    摘要: A semiconductor integrated circuit device includes: a rectangular shaped semiconductor substrate; a metal wiring layer formed on or over the semiconductor substrate; and a passivation layer covering the metal wiring layer. A corner non-wiring region where no portion of the metal wiring layer is formed is disposed in a corner of the semiconductor substrate. A slit is formed in a portion of the metal wiring layer which is close to the corner of the semiconductor substrate. The passivation layer includes a first passivation layer which is formed on the metal wiring layer and a second passivation layer which is formed on the first passivation layer. The first passivation layer is formed of a material that is softer than a material of the second passivation layer.

    摘要: There is provided a nut having a thread portion having a female thread, a metallic plate portion having a base segment, and a hardness gradient portion provided between the thread portion and the metallic plate portion. The thread portion, metallic plate portion and the hardness gradient portion are monolithic each other, a metallographic structure of the metallic plate portion differs from a metallographic structure of the thread portion and a hardness of the hardness gradient portion is lower than a hardness of the thread portion and lowers from the thread portion toward the metallic plate portion.
