摘要:
The invention relates to a method for producing a strained layer. Said method comprises the following steps: placing the layer on a substrate and straining it, structuring the strained layer, relaxing the layer, producing directional off-sets in the layer to be strained. A layered structure produced in this manner has triaxially strained layers.

The invention relates to a method for producing a layer structure comprising a strained layer on a substrate. The inventive method comprises the steps of producing a defect area in a layer adjoining the layer to be strained, and relaxing at least one layer adjoining the layer to be strained. The defect area is especially produced in the substrate. Additional layers can be epitactically grown. Layer structures so produced are especially suitable for producing various types of components.

The invention relates to a method for the production of a monocrystalline layer on a substrate with a non-adapted lattice. To this end, a monocrystalline substrate with a buried amply defective layer and a monocrystalline layer produce thereon are used. The buried amply defective layer can be produced by hydrogen implantation.

The invention relates to a method for the production of a monocrystalline, stress-relaxed layer structure having one or several layers on a substrate with different grid structure. In a special embodiment, the method can be advantageously used for the production of relaxed silicon on a stress-related Si—Ge layer structure. The invention also refers to the utilization of said layer system in components such as MOSFETs, MODFETs, resonant tunnel diodes, photodetectors or quantum cascade lasers.

The invention relates to a method for producing a tensioned layer on a substrate involving the following steps: producing a defect area in a layer adjacent to the layer to be tensioned, and; relaxing at least one layer adjacent to the layer to be tensioned. Additional layers can be epitaxially deposited. Layer structures formed in this manner are advantageously suited for components of all types.

The invention relates to a method for the production of passivated defining surfaces (6a, 6b) between a first layer, such as a silicide (5), and an adjacent layer. Passivating elements, such as S, Se and Te are used in said layer structure during said method and the first layer is enriched on the adjacent layer during heat treatment on at least one defining surface. Schottky barriers can be reduced and output work of the transition can be adjusted. Components, e.g. Schottky barrier MOSFETs with small or negative Schottky barriers arc disclosed as source and/or drain contacts and spin transistors.
摘要:
A process for producing a layered structure in which a silicide layer on a silicon substrate is subjected to local oxidation to cause the boundary layer side of the silicide layer to grow into the silicon substrate.
摘要:
An epitaxial growth of a first component of a multilayer stack for use in optical, electro-optical and electronic or magnetic components, e.g. on a silicon wafer, can be formed by depositing a second component in a form in which that second component produces a precipitate or inclusions in the first component which with continued deposition may be partly replaced by a third component so that the precipitate itself is buried in a monocrystalline structure and, after a thermal treatment in which the precipitate coalesces, a buried layer is formed of the second component or a compound thereof with, say, the first component, in that monocrystalline structure.
摘要:
A silicon on insulator (SOI) substrate is converted into a strained SOI substrate by first providing an SOI substrate having a thin silicon layer and an insulator and at least one first epitaxial relaxing layer on the SOI-substrate. Then a defect region is produced in a layer by implantation of SI ions above the silicon layer of the SOI-substrate. Finally the first layer is relaxed by a thermal treatment in an inert atmosphere to simultaneously strain the silicon layer of the SOI-substrate via dislocation mediated strain transfer and to produce the strained silicon layer directly on the insulator.
