The revised ISO 9001 quality management system provides guidelines to help materials providers achieve stringent purity and process control requirements in a structured and consistent manner.
One tool Linde uses to ensure that their suppliers meet meticulous quality requirements is Statistical Quality Control (SQC): the use of statistical methods to monitor and control a process.
IC technology step changes are driving electronic materials purity and analytical requirements. The bottom line? Materials suppliers must reduce variability and tighten control limits to help fabs meet market demands for more complex devices.
Technology changes in semiconductor processing and demands for higher-purity and better-characterized electronic materials have driven the need for advanced analytical metrology.
A TLIMS/SQC Process Control System is capable of real-time monitoring and reporting, across the supply chain, for the production of specialty gases.
