  substrate 
 
    The  body  or  base  layer  of  an  {integrated  circuit}, 
  onto  which  other  layers  are  deposited  to  form  the  circuit. 
  The  substrate  is  usually  Silicon,  though  Sapphire  is  used  for 
  certain  applications,  particularly  military,  where  radiation 
  resistance  is  important.  The  substrate  is  originally  part  of 
  the  {wafer}  from  which  the  {die}  is  cut.  It  is  used  as  the 
  electrical  {ground}  for  the  circuit.
