The basis for this development is the firm belief that next-generation devices will be built on engineered substrates to meet the ever-increasing demands of performance, power consumption, and heat dissipation.


  • SOI (silicon on insulator)
    Used to reduce device voltage operation and power consumption to improve device speed.
  • DSB (direct silicon bond)
    Improved device mobility in CMOS circuitry by providing separate crystal orientation layers for NMOS and PMOS.
  • SOQ (silicon on quartz)
    Transferred single-crystal silicon onto a quartz substrate used for RF, display, and optical applications.
  • SOG (silicon on glass)
    Transferred single-crystal silicon onto bulk glass, enabling low-cost, high-efficiency solar cells, displays, and optical applications.
  • CSS (customer specific substrate)
    A combination of donor-layer materials on unique handle substrates, including III-V and II-VI donor materials and sapphire, ceramics, and flexible handle substrates.

Layer Transfer Technology Processes The company's proprietary NanoCleave® (Layer Transfer), NanoBond (Plasma-activated bonding), and NanoSmooth (EpiSmoothing/Epi Thickening) process steps have allowed SiGen to become a leading provider of innovative-engineered substrates through its process and technology: enabling its customers to develop new applications with greater functionality and higher speed, while improving cost, power efficiency, and heat dissipation.
