  • Patent number: 8779593
    Abstract: Also in a semiconductor integrated circuit device including a copper embedded wiring as a main wiring layer, generally, the uppermost-layer wiring layer is often an aluminum-based pad layer in order to ensure wire bonding characteristics. The aluminum-based pad layer is also generally used as a wiring layer (general intercoupling wiring such as power source wiring or signal wiring). However, such a general intercoupling wiring has a relatively large wiring length. This causes a demerit for the device to be susceptible to damages during a plasma treatment due to the antenna effect, and other demerits. With the present invention, in a semiconductor integrated circuit device including a metal multilayer wiring system having a lower-layer embedded type multilayer wiring layer and an upper-layer non-embedded type aluminum-based pad metal layer, the non-embedded type aluminum-based pad metal layer substantially does not have a power supply ring wiring.

  • Patent number: 8242613
    Abstract: A semiconductor die has rows of bond pads along the edges of a major surface. The corners of the die are designated as keep out areas, with design layout rules prohibiting a probe-able bond pad from being placed in the keep out areas so that a minimum distance may be maintained between distal ends of adjacent rows of bond pads (i.e., bond pads along adjacent edges). The bond pads of each row have IO pad areas that are aligned with each other and IO probe areas that are aligned with each other. A generally L-shaped bond pad includes a first, vertical part that extends inwardly from an edge of the semiconductor die and a second, horizontal part connected to the vertical part. The L-shaped bond pad may be placed between a last bond pad in a row and a corner keep out area, and the second part of the L-shaped bond pad extends into the corner keep out area.

  • Patent number: 8183645
    Abstract: Flexibility for the design of the pattern layout of the gate lead-out electrode and the source electrode is enhanced without increasing the chip thickness of the semiconductor device. A semiconductor device includes a cell region where plural transistor cells are arranged and a gate finger region different from a region where the cell region is formed. In the cell region, a gate electrode formed of a polysilicon (first conductive material) is formed. A polysilicon layer formed indivisibly with the gate electrode is formed in the gate finger region. An adhesion metal layer and a wiring metal layer are formed above the polysilicon layer by a lift-off method. The gate lead-out electrode is formed of a laminate structure including the polysilicon layer, the adhesion metal layer, and the wiring metal layer. A single layer of interlayer insulation film covering them is formed, on which a source electrode is formed.
