Abstract: An evaluation configuration has a first MOS evaluation stage, an isolation stage, and a bipolar evaluation stage. The isolation stage is connected between the first MOS evaluation stage and the bipolar evaluation stage. The isolation stage isolates the first MOS evaluation stage from the bipolar evaluation stage. The evaluation configuration can reliably detect very small read signals and allows a high integration density.

Abstract: Novel poly-o-hydroxyamides can be cyclized to give polybenzoxazoles which have a good diffusion barrier effect with respect to metals. The poly-o-hydroxyamides can be applied to a semiconductor substrate by customary techniques and converted into the polybenzoxazole in a simple manner by heating. This results in a good barrier layer with respect to diffusion of metals. This allows the diffusion barrier between conductor track and dielectric to be substantially dispensed.

Abstract: A heating system, a method for heating a deposition reactor or an oxidation reactor, and a reactor utilizing the heating system are particularly suited for low-pressure chemical vapor deposition or oxidation. A heating system is particularly useful for heating a reactor in which a plurality of wafers is held perpendicularly to the reactant gas flowing direction that is parallel to the longitudinal axis of the reactor, to enable a deposition or oxidation reaction. The heating system is adapted to change the reactor temperature during the process. In addition, a method heats a reactor to enable a reaction. Preferably, each of a plurality of reactor zones, into which the reactor is divided in a direction parallel to the reactant gas flowing direction, is heated at a different temperature profile indicating the temperature of this specific zone versus time. Thereby, the in-plane uniformity of deposited or oxidized layers can be largely improved.
