Inventor: BRODT GREGOR
IPC: C25D3/22
Filed: 2001-07-09
Abstract: The invention relates to a method for electrolytically coating metalswith zinc or a zinc alloy. Matt surfaces are obtained by depositing zinc from an electrolyte solution containing a zinc salt selected from zinc sulphate or an alkane sulphate of zinc or mixtures thereof and optionally other metal salts, an acid selected from sulphuric acid or an alkane sulphonic acid or a mixture of both acids and at least one additive for improving surface roughness and for avoiding dendritic edge growth, selected from surface active compounds containing nitrogen which can be ionic or non-ionic, anionic surface active compounds containing nitrogen, and surface active compounds derived from multi-fuctional alcohols with at least three hydroxy groups. The invention also relates to an electrolytic composition for an electrolytically coating of metals with zinc or zinc alloys, in addition to the use of the above-mentioned additives for improving surface roughness and avoiding dentritic edge growth when metals are electrolytically coated with zinc or a zinc alloy in an electrolyte containing alkane sulphonic acid.

Title: Metal-insulator-metal capacitor in copper
Inventor: ARMACOST MICHAEL D
IPC: H01L21/3213
Filed: 2002-01-16
Abstract: A parallel plate capacitor in copper technology is formed in an area that has no copper below it (within 0.3ν) with a bottom etch stop layer (104), a composite bottom plate (110) having an aluminium layer below a TiN layer, an oxide capacitor dielectric (120), and a top plate (130) of TiN. The process involves etching the top plate to leave a capacitor area, etching the bottom plate to a larger bottom area having a margin on all sides; depositing an interlayer dielectric having a higher material quality below the top surface of the capacitor top plate; opening contact apertures to the top and bottom plates and to lower interconnect to a two step process that partially opens a nitride cap layer on the lower interconnect and the top plate while penetrating the nitride cap layer above the bottom plate, then cutting through the capacitor dielectric and finishing the penetration of the nitride cap layer.

Title: Energy storage, distribution and production system - stores water from power stations in underground lakes
Inventor: DENIS LOUIS HENRI DANIEL
IPC: F01K3/00
Filed: 1974-10-08
Abstract: Power generators may work at a constant rate, i.e. coal, oil fired or nuclear power stations, hence improving the overall efficiency, by the storage, during low energy demand periods, of heated water in large underground natural lakes. This smoothing of generation requirements is envisaged as covering the demand over the whole year, i.e. storage during the summer months against the high winter demand. The energy stored in this manner is utilised when required by heat pumps, water temperature being raised from about 80 deg. C to 120 deg. C - 140 deg. C. The stirling cycle may be used to provide mechanical conversion. Further storage is by dam and barrage.
