Title: Method for electrolytically forming conductor structures from highly pure copper when producing integrated circuits
Inventor: THIES ANDREAS
IPC: H01L21/28
Filed: 2000-01-11
Abstract: The invention relates to a method for galvanically forming conductor structures of high-purity copper on surfaces of semiconductor substrates (wafers) (1) during the production of integrated circuits, said semiconductor substrates being provided with indentations (2). The inventive method comprises the following steps: a) coating the entire surfaces of the semiconductor substrates (1) which are provided with indentations (2) with a backing material layer in order to obtain a sufficient conductivity for the galvanic deposition process; b) depositing copper layers (3) having an even layer thickness on the entire surface of the backing material layer via a galvanic metal deposition process by contacting the semiconductor substrates with a copper deposition bath. Said copper deposition bath contains at least one copper ion source, at least one additive compound for controlling the physico-mechanical properties of the copper layers and Fe(II) and/or Fe(II) compounds. Between the semiconductor substrates and the dimension-stable counter-electrodes which are contacted with said bath and which are insoluble therein an electric potential is applied so that an electric current flows between the semiconductor substrates (1) and the counter-electrodes. In a last step of the inventive method, c) the copper layer (3) is structured.

Title: Quantization in perceptual audio coders with compensation for synthesis filter noise spreading
Inventor: DAVIDSON GRANT ALLEN
IPC: G10L19/02
Filed: 2000-04-10
Abstract: Many perceptual split-band coding systems that use analysis and synthesis filters assume the quantization noise introduced by quantizing split-band signals is substantially the same as the noise that results in the output signal obtained by applying the synthesis filters to the quantized split-band signals. In general, this assumption is not true because the synthesis filters modify or spread the quantization noise. A theoretical framework for deriving an optimum bit allocation that accounts for synthesis-filter noise spreading is disclosed. In concept, the problem of finding an optimal bit allocation can be expressed as a linear optimization problem in a multidimensional coordinate space. Simplified processes derived from this theoretical framework are disclosed that can obtain near-optimal solutions using modest computational resources.
