Abstract: By providing a protection layer on a silicon/germanium material of high germanium concentration, a corresponding loss of strained semiconductor material may be significantly reduced or even completely avoided. The protection layer may be formed prior to critical cleaning processes and may be maintained until the formation of metal silicide regions. Hence, high performance gain of P-type transistors may be accomplished without requiring massive overfill during the selective epitaxial growth process.

Abstract: A component is produced according to the following steps: a) insertion at least of two skins into the second tool half of a tool having a cavity-forming first tool half and second tool half such that the skins overlap in their end regions; b) rear-foaming or rear-spraying of the skins with a foam material or spraying material, c) by exerting low pressure in the region of the overlap, the internally situated end region of the one skin being pressed against the externally situated end region of the other skin in a foam-tight or injection molding-tight manner.

Abstract: A substrate diode for an SOI device is formed in accordance with an appropriately designed manufacturing flow, wherein transistor performance enhancing mechanisms may be implemented substantially without affecting the diode characteristics. In one aspect, respective openings for the substrate diode may be formed after the formation of a corresponding sidewall spacer structure used for defining the drain and source regions, thereby obtaining a significant lateral distribution of the dopants in the diode areas, which may therefore provide sufficient process margins during a subsequent silicidation sequence on the basis of a removal of the spacers in the transistor devices. In a further aspect, in addition to or alternatively, an offset spacer may be formed substantially without affecting the configuration of respective transistor devices.

Abstract: By removing an outer spacer of a transistor element, used for the formation of highly complex lateral dopant profiles, prior to the formation of metal silicide, employing a wet chemical etch process, it is possible to position a stressed contact liner layer more closely to the channel region, thereby allowing a highly efficient stress transfer mechanism for creating a corresponding strain in the channel region, without affecting circuit elements in the P-type regions.

Abstract: By recessing portions of the drain and source areas on the basis of a spacer structure, the subsequent implantation process for forming the deep drain and source regions may result in a moderately high dopant concentration extending down to the buried insulating layer of an SOI transistor. Furthermore, the spacer structure maintains a significant amount of a strained semiconductor alloy with its original thickness, thereby providing an efficient strain-inducing mechanism. By using sophisticated anneal techniques, undue lateral diffusion may be avoided, thereby allowing a reduction of the lateral width of the respective spacers and thus a reduction of the length of the transistor devices. Hence, enhanced charge carrier mobility in combination with reduced junction capacitance may be accomplished on the basis of reduced lateral dimensions.

Abstract: After forming the outer drain and source regions of an N-channel transistor, the spacer structure may be removed on the basis of an appropriately designed etch stop layer so that a rigid material layer may be positioned more closely to the gate electrode, thereby enhancing the overall strain-inducing mechanism during a subsequent anneal process in the presence of the material layer and providing an enhanced stress memorization technique (SMT). In some illustrative embodiments, a selective SMT approach may be provided.

Abstract: By repeatedly applying a process sequence comprising an etch process and a selective epitaxial growth process during the formation of drain and source areas in a transistor device, highly complex dopant profiles may be generated on the basis of in situ doping.

Abstract: A new technique enables providing a stress-inducing alloy having a highly stress-inducing region and a region which is processable by standard processing steps suitable for use in a commercial high volume semiconductor device manufacturing environment. The regions may be formed by a growth process with a varying composition of the growing material or by other methods such as ion implantation. The highly stress-inducing region near the channel region of a transistor may be covered with an appropriate cover.

Abstract: By selectively applying a stress memorization technique to N-channel transistors, a significant improvement of transistor performance may be achieved. High selectivity in applying the stress memorization approach may be accomplished by substantially maintaining the crystalline state of the P-channel transistors while annealing the N-channel transistors in the presence of an appropriate material layer which may not to be patterned prior to the anneal process, thereby avoiding additional lithography and masking steps.

Abstract: A method of forming a semiconductor structure comprises providing a semiconductor substrate comprising a first transistor element and a second transistor element. The first transistor element comprises at least one first amorphous region and the second transistor element comprises at least one second amorphous region. A stress-creating layer is formed over the first transistor element. The stress-creating layer does not cover the second transistor element. A first annealing process is performed. The first annealing process is adapted to re-crystallize the first amorphous region and the second amorphous region. After the first annealing process, a second annealing process is performed. The stress-creating layer remains on the semiconductor substrate during the second annealing process.

Abstract: By appropriately adapting the length direction and width directions of transistor devices with respect to the crystallographic orientation of the semiconductor material such that identical vertical and horizontal growth planes upon re-crystallizing amorphized portions are obtained, the number of corresponding stacking faults may be significantly reduced. Hence, transistor elements with extremely shallow PN junctions may be formed on the basis of pre-amorphization implantation processes while substantially avoiding any undue side effects typically obtained in conventional techniques due to stacking faults.
