Inventor: NEPPL FRANZ DR
IPC: H01L21/8234
Filed: 1985-04-15
Granted: 1988-05-05
Abstract: A method for manufacture of gate electrodes formed of double layers of metal silicides having a high melting point and doped polycrystalline silicon. The polycystalline silicon is deposited in undoped fashion before the metal silicide and the doping of the silicon is obtained through the production of the source/drain-zones through ion implantation and a subsequent high temperature step. The method permits the problem-free manufacture of polycide-gates with n+- and p+-polysilicon on a chip without increased technological expense. Planarization is facilitated through the thin gate layers. The method is used in the manufacture of highly integrated CMOS-circuits.

Abstract: @ A continuous, multi-phase process for debossing and perforating a substantially continuous web of substantially planar polymeric film to coincide with the image of one or more forming structures, each having a patterned forming surface with a multiplicity of holes and an opposed surface. Each forming structure is open from the holes in the forming surface to its opposed surface. The web of film has an indefinite length, a first surface, a second surface and a thickness. The thickness comprises the distance between the first surface and the second surface. The process comprises at least two sequential.forming phases, one of which involves three-dimensional conformance of the web to the macroscopic profile of the forming structure and another of which involves aperturing of the web to coincide with fine-scale apertures in either the same or a separate forming structure. The order in which the phases are carried out will depend upon the properties desired in the resultant macroscopically expanded, three-dimensional, apertured polymeric web. Because the process is carried out in sequential phases, previously incompatible characteristics which could not be provided by prior art single-phase forming processes can now be achieved.
