ToolTrack MES: Your Semiconductor Manufacturing Solution

Semiconductor manufacturers live and die by yield — and yield management demands lot-level traceability, real-time process control data, and the ability to pinpoint exactly where and why excursions happen. Most enterprise MES platforms were built for high-volume commodity fabs and carry price tags to match. ToolTrack MES was built for the rest of the industry: mixed-product shops, MEMS, compound semiconductors, and advanced packaging operations that need die-level genealogy, tool scheduling, and SPC without a seven-figure implementation. We track wafer lots from bare wafer through final test, capturing parametric data at every step so your engineers can correlate process parameters to yield outcomes — not sort through paper travelers after a scrapped run.

Pitfalls of Paper Travelers

Paper travelers can't keep up with the pace of a modern fab. When a lot goes on hold, who knows which operations were completed and which were not? When a process excursion surfaces during electrical test, can you pull the full process history for every affected lot in minutes? With ToolTrack MES, every operation — etch, deposition, lithography, inspection, test — is recorded in real time against the lot. SPC rules fire automatically on parametric data, routing out-of-control lots for engineer review before they advance further down the line. The result is faster root-cause analysis, tighter process windows, and fewer surprises at wafer sort.

Why Chain Reaction Systems?

Chain Reaction Systems was founded by engineers who spent years on the shop floor of semiconductor and electronics manufacturers — not by enterprise software vendors. That experience is baked into ToolTrack. The platform handles the complexity of multi-step semiconductor flows: reentrant routing, split-and-merge lot processing, tool qualification tracking, and mask revision control. Unlimited user licensing means your process engineers, equipment technicians, and QA team all have access without per-seat negotiations. And because ToolTrack is metadata-driven, new product flows and process changes go live the same day — no code deployments, no re-validation of the MES itself.

How Does Chain Reaction Systems Do This?

ToolTrack's metadata-driven architecture means your process engineers configure the system — not a development team on a six-month statement of work. Route steps, data collection fields, SPC limits, hold codes, and approval workflows are all defined through the UI, not source code. Changes deploy instantly across all users and facilities with no downtime and no re-certification of the application.

The platform runs as a modern web application, accessible from any browser or mobile device on the factory floor. Multiple facilities share a single instance with independent product flows, while corporate-level reporting aggregates across all sites in real time. ToolTrack scales from a single-product pilot line to a multi-site operation without a platform change — or a renegotiated contract.

ToolTrack MES Benefits

  • Full lot genealogy and process history — pull the complete record for any affected lot in minutes, not hours of paper hunting.
  • SPC on parametric data fires automatically, routing out-of-control lots for engineer review before they advance further down the line.
  • Reentrant routing and split/merge lot processing handled natively — no workarounds for complex multi-step semiconductor flows.
  • Equipment qualification and PM tracking keeps your tools in spec and your uptime high.
  • NPI pilot runs are isolated from production so new product introduction doesn't disrupt your running lots.
  • Multi-site visibility under one instance — corporate reporting aggregates across all facilities in real time.
  • Manage equipment utilization, reducing scrap and increasing yields.
  • Shorten New Product Introduction (NPI) times by isolating pilot runs and providing intuitive access to quality monitoring data.
  • Maximize resources through controlled training & certification.
