摘要:
A stiffener attached to the magnetic head or heads in a tape drive to support the flexible circuit and provide a flat surface against which the flexible circuit rolls when the head moves up and down. The stiffener is, preferably, fastened to a head carrier that is attached directly to the magnetic head. This head sub-assembly is mounted to the movable carriage that carries the head up and down at the urging of the head positioning actuator.
摘要:
An integrated circuit probing method and apparatus therefor. The apparatus includes a main system controller coupled to a network interface, graphic user interface, and equipment interface. A high speed bus connects the main system controller to a group of subsystems. The subsystems includes subsystems such as input cassettes, input frame handing, frame to align, die align, die probing, die bin and die output, output cassettes subsystem, among others. The integrated circuit probing apparatus allows for probing of each individual die through the die probing subsystem, typically a high speed subsystem.

摘要:
A process for contouring a via formed in a dielectrics whereby a layer of a refractory metal is formed on the dielectric and in the via. The refractory metal layer is removed until a surface of the refractory metal within the via is below the upper surface of the dielectric. An etching process removes a portion of the dielectric and a tapered shape is formed at the intersection of the via and the upper surface of the dielectric. A second layer of metal is formed over the dielectric, with the second layer of metal extending into the vias and contacting the refractory metal with the tapered shape providing improved step coverage of the second layer of metal at the via.
摘要:
A semiconductor wafer probe test interface system (2) and method of operating the system. The wafer probe system includes a plurality of cassettes (302) adapted to hold wafer probe test cards (304). The cassettes are loaded into position for testing of semiconductor wafers with a transport assembly system (6). A memory device (316) on the cassette is used to store data regarding usage of the card such as number of wafer touchdowns. A smart controller (220) has the capability to "talk" to the prober and tester.
