Semiconductor reliability test chip
First Claim
1. A semiconductor test chip having a scribe area around the periphery thereof for simulating various conditions as a result of the manufacture, packaging, and use of a semiconductor chip, said test chip comprising:
- a chip including a periphery formed by at least four sides and a plurality of contact pads located substantially adjacent a portion of the periphery of the chip, a portion of the plurality of contact pads being located in a first row and a second row located substantially behind the first row on a portion of at least one side of the chip; and
a plurality of thin gate and thick gate transistor devices for the measurement of the temperature of the chip.

Abstract
A semiconductor test chip including a plurality of test functions. The test functions of the semiconductor test chip include bond pad pitch and size effects on chip design, wire bond placement accuracy regarding placement of the wire bond on the bond pad, evaluation of bond pad damage (cratering) effect on the area of the chip below the bond pad during bonding of the wire on the bond pad, street width effects regarding the use of thinner saw cuts in cutting the individual chips from the wafer, thermal impedance effects for thermal testing capabilities, ion mobility evaluation capabilities and chip on board in flip chip application test capabilities.
