Abstract: A process for the production of highly integrated circuits contaiining p- and n-channel MOS transistors including gate electrodes which consist of a doped double layer of polysilicon and metal silicide. The gates are doped with boron and are produced by diffusion from the metal silicide layer which has previously been doped with boron by ion implantation into the undoped polysilicon layer. The metal silicide layer preferably consisting of tantalum silicide is provided with a masking layer consisting of SiO2, and the structuring of the boron-doped silicide gate and the masking layer is carried out after the boron atoms have been diffused in. The process serves to safely avoid undesired boron penetration effects which considerably influence the short channel properties of the transistors. The process is used for the production of CMOS-circuits having a high packing density.

Abstract: The invention relates to a process for separating heavy metals from waste water and to precipitant for carrying out this process and to process for manufacturing the precipitant. It known to use the alkaline hydroxide precipitation and the sulphide precipitation to separate heavy metals from waste water. However, these known processes are associated with serious disadvantages which, in the final analysis, have prevented their use in practice. The invention proposes, in a process according to the generic part, to combine the intrinsic advantages of sulphide precipitation in an acid medium, namely the extremely low residual solubilities of the heavy metals, with the considerable reduction in the risks of possible overdosage, i.e. safety from formation of hydrogen sulphide. The precipitant used is designed in such a way that the sulphide and other precipitates in the treated waste water automatically flocculate out at a pH of about 7.5, the sludge becoming separated from the clear water without addition of flocculating agents. The agent for separating heavy metals advantageously consists of alkaline earth metal polysulphides or mixtures of alkaline earth metal polysulphides with other alkaline earth metal sulphur compounds.
