  • Patent number: 8182709
    Abstract: By creating a temperature profile across a polishing pad, a respective temperature profile may be obtained in a substrate to be polished, which may result in a respective varying removal rate across the substrate for a chemically reactive slurry material or for an electro-chemically activated polishing process. Hence, highly sensitive materials, such as material comprising low-k dielectrics, may be efficiently polished with a high degree of controllability.

  • Patent number: 8183139
    Abstract: Superior contact elements may be formed in semiconductor devices in which sophisticated replacement gate approaches may be applied. To this end, a dielectric cap layer is provided prior to patterning the interlayer dielectric material so that any previously created cracks may be reliably sealed prior to the deposition of the contact material, while the removal of any excess portion thereof may be performed without an undue interaction with the electrode metal of the gate electrode structures. Consequently, a significantly reduced defect rate may be achieved.

  • Patent number: 8183096
    Abstract: A static RAM cell may be formed on the basis of two double channel transistors and a select transistor, wherein a body contact may be positioned laterally between the two double channel transistors in the form of a dummy gate electrode structure, while a further rectangular contact may connect the gate electrodes, the source regions and the body contact, thereby establishing a conductive path to the body regions of the transistors. Hence, compared to conventional body contacts, a very space-efficient configuration may be established so that bit density in static RAM cells may be significantly increased.

  • Patent number: 8183605
    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.

  • Patent number: 8183100
    Abstract: In sophisticated semiconductor devices, a strain-inducing semiconductor alloy may be positioned close to the channel region by forming cavities on the basis of a wet chemical etch process, which may have an anisotropic etch behavior with respect to different crystallographic orientations. In one embodiment, TMAH may be used which exhibits, in addition to the anisotropic etch behavior, a high etch selectivity with respect to silicon dioxide, thereby enabling extremely thin etch stop layers which additionally provide the possibility of further reducing the offset from the channel region while not unduly contributing to overall process variability.

  • Patent number: 8180471
    Abstract: A method for estimating a state of a process implemented by a tool for fabricating workpieces includes collecting metrology data associated with a subset of workpieces processed in the tool. The collecting exhibits an irregular pattern. Metrology data associated with a selected state observation is received for a selected run of the process. A tuning factor for the selected run is determined based on the irregular pattern. The selected state observation is discounted based on the determined tuning factor. A state estimate of the process is determined based on the discounted selected state observation. At least one process tool operable to implement the process is controlled based on the state estimate.
