Appeal No. 1998-3000
Application No. 08/485,412
polyimide/polymer material to electromagnetic radiation.
Claims 6, 24 and 51 are illustrative of the claimed
invention, and they read as follows:
6. An integrated circuit comprising at least a pair of
extended conductive elements lying in distinct
substantially parallel planes, and a radiation sensitive
polymer material interposed between said pair of said
conductive elements, said radiation sensitive polymer
material dosed with electromagnetic radiation to have
different conductivities in different portions forming a
continuous body with a substantially smooth surface from
portion to portion, with said pair of conductive elements
electrically linked by a said portion wherein the
radiation sensitive polymer material comprises a
polybenzimidazole (PBI) material.
24. A transistor comprising:
a radiation sensitive polymer material dosed with
electromagnetic radiation to have conductive regions
separated by another region of a lower conductivity
in the radiation sensitive material, and
a conductive material deposited over the region of
lower conductivity;
wherein the radiation sensitive material comprises a
polyimide.
51. A printed wiring board comprising a base including
selectively irradiated radiation sensitive polyimide
material, the board further having a conductor layer
affixed to said base and patterned into a set of conductors
wherein said radiation sensitive material is dosed with
electromagnetic radiation to have different
conductivities in different portions thereof, at least two
of the conductors electrically connected by a portion
of the dosed radiation sensitive material.
