Abstract:
Apparatus for electrical testing of electrical circuits includes an array of probes arranged for selective engagement with portions of electrical circuits to be tested, testing circuitry associated with the array of probes for sensing electrical characteristics of the electrical circuits engaged by the array of probes, and control circuitry associated with the array of probes for causing engagement between selected ones of the array of probes with selected ones of the portions of electrical circuits to be tested. The array of probes includes at least two static probe assemblies arranged in a fixed array, and the static probe assemblies include a selectively positionable probe element and a probe element positioner. The apparatus is employed to test electrical circuits during fabrication.
Abstract:
An optical inspection system has a topology sensing assembly. A height detector detects whether a region of a circuit has a height different from a height of the surface, and provides height data. A topology representation of the circuit, based on the height data, forms the basis for a reduced representation of the topology, and subsequent defect analysis.
Abstract:
A first inspection functionality is provided to obtain information about a first attribute at a conductor location on an electrical circuit. A second inspection functionality is provided to obtain information about a second attribute at the conductor location. A combination of first attribute information and second attribute information is analyzed to determine an inspection attribute of the conductor at the conductor location. Attribute information may relate to one or more of: reflectance, fluorescence or height.
Abstract:
A system and method for forming bumps on an integrated circuit including a scanning direct laser imager employed to selectably expose a photosensitive layer deposited on an integrated circuit substrate, thereby to define regions overlying selected portions of the substrate, a developer developing said photosensitive layer to form apertures in the photosensitive layer at the defined regions, and a solder applicator applying a solder composition to the apertures to define solder bumps on the integrated circuit at selected portions thereof.
