GaP-on-Si-template technology

For the subsequent integration of III/V-material systems on CMOS-compatible Si (001) substrates these GaP-on-Si-templates serve as a perfect basis.

The GaP-on-Si-templates are widely used for production and development in the industry, research centers and universities for all kinds of applications, especially for the integration of optoelectronic III/V compound semiconductor material systems on silicon:

  • LEDs
  • Lasers
  • Optocoupling devices
  • Electronic systems and devices
  • Solar cells

With a lattice constant close to silicon, GaP is the material of choice as a basis for further epitaxial growth of III/V compound materials on silicon. Starting from this we have developed a high quality GaP layer with a defect free surface and an excellent smooth surface morphology. The GaP-on-Si-templates are free of misfit dislocations, threading dislocations, stacking faults, twins and are not disturbed by any anti-phase domains. The epitaxial layers have a high thickness uniformity and a high crystalline perfection.

We have optimized this technology on industrial CMOS standard 300mm substrates. A clean and particle free wafer exchange is guaranteed by the usage of the FOUP-cassette system.
