Abstract: Vertically insulated active semiconductor regions having different thicknesses in an SOI wafer, which has an insulating layer, is produced. On the wafer, first active semiconductor regions having a first thickness are arranged in a layer of active semiconductor material. The second active semiconductor regions having a relatively smaller thickness are produced by epitaxial growth proceeding from at least one seed opening in a trench structure. The second semiconductor regions are substantially completely dielectrically insulated, laterally and vertically, from the first semiconductor regions by oxide layers. The width of the seed opening can be defined by lithography.

Abstract: A technique is disclosed for increasing the width of a transistor (300) while the transistor itself may be scaled down. The transistor width (382) is increased by forming recesses (352) within shallow trench isolation (STI) regions (328) adjacent to the transistor (300). The recesses (352) provide an area that wraps around the transistor and thereby increases the width (382) of the transistor (300). This wraparound area provides additional space for dopant atom deposition, which facilitates a reduction in random dopant fluctuation (RDF). In this manner, transistors formed in accordance with one or more aspects of the present invention, may yield improved performance when incorporated into SRAM since the probability that such transistors will be more closely matched is increased.

Abstract: A method for forming metrology structures for a CMP process is described. A trench edge is formed in a base material or stack of materials which are preferably deposited as part of the process of fabricating the production structures on the wafer. A covering film of a second material with preferably with contrasting SEM properties is deposited over the trench edge in the base material. During CMP the covering film is preferentially worn away at the edge revealing the base material. The width of the base material which has been revealed is a measure of the progress of the CMP. Since the base material and the covering material are preferably selected to have contrasting images in an SEM, a CD-SEM can be used to precisely measure the CMP progress.

Abstract: A dry-etching method using an apparatus where a wafer is placed on either of a pair of opposed electrodes provided in an etching chamber, and high-frequency power is supplied to both the opposed electrodes to effect a plasma etching.

Thus, the trenches can have desired shapes even if the widths of the trenches are different.
