This case study details how Hemlock Semiconductor Operations used Spotfire to optimize polysilicon manufacturing in a highly competitive, commodity-driven market. The company needed to reduce costs, improve quality, and conserve energy while managing complex production processes. Spotfire enabled real-time visibility into manufacturing variables, anomaly detection, and process optimization. Hemlock reduced energy costs by approximately $300,000 per month, improved yield, and enhanced quality control. The platform also supported sustainability initiatives, predictive maintenance, and integration with ERP systems. The solution helped shift Hemlock from reactive to proactive operations and reinforced its leadership position in the global semiconductor supply chain.
