Case Study: Amkor achieves significant manufacturing efficiency and cost savings with TIBCO Software (Spotfire DecisionSite)

Amkor achieves an industry edge by using TIBCO Spotfire to significantly improve manufacturing efficiency

Amkor Technology’s 120,000‑sq‑ft Iwate factory, a leading contract semiconductor assembly and test center for Japanese customers, faced intense cost and efficiency pressure across manufacturing, inventory and workforce areas. The plant needed faster, more accurate front‑line decision making to track product performance against hundreds of process, equipment, operator and material variables and to improve material balance, throughput and tool utilization.

Amkor deployed Spotfire DecisionSite visual, interactive analytics across inventory, manufacturing and HR to pinpoint root causes, optimize raw‑material inventory and monitor equipment and operator performance. The initiative boosted throughput without harming quality, cut obsolete inventory by 10–15% in three months, halved daily process tool time, reduced required tool sets by over 40% for key processes, and cut defect density on a critical product by 50%, while enabling clearer training and faster corrective action.
