A semiconductor device including a multiplicity of large current power elements with each power element divided into a multiplicity of divisional elements and arranged such that the power elements belonging to different power elements are arranged in a repetitive sequential order. The IC chip of the semiconductor device is formed to have output wires extending from the respective divisional elements connected to corresponding output pads without crossing other output wires. Arranged on the IC chip are output bumps in association with the respective output pads. A rewiring layer is provided having output coupling wires for connecting together the bumps that belong to the same power element and connecting them further to an external output electrode.

Methods, systems, and devices for buried lines and related fabrication techniques are described. An electronic device (e.g., an integrated circuit) may include multiple buried lines at multiple layers of a stack. For example, a first layer of the stack may include multiple buried lines formed based on a pattern of vias formed at an upper layer of the stack. The pattern of vias may be formed in a wide variety of spatial configurations, and may allow for conductive material to be deposited at a buried target layer. In some cases, buried lines may be formed at multiple layers of the stack concurrently.

A first impurity region and a second impurity region, having first and second types of conductivity, respectively, are formed on a substrate, spaced apart from each other in a first direction, in contact with a third impurity region a fourth impurity region, which are also provided on the substrate with the second and first types of conductivity, respectively. Interconnects that extend in a second direction, which is different from the first direction, are formed in the substrate, on the side of the third impurity region facing the fourth impurity region side, and on the side of the fourth impurity region facing the third impurity region. By this means, when multiple diodes are arranged next to each other, it is still possible to prevent or substantially prevent the semiconductor device's chip size from increasing.

A trench gate silicon carbide metal oxide semiconductor field effect transistor (MOSFET) device and a fabrication method thereof. A second conductive heavily doped layer at the bottom corner of a trench gate is electrically connected to a second conductive heavily doped layer on another side edge of the trench gate through a layout design, which ensures a ground potential during voltage blocking state. This design protects the insulating layer in the trench gate and the Schottky contact in a junction barrier Schottky (JBS) diode, thereby enhancing device reliability. Moreover, in a diode operating mode, P+ on the left and right sides of the trench gate are connected to a positive potential. When the P+/N? junction is activated, the conductivity modulation can be implemented through hole injection, thereby improving the device's ability to withstand surge current impacts.
