What Invantest does
Invantest, Inc. is a private San Jose-based semiconductor test-software vendor founded in 1994 (spun out as an independent company from KLA-Tencor in 2002) that sells real-time "intelligent" cell controller systems to wafer sort and final test operations. Its platform centers on the Navigator Floor Controller, an offline editor and server system that defines equipment setups and device profiles, and the Integrator family of cell controllers that run at each test cell: igWT (wafer sort), igFT (final test, with patented US Patents 7,835,881 and 8,185,337 covering Inline Retest), igMon (cross-cell monitoring), igOps (OEE tracking), and igDF (real-time data streaming with API). On top of the cell-controller layer, Invantest ships web dashboards (Production Dashboard, Virtual Test Floor, Floor Monitor, Efficiency Analyzer, Wafer Analyzer) and standalone analyzers (Lot Analyzer, Retest Analyzer) for yield, retest, and equipment efficiency analytics. Customers are semiconductor manufacturers across three primary verticals: OSATs (test subcontractors), IDMs, and fabless companies, with the company's stated quantifiable outcomes including 10% yield improvement, 20% OEE improvement, and 10% gross margin gains on deployed systems.

Invantest product offering
Product offeringCore offering
Invantest develops and licenses intelligent cell controller software systems for semiconductor wafer sort and final test operations. Its core platform, the Navigator Floor Controller paired with the Integrator cell controller family (igWT, igFT, igMon, igOps, igDF), provides real-time, mathematical process control that automates retest, standardizes operations, and measures overall equipment efficiency for OSATs, IDMs, and fabless semiconductor companies.
Product overview
Invantest offers a platform-plus-modules architecture for semiconductor testing. The core platform consists of cell controllers: Navigator Floor Controller serves as the central offline editor and server system, while Integrator cell controllers (WaferTest, FinalTest, Monitor, Ops, DataFlow) run at each test cell. These are complemented by web-based dashboard applications (Production DashBoard, Virtual Test Floor, Floor Monitor, Efficiency Analyzer, Wafer Analyzer) and standalone client applications (Lot Analyzer, Retest Analyzer). The system serves OSATs (test subcontractors), IDMs (integrated device manufacturers), and fabless semiconductor companies for wafer sort and final test operations.

Invantest partnerships and signals
Strategic signalPartnerships
Two partnerships are on record, tiered core.
- KLA-TencorcoreInvantest originated from a joint development program with KLA-Tencor and TEL (Tokyo Electron). This partnership produced the Integrator cell controller for wafer sort coupled with a Navigator floor controller. In 1994, KLA-Tencor and TEL customers used this technology to simplify, optimize, and improve quality of production testing at wafer sort. In 2002, KLA-Tencor spun-off its Integrator development group to become Invantest Inc.

Invantest competitors and assessment
Company assessmentDirect peers
- yieldHUB: yieldHUB offers test data analytics and yield management for semiconductor test, helping IDMs, fabless, and OSATs analyze STDF data to improve yield and throughput. Comparable to Invantest's Wafer Analyzer, Lot Analyzer, and Retest Analyzer products, though more analytics-focused than real-time control.
- PDF Solutions: PDF Solutions provides yield management, test data analytics, and process control software for semiconductor manufacturing. Like Invantest, it sells enterprise software to IDMs, foundries, and OSATs to improve yield, throughput, and equipment efficiency across wafer sort and final test.
Emerging players
- Tignis: Tignis provides AI-based process control for semiconductor manufacturing, including equipment efficiency and yield analytics. It overlaps with Invantest's OEE and Efficiency Analyzer capabilities but with a newer, AI-driven positioning targeting similar fabless/OSAT/IDM buyers.
- proteanTecs: proteanTecs provides chip telemetry and analytics for in-field and production test monitoring. It is comparable to Invantest in addressing test data visibility and yield improvement, with a differentiated chip-internal telemetry approach.
Broad incumbents
- Teradyne: Teradyne is a leading automatic test equipment (ATE) vendor whose UltraFlex and other tester platforms include integrated station/cell controller software. It overlaps with Invantest by offering test-floor orchestration bundled with the tester, competing head-to-head for the cell-controller budget at IDM and OSAT customers.
- Cohu: Cohu supplies semiconductor test handlers, interface solutions, and tester-related software. It competes with Invantest at the test-cell level by offering integrated handler-plus-controller solutions for OSATs and IDMs in final test.
- Advantest: Advantest is a global ATE leader whose V93000 and T2000 tester families ship with cell controller software. Comparable to Invantest as a tester-side station controller provider, though embedded in a much broader tester-and-handler portfolio.
- OptimalPlus (now part of Thermo Fisher Scientific): OptimalPlus, acquired by Thermo Fisher, historically provided real-time test analytics and yield management for semiconductor manufacturing. It is comparable to Invantest in serving OSATs and IDMs with data-driven yield and throughput improvement, now embedded within Thermo Fisher's broader analytical instruments portfolio.
- Siemens EDA (Tessent): Siemens EDA's Tessent division supplies DFT and silicon test software used by fabless and IDM customers alongside production test flows. While more upstream in the test flow than Invantest, it competes for the test-software budget across overlapping semiconductor customers.
- Onto Innovation: Onto Innovation provides process control, yield management, and metrology for advanced semiconductor nodes. It overlaps with Invantest's yield and OEE value proposition for fabs and OSATs, particularly at advanced packaging and wafer sort stages.
