Minimize wafer contamination while boosting quality and yield

Overview

The Infosys High Tech practice helps manufacturers of microprocessors, Very Large Scale Integration (VLSI) circuits and semiconductor devices achieve sustainability goals. Our Environment, Health and Safety (EHS) management solutions minimize the carbon footprint, while boosting quality and throughput. We assess risks associated with emissions, usage of chemicals, energy consumption, and safety across the value chain, including design, manufacturing, use, and disposal of products. In addition, we undertake root cause analysis to identify safety, compliance and yield issues.

Infosys implements automated systems for inter-bay and intra-bay material movement. It minimizes the risk of wafer micro-contamination due to the presence of operators in clean rooms and damage due to mishandling at the foundry. We reconfigure process bays and floor layouts to eliminate contamination. In addition, we integrate automated material handling solutions with fabrication control systems, which maximizes process tool utilization and ensures operator safety. Further, safe passage of open as well as sealed wafer lots rationalizes inventory and inter-process storage costs.

Infosys experts align sustainability programs with regulations for the protection of semiconductor fabrication facilities and the workforce. We ensure compliance with guidelines and standards of the World Semiconductor Council (WSC) and Semiconductor Equipment and Materials International (SEMI) for electrical and production equipment, process liquid heating systems, exhaust ventilation, emergency shutdown, and hazard warnings, among other safety considerations. Our analytical solutions improve energy efficiency by predicting changes in operating conditions and equipment maintenance requirements. Significantly, our knowledge management systems enable ‘green’ chemistry and promote recycling initiatives.
