Case Study: Hitachi High-Tech achieves more reliable semiconductor equipment maintenance with GlobalLogic's Reliable AI

Hitachi High-Tech builds a zero-hallucination AI maintenance engine with GlobalLogic

Hitachi High-Tech faced the challenge of maintaining highly complex and expensive semiconductor manufacturing equipment. With rising equipment complexity and a shortage of expert field engineers, they needed a way to reliably transfer deep institutional knowledge locked in detailed manuals to technicians. Generative AI was considered, but the environment demanded a zero-hallucination solution where reliability was paramount. They partnered with vendor GlobalLogic to address this using their VelocityAI service offering with a core principle of Reliable AI.

GlobalLogic implemented a hybrid reasoning solution built on a curated knowledge base from equipment manuals. This system used deterministic logic and a set of scoped AI agents for planning, allocation, and execution to ensure every answer was traceable to source material, creating a zero-hallucination engine. The solution provides concrete benefits for technicians, including time savings and increased safety, and for the equipment, including lower error rates and prolonged lifespan. While quantified outcomes will follow broader deployment, the proof of concept developed by GlobalLogic successfully laid the foundation for a system deployable in high-stakes environments.
