In this paper, tension-torsion-bending combined loading test technique for microscale single crystal silicon beam specimens is described. We have designed and developed two types of the multi-deformation loading test apparatuses to investigate the deformation-mode and specimen-size dependencies on the fracture strength. The comparisons among the strength data under different deformation-modes and...
In this article, the influences of specimen size and deformation-mode on the fracture strength of single-crystal silicon (SCS) micro-beam structures are described. We have designed and developed a new materials test device that is able to apply pure torsion, torsion-bending-combined, and bending deformations to a micro-scale beam specimen. The differences in deformation-mode are determined by loading...
A new sense device structure is proposed for hybrid IGBTs in which current sensing ratio (CSR) is constant for a wide range of collector currents (ICE)- Hybrid IGBTs are a new type of switching device, with 2 operation modes: MOS operation mode at low ICE and IGBT operation mode at high ICE. Although the current flow mechanism is different between the two modes, it is preferable that CSR in both MOS...
A new lateral 800 V hybrid IGBT with a high-speed internal diode is proposed for switch-mode power supply (SMPS) applications. The hybrid IGBT operates as a MOS only when the collector/drain current is small. Then, the device shifts to IGBT operation with an RonA of 72 mOmegacm2 when the collector voltage is 6 V. The switching speed of the device is made fast enough to turn off in around 100 nsec,...
Current induced magnetic field over a metal nanostructure was investigated by using magnetic force microscopy (MFM) to discuss the spatial resolution and the detection current limit in measuring current distribution in a polycrystalline-Si (poly-Si) layer of thin film transistors. It was found that the detection current limit depended on the MFM probe height, which is a separation between the tip...
In fracture healing, a large amount of cartilage is formed, then rapidly replaced by osseous tissue. This process requires the transition of extracellular matrix component from type II to type I collagen. We investigated the expression of matrix metalloproteinase-13 (MMP-13), which has a high potential to cleave type II as well as type I collagen, during fracture repair in mouse ribs. In situ hybridization...
