Semiconductor integrated circuit device

Abstract: A semiconductor integrated circuit device includes a plurality of internal memories, a main processor, which constitutes a first processing unit having a codec function, and a video interface and graphics processor, which constitute a second processing unit for video display processing. The semiconductor integrated circuit device operates while being connected to a CPU, which is an external processing unit, and an external memory. The semiconductor integrated circuit device is provided with a memory configuration controller for controlling the memory allocation to the first, the second, and the external processing unit in accordance with an application.

GaN on Si Technologies for Power Switching Devices

Abstract: This paper reviews the recent activities for normally-off GaN-based gate injection transistors (GITs) on Si substrates and their application to inverters. Epitaxial growth of the AlGaN/GaN heterostructures with good crystallinity over 200-mm Si substrates with eliminated bowing enables low-cost fabrication of GaN devices with high breakdown voltages. A novel normally-off GaN transistor called as GIT is proposed in which hole injection from the p-type AlGaN gate increases the drain current with low on-state resistance by conductivity modulation. The low on-state resistance in GaN-based devices greatly helps to increase the efficiency of power switching systems. A GaN-based three-phase inverter successfully drives a motor with high efficiency of 99.3% at a high output power of 1500 W. The presented GaN-based devices are expected to greatly help saving energy in the future as an indispensable power switching system.

Battery module and battery assembly used in battery module

Abstract: A battery module includes a plurality of battery assemblies stacked together. Each of the battery assemblies includes an insulating case which accommodates a plurality of cells. A first connection plate connects the same polarities of the cells, and a second connection plate connects polarities opposite the same polarities of the cells. The first connection plate includes a first connection terminal which protrudes in a direction opposite a direction toward the second connection plate. The second connection plate includes a second connection terminal which protrudes in a direction toward the first connection terminal. The first connection terminal protrudes outwardly of the case. The second connection terminal protrudes inwardly of the case. In the battery assemblies adjacent to each other in a stacking direction, the first connection terminal of one battery assembly and the second connection terminal of the other battery assembly are fitted to each other. The first connection terminal of one battery assembly protrudes inwardly of the case of the other battery assembly.
