摘要： A system (70) for crystallography including a sample holder (74), an electron source (76) for generating an electron beam, and a scanning actuator (80) for controlling the relative movement between the electron beam and the crystalline sample, the scanning actuator being controllable for directing the electron beam at a series of spaced apart points within the sample area. The system also includes an image processor (84) for generating crystallographic data based upon electron diffraction from the crystalline sample and for determining whether sufficient data have been acquired to characterize the sample area. The system further includes a controller (86) for controlling the scanning actuator to space the points apart such that acquired data is representative of a different grains within the crystalline sample. IN other embodiments, the invention includes one or more ion beams (178, 188) for crystallography and a combination ion beam/electron beam (218, 228).

摘要： The present invention provides a method of determining a crystallographic quality of a material located on a substrate. The method includes determining a set of crystallographic solutions for an unknown crystallographic orientation, and subsequently comparing the set of crystallographic solutions to adjacent known crystallographic orientations to determine the unknown crystallographic orientation. In a preferred embodiment, the set of crystallographic solutions may be a rank of crystallographic solutions which may represent the most probable crystallographic orientations. The rank of crystallographic solutions, in an alternative embodiment, may be represented by a vote, a fit and a confidence index.

摘要： The present invention provides a method of forming a dynamic template with a focused beam. The method includes forming a desired template that represents a desired image, forming an actual template that represents an actual image, such as a photolithographic mask or a semiconductor device feature, and comparing the desired template to the actual template to yield a deviation template. In one embodiment the deviation template is formed by subtracting the actual template from the desired template.
