    摘要: A test selector that multiplexes different test structures (202) to an adjacent probe pad (206) in dependence on the probe voltage. In addition, a scribeline test circuit is disclosed that includes a test selector circuit located in a single scribeline portion between two adjacent die locations. Multiple test structures and at least one probe pad also are located in the single scribeline portion. The test selector circuit makes an electrical connection from the probe pad to a selected one of the test structures depending upon a voltage applied at the probe pad.

    摘要: An apparatus is provided for thermoforming a plurality of protrusions in a plastic sheet. The thermoforming apparatus comprises a pneumatic press having a pair of male and female die plates with respective projections and cavities. One of the die plates is heated. The other die plate is cooled. The cooled die plate is provided with vacuum to ensure that the thermoformed plastic sheet is held against the cooled die plate upon the opening of the press to, in turn, ensure the cooling of the plastic sheet prior to its removal.
