FAQs: Quality

What is manufacturing recipe management software?

A recipe in manufacturing refers to the set of instructions for how a particular piece of equipment is going to process material. Recipe management software helps manage the potentially thousands of recipes in any given semiconductor factory.

Recipe management systems can reduce errors, improve efficiency, increase wafer output and provide traceability. They do so by storing the recipes in a secure, central repository and providing a means to review recipe differences, duplicates, and consolidations. It also generates the data needed for certification and audit readiness.

Managing thousands of recipes is a fundamental requirement of recipe management. Today’s recipe management systems must accommodate individual user organization preferences and provide flexible configuration options. They also should maintain recipes in a secure repository with redundancy and version control, reduce misprocessing by controlling equipment constants and recipe parameter values, and validate runtime recipes against recipe specifications to minimize rework and scrap.
Statistical process control (SPC) tools can help manufacturers move from a detection-based quality control method to a prevention-based one. They can minimize problems with process or quality by identifying them early, recommending actions to prevent or correct issues and providing information necessary to develop process improvement strategies.

SmartFactory SPC processes parameters in real-time and analyzes production data to identify process nonconformities. It does so by validating whether specifications are within limits, identifying suspect processing trends, and warning the staff when a process nonconformity is identified. Additionally, SmartFactory SPC helps foster a culture of continuous improvement by providing vital feedback about production processes to the manufacturing staff in real-time.
