Title: Process for the preparation of polyimidazole and polyimidazopyrrolone relief structures
Inventor: AHNE HELLMUT DR
IPC: H01L21/027
Filed: 1984-12-12
Granted: 1988-04-14
Abstract: Highly heat-resistant polyimidazole and polyimidazopyrrolone relief structures can be manufactured in a very pure form and with short exposure times by applying radiation-sensitive soluble polymer precursors in the form of a layer or a foil to a substrate, irradiating the layer or foil through negative patterns with actinic light, or electrons, or by guiding a light, electron, ion, or laser beam, removing the non-irradiated layer or foil parts, and optionally subsequently annealing. Thereby reaction products, which are prepared in the presence of carbodiimides, of aromatic and/or heterocyclic tetraamino compounds and either: (a) olefinically unsaturated monocarboxylic acids and dicarboxylic acids, or (b) olefinically unsaturated monocarboxylic acids and aromatic and/or heterocyclic tetracarboxylic acid dianhydrides, or (c) olefinically unsaturated tetracarboxylic acid diesters in the form of addition products of the tetracarboxylic acid dianhydrides and olefinically unsaturated alcohols are used as polymer precursors. The relief structures prepared according to the invention are particularly well suited for use as a resist, surface protection, and because of their high purity, as a durable protective and insulating material in the semiconductor area.

Abstract: The planar bipolar transistor is formed as a part of an integrated circuit in the surface of a semiconductor substrate. It forms a collector region within a window formed in the field-oxide and a base- as well as an emitter-region. The emitter zone is covered with a masking layer which masks against a low energy base-impurity implant but does not mask against a high energy base-impurity implant after the collector-region has been diffused. While the rest of the collector diffusion-surface has been masked with a photoresist layer the base-implants are made. During thermaloxidation following these implants thick oxide regions are formed over the base area not protected by the masking layer. This masking layer is then removed for deposition of a polycrystalline Si-layer, pref. doped with the emitter-impurity, a silicide-layer and an insulation layer. The oxide-areas are then etched anisotropically revealing the base-collector junction, to form base-contacts. An implant of the base-impurity is made into these windows using the composite layer as a mask. An insulation layer is then deposited and etched anisotropically to form insulation for the edges of the emitter and collector electrodes. Then the base-implant is activated and a metallisation layer deposited which is defined with a photoresist process. Also claimed is the above process with the addition of an implant of the emitter-impurity in the emitter area before deposition of the specified layers.
