  • Structure and process for testing integrated circuits permitting determination of the properties of layers
    Patent number: 4906921
    Abstract: The instant invention relates to a test structure for an integrated circuit for determining the incidence of various conduction effects on given layers and separating the surface effects from the wedge effects and the periphery effects into two perpendicular directions, wherein test patterns of determined shapes are incorporated into elementary components comprising the given layers transversely polarized, further comprising at least four test patterns (11, 13, 15, 17) in which the given layers are delimited according to four rectangles, each of which has a common dimension with another one, that is, those four rectangles have only two length values (YD) and two width values (XD).
