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.

A probe comprising a probe body having a body longitudinal axis and a shoulder, and a microstylet mechanically coupled to the shoulder, and a method of manufacturing the same. The microstylet extends from the shoulder and has a microstylet longitudinal axis coincident the body longitudinal axis with the microstylet having a cross section substantially smaller than a cross section of the probe body.

A probe tip locator for, and method of, use in determining a location of a probe tip relative to the probe tip locator comprising sets of discrete location markers in which numbers and positions of the location markers in each of the sets are employable uniquely to identify corresponding specific locations on the probe tip locator, the sets being distributed about the probe tip locator to avoid unbalanced partial encroachments into both sides of a scanpath of the probe tip by location markers in sets normally adjacent the scanpath thereby to prevent an erroneous determination of location caused by unbalanced partial encroachments of the location markers into both sides of the scanpath as the probe tip traverses the scanpath.

The present invention provides an apparatus and a method of manufacturing that apparatus. More specifically, to a method of manufacturing probes for a stylus nanoprofilometer having a non-circular probe tip geometry and a method of measurement of semiconductor wafer features using the same. In one embodiment, the probe comprises an upper portion couplable to the stylus nanoprofilometer and a probative portion coupled to the upper portion. The probative portion has a cross section that is substantially thinner than a cross section of the upper portion. The probative portion further has a terminus distal the upper portion and a reentrant angle from the terminus to the upper portion.

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 they may be 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.

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.

A reflective lens with at least one curved surface formed of polycrystalline material. In one embodiment, a lens structure includes a substrate having a surface of predetermined curvature and a film formed along a surface of the substrate with multiple individual members each having at least one similar orientation relative to the portion of the substrate surface adjacent the member such that collectively the members provide predictable angles for diffraction of x-rays generated from a common source. A system is also provided for performing an operation with x-rays. In one embodiment, a system includes a source for generating the x-rays, a polycrystalline surface region having crystal spacing suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, and transmitting the reflected x-rays to a reference position. An associated method includes providing x-rays to polycrystalline surface region having crystal spacings suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, transmitting the reflected x-rays to a reference position and positioning a sample between the surface region and the reference position so that the x-rays are transmitted through the sample.

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.

Illustratively, the present invention includes a method of integrated circuit manufacturing which includes forming a raised topological feature upon a first substrate. A portion of the raised feature is removed, thereby exposing a cross sectional view of the raised feature with the substrate remaining substantially undamaged. The cross sectional view has a critical dimension. The critical dimension of the cross sectional view is measured using a first measuring instrument. Then the critical dimension is measured using a second measuring instrument. The measurements of the first and second measuring instruments are correlated. Then, using the second measuring instrument, raised features via plurality of second substrates are measured.
