly comparable in product line, scale, and customer segment focus.
Regional players
- Micronics Japan (MJC): Micronics Japan manufactures wafer probers primarily for the Japanese semiconductor market, with a focus on memory and logic test. Comparable product line in manual and semi-automatic probers, though with limited US market presence.
Emerging players
- Wentworth Laboratories: Wentworth Laboratories manufactures probe stations and probe cards for wafer-level test, with focus on emerging applications including photonics and MEMS. Comparable niche positioning and customer base, though with stronger UK and European presence.
- Onto Innovation: Onto Innovation (merger of Nanometrics and Rudolph Technologies) supplies macro and micro defect inspection as well as metrology equipment used in adjacent wafer-level test workflows. Comparable customer base in fabs and R&D labs, with some product overlap in inspection (overlapping with SemiProbe's inspection offerings).
Others
- Lake Shore Cryotronics: Lake Shore supplies cryogenic and temperature-controlled probe stations and Hall effect measurement systems. Comparable in serving low-temperature and physics-research customers, with adjacent (not directly competing) probe technology for quantum and magnetics applications.
