SPTS has a wide range of PVD module technologies to meet the demands of compound RF-IC and MMIC manufacturing. Typical applications include:

  • Frontside Au Interconnect
  • Thin Film Resistors (TFR)
  • Backside via seed
  • Bulk acoustic wave (BAW) electrodes & piezoelectric layers
  • Surface acoustic wave (SAW) electrode & encapsulation


Benefits of SPTS PVD for Compound Semiconductors RF-IC

  • Flexible, extendible hardware
  • Mainstream Si reliability
  • Wide range of materials experience
  • Continued support of ≤ 200 mm wafer sizes
  • Unique ESC, compatible with sapphire carriers without the need for a back-coat
