Hi all,
  Where to get Commercial polyimide having the following properties.
  1) Spin coated and when ppr develops, the polyimide gets etched there by
transfering the pattern from the photoresist.
  2) Transparent to light in the wave length range of 1.3 to 1.55micrometer &
with low absorption characteristic.
  3)Curing temperature less than 300C.
  Please reply if any one has used the above said.
  Thank you,
  Sheela
