Abstract: A system and method of metrology (10) whereby a three dimensional shape profile is defined (16) for a surface feature on a substrate by applying (38) a transform function F(x) to an image intensity map I(x,y) obtained (40) by inspecting the substrate with a scanning electron microscope (12). The transform function F(x) is developed (34) by correlating the image intensity map of a first wafer (18) to a height vector (32) obtained by inspecting the first wafer with a more accurate metrology tool, for example a stylus nanoprofilometer (14). A simple ratio-based transform may be used to develop F(x). An asymmetric multiple parameter characterization of the three dimensional shape profile may be developed (74) by plotting critical space and width dimensions (SL, SR, W1, WR) from a vertical axis (C—C) as a function of height of the feature.

Abstract: A manufacturing method using a modular substrate-based processing scheme for producing semiconductor devices, provides multiple modular processing units which may be arranged together to form any of various cohesive processing units or individually or sequentially processed through standard semiconductor processing equipment. The cohesive processing units are processed unitarily providing for multiple modular processing units to be processed simultaneously. The modular processing units may be formed of a thick semiconductor substrate or a semiconductor substrate mounted on a further substrate such as a ceramic material. The modular processing units may each contain ribs, grooves, posts or other features to aid in handling and placement of the individual units.

Abstract: A method and apparatus for minimizing the surface contamination of semiconductor wafers (11) during the semiconductor device manufacturing process. Semiconductor wafers (11) are stored in a storage cassette (12) with their face sides (17) facing downward and their back sides (16) facing upward. Particulate contamination present on the back sides of the wafers is thereby secured to the wafers by the force of gravity, and the faces of the wafers are shielded from falling debris. An automated wafer handling device (19) is provided with a rotary joint (22) to accomplish the wafer flipping motion before inserting a wafer into a cassette and after removing the wafer from the cassette.

Abstract: In-line process control for 120 nm and 100 nm lithography using the installed scanning electron microscope (SEM) equipment base. A virtual three-dimensional representation of a photoresist feature is developed by applying a transform function to SEM intensity data representing the feature. The transform function correlates highly accurate height vector data, such as provided by a stylus nanoprofilometer or scatterometer, with the highly precise intensity data from the SEM. A multiple parameter characterization of at least one critical dimension of the virtual feature is compared to an acceptance pattern template, with the results being used to control a downstream etch process or an upstream lithography process. A multiple parameter characteristic of a three dimensional representation of the resulting post-etch final feature may be compared to device performance data to further refine the acceptance pattern template.

Abstract: 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.

Abstract: A scanning probe microscope includes a sensor head adjacent a stage for holding a sample, a scanning actuator for positioning the sensor head relative to the sample, and a probe carried by the sensor head. The probe preferably includes a base connected to the sensor head, a shank extending from the base at an angle offset from perpendicular to the base, and a tip connected to a distal end of the shank for contacting the sample. The angle is preferably in a range of 5 to 20°. The tip is preferably laterally offset from the base to permit viewing of the tip without interference from the shank and the base. Thus, the location of the probe tip relative to the sample may be more easily determined.
