摘要： A method for assessing metrology tool accuracy is described. Multi-variable regression is used to define the accuracy of a metrology tool such that the interaction between different measurement parameters is taken into account. A metrology tool under test (MTUT) and a reference metrology tool (RMT) are used to measure a set of test profiles. The MTUT measures the test profiles to generate a MTUT data set for a first measurement parameter. The RMT measures the test profiles to generate RMT data sets for the first measurement parameter, and at least a second measurement parameter. Multi-variable regression is then performed to generate a best-fit plane for the data sets. The coefficient of determination (R2 value) represents the accuracy index of the MTUT.

摘要： The present invention provides a method of annealing a semiconductor by applying a temperature-dependant phase switch layer to a semiconductor structure. The temperature-dependant phase switch layer changes phase from amorphous to crystalline at a predetermined temperature. When the semiconductor structure is annealed, electromagnetic radiation passes through the temperature-dependant phase switch layer before reaching the semiconductor structure. When a desired annealing temperature is reached the temperature-dependant phase switch layer substantially blocks the electromagnetic radiation from reaching the semiconductor structure. As a result, the semiconductor is annealed at a consistent temperature across the wafer. The temperature at which the temperature-dependant phase switch layer changes phase can be controlled by an ion implantation process.

摘要： A transistor having an epitaxial channel and a method for fabricating a semiconductor device having an epitaxial channel, the method including forming a hardmask on a substrate and forming an opening in the hardmask. The opening is geometrically characterized by a long dimension and a short dimension, and the opening is arranged in a predetermined manner relative to the channel region of a transistor. An epitaxial material is formed in the opening that induces strain in substrate regions proximate to the epitaxial material. The epitaxial material is confined to the opening, such that an epitaxial channel is formed. A transistor is fabricated in proximity to the epitaxial channel, such that the strain induced in the substrate provides enhanced transistor performance. By confining the epitaxial material to a predefined channel in the substrate, plastic strain relaxation of the epitaxial material is minimized and a maximum amount of strain is induced in the substrate.
