Case Study: Hemlock Semiconductor boosts output, quality, and energy savings with Spotfire

Hemlock Semiconductor increases global competitiveness by optimizing output and lowering costs

Hemlock Semiconductor, a major polysilicon producer, faced challenges optimizing its complex, high-purity manufacturing process to reduce costs and remain competitive in a commoditized global market. The company needed to gain deeper insights from its vast operational data, which was trapped in silos, to improve quality, control energy consumption, and explore new business models. They turned to vendor TIBCO, utilizing its Spotfire analytics and Connected Intelligence platform.

TIBCO's solution provided real-time data visualization, analytics, and system integration, enabling Hemlock to proactively monitor and optimize production. This led to the detection of process anomalies, improved energy efficiency through peak power management, and more agile decision-making. The measurable results included significant monthly cost savings of approximately $300,000 from optimized energy use, along with enhanced product quality, yield optimization, and a foundational shift to a data-driven culture.
