摘要： A method of fabricating a barrier layer includes oxidizing a silicon-containing substrate to form a substrate oxide layer on the surface of the substrate, producing an oxygen-impervious layer at an interface between the substrate oxide layer and the substrate, and etching the substrate oxide layer until the underlying oxygen-impervious layer is uncovered.

摘要： A trench capacitor is formed with an insulation collar. After the formation of the trench, firstly an insulating layer is deposited, from which layer the insulation collar will be subsequently formed. Afterward, the trench is partly filled with a sacrificial filling material and a thin patterning layer is deposited thereon. Spacers are formed from that layer and cover the insulating layer in the upper region of the trench. Afterward, the sacrificial filling material and the insulating layer are completely removed in the lower region of the trench. As a result, the insulation collar is produced in the upper region of the trench.

摘要： The instant invention is a method for fabricating a trench contact to a deep trench capacitor with a polysilicon filling in a trench hole formed in a silicon substrate. An epitaxy process is performed to selectively grow silicon above the polysilicon filling in the trench hole. An opening leading to the polysilicon filling is anisotropically etched into the epitaxially grown silicon. The opening has lateral dimensions that are smaller than those of the polysilicon filling, and the opening is filled with polysilicon.

摘要： A trench capacitor, in particular for use in a semiconductor memory cell, has a trench formed in a substrate; an insulation collar formed in an upper region of the trench; an optional buried plate in the substrate region serving as a first capacitor plate; a dielectric layer lining the lower region of the trench and the insulation collar as a capacitor dielectric; a conductive second filling material filled into the trench as a second capacitor plate; and a buried contact underneath the surface of the substrate. The substrate has, underneath its surface in the region of the buried contact, a doped region introduced by implantation, plasma doping and/or vapor phase deposition. A tunnel layer, in particular an oxide, nitride or oxinitride layer, is preferably formed at the interface of the buried contact. A method for producing a trench capacitor is also provided.

摘要： A method for reducing a capacitance formed on a silicon substrate includes the step of introducing hydrogen atoms into a portion of said surface to increase the dielectric constant of such portion of the surface increasing the effective thickness of the dielectric material and hence reducing said capacitance. The method includes the step of forming the silicon dioxide layer with a thickness greater than two nanometers. The step of introducing hydrogen includes forming hydrogen atoms in the surface with concentrations of 1017 atoms per cubic centimeter, or greater. In one embodiment the hydrogen atoms are introduced by baking in hydrogen at a temperature of 950° C. to 1100° C. and pressure greater than 100 Torr. A trench capacitor DRAM cell is provided wherein the hydrogen provides a passivation layer to increase the effective capacitance around a collar region and thereby reduce unwanted transistor action.
