>> Since you need SOI with a thick layer (15 micron) of
>> silicon film, you may only have the option of Bonded-
>> and-Etchback SOI (BESOI) which permits such thicker
>> layers.  The alternative is (oxygen-implanted) SIMOX
>> wafers that subsequently require epi-silicon grown
>> on a thin 200-nm silicon film.
>>
>> For BESOI, you might try contacting either SiBond
>> L.L.C. (Hopewell Junction, NY) or Shin-Etsu Handotai -
>> SEH (Isobe, Japan or Washington State, USA).
