Abstract: Separating a carbon doped silicon containing dielectric layer by low temperature gas phase separation of a surface comprises reacting a silicon organic compound with hydrogen peroxide to separate a dielectric layer on the surface, where the silicon organic compound exhibits at least one Si-O-Si bond. An independent claim is also included for a premetal dielectric (PMD)-semiconductor structure comprising: (a) semiconductor layer, which exhibits a distance between one another on a surface of a layer; and (b) dielectric layer, which exhibits at least a space filled without a cavity.

Abstract: Production of a shallow trench insulation structure comprises forming a mask (3) on a substrate (1), forming trenches (2) in the substrate using a mask, selectively depositing a first insulating material (5) to partially fill the trenches with the insulating material in the presence of the mask, and applying a second insulating material (6) on the whole surface of the structure to fill the trenches in the substrate up to the upper side of the mask.

Abstract: The method involves pretreating a semiconductor structure before superimposing the spin-on layer to obtain a plane surface of the spin-on layer. A liner layer is superimposed on a semiconductor structure before the superimposition of the spin-on-layer. The semiconductor structure supports a planar superimposition of the spin-on layer on it. An oxide layer is superimposed as a liner layer, whose thickness is greater than 2.0 mm. An independent claim is also included for a semiconductor structure, in particular a semiconductor wafer with a substrate.

Abstract: The present invention provides a fabrication method for a semiconductor structure having the steps of providing a semiconductor substrate ( 1 ); providing and patterning a silicon nitride layer ( 3 ) on the semiconductor substrate ( 1 ) as topmost layer of a trench etching mask; forming a trench ( 5 ) in a first etching step by means of the trench etching mask; conformally depositing a liner layer ( 10 ) made of silicon oxide above the resulting structure, which leaves a gap (SP) reaching into the depth in the trench ( 5 ); carrying out a V plasma etching step for forming a V profile of the line layer ( 10 ) in the trench ( 5 ); wherein the liner layer ( 10 ) is pulled back to below the top side of the silicon nitride layer ( 3 ); an etching gas mixture comprises C 5 F 8 , O 2 and an inert gas is used in the V plasma etching step; the ratio (V) of C 5 F 8 /O 2 lies between 2.5 and 3.5; and the selectivity of the V plasma etching step between silicon oxide and silicon nitride is at least 10.

Abstract: Filling contact holes (2) in a dielectric layer (3) on a substrate, with a metal compound, comprises removing impurities from the walls of the holes, gassing out residues at high temperature, and then applying an adhesive layer (4) onto the dielectric surface. The filling (1) is applied to the adhesive layer, so the hole is completely filled The adhesive layer comprises TiN or Ti/TiN.
