Group IV Epi wafers


Advanced Epi can also supply a range of group IV based semiconductors and alloys including:

  • Silicon
  • Germanium
  • Si1-xGex, Si1-xBx, Ge1-xSnx alloys


Epilayers can be grown on substrate sizes including 100, 150 and in certain cases 200 mm and doping profiles can be varied across many of the structures.

3C-SiC Epi wafers

Advanced Epi offers cubic silicon carbide (3C-SiC) epilayer grown on several different silicon substrates for various applications. Unless otherwise requested, epi wafers are packaged under cleanroom conditions without any additional characterisation techniques.


If requested, Advanced Epi offers a number of non-destructive and destructive characterisation processes including: FTIR thickness mapping, wafer bow measurements, AFM surface roughness mapping, 4-point probe resistance mapping, HR-XRD, SEM and TEM.


Substrates can be requested with the following parameters or in certain cases non-standard substrates can be supplied from customers:








3C-SiC epilayers can be grown at various thickness, typically between 50 - 1000 nm and be unintentionally doped or n-type doped. Advanced Epi's standard epi wafers are are 300 nm undoped 3C-SiC.


Typical 150mm 3C-SiC/Si Specifications

The following table shows the limits and typical parameters for 3C-SiC/Si epi wafer specifications grown on standard 675 micron thick 150 mm diameter Si substrates.

3C-SiC Membranes


Advanced Epi can supply customers with prototype 3C-SiC membranes for evaluation purposes. Membranes can be fabricated from 3C-SiC epilayers as thin as 25nm and above. Membranes sizes can range from hundreds of microns up to several millimetres.


​We are working closely semiconductor membranes manufacturers in order to offer these products on a fully commercial basis.
