History

yieldWerx was founded in 2010 in Plano, Texas to address increasing complexity in semiconductor product development and manufacturing, particularly as advanced device architectures, heterogeneous integration, and globalized supply chains generated large volumes of fragmented manufacturing data. yieldWerx developed a centralized yield management platform designed to unify data across fab, assembly, test, inspection, and advanced packaging environments into a single analytics framework.

Since its founding, yieldWerx has expanded its platform capabilities to support applications in advanced packaging (2.5D/3D and chiplets), silicon photonics, MicroLED and display technologies, AI and high-performance computing devices, and high-reliability semiconductor manufacturing. The platform is designed to enable cross-domain data correlation, large-scale data processing, spatial analytics, and digital-thread traceability across multi-stage manufacturing ecosystems, supporting yield ramp, excursion analysis, and ongoing process optimization.
