Other Materials
Specialty substrates for applications that demand unusual properties — ceramics, piezoelectric crystals, IR materials, diamond, and flexible polymers.
Overview
Beyond standard silicon and common compound semiconductors, many device technologies require specialty substrate materials with unique combinations of electrical, thermal, optical, or piezoelectric properties. Whether you're developing SAW filters on lithium niobate, high-power devices on diamond, or flexible electronics on polymer films, we source hard-to-find materials from qualified crystal growers and material suppliers worldwide.
