TIBCO Success Story: Hemlock Semiconductor On a daily basis, everyone who uses modern methods to stay connected depends on quality polysilicon. Polycrystalline silicon, or polysilicon, is the primary raw material for the semiconductor and solar industries. It is used to create silicon wafers and other substrates for building a wide range of devices that people use every day, including smartwatches, cell phones, tablets, computers, Internet of Things devices, solar cells, and many others. Polysilicon is produced through a high-level chemical purification process that involves the distillation of compounds that decompose into silicon at extreme temperatures. Traditionally, polysilicon for electronic products requires impurity levels of less than one part per billion (ppb), though
