Experimental results of the IGBT turn-on characteristics using 1200 V/50 A Trench Oxide PiN Schottky (TOPS) diode as the free wheeling diode are described. Compared to the conventional PiN diode, the TOPS diode showed an approximately 25% reduction in the turn-on loss of the IGBT. A reduction of 40% in the peak collector current of the IGBT has been achieved which results in a substantial suppression in the noise emission.
A novel backend process is developed for the cylindrical ru/Ta/sub 2/O/sub 5//ru capacitor for 130 nm generation drAMs to achieve good electrical characteristics. Forming gas (3%H/sub 2//97%N/sub 2/) anneal (FGA) indu...

A novel backend process is developed for the cylindrical ru/Ta/sub 2/O/sub 5//ru capacitor for 130 nm generation drAMs to achieve good electrical characteristics. Forming gas (3%H/sub 2//97%N/sub 2/) anneal (FGA) induceddegradation can be effectively suppressed. For the cylindrical ru/Ta/sub 2/O/sub 5//ru capacitor with full backend processes, including passivation layer formation and a FGA, the cell leakage current and cell capacitance are 1 fA (at /spl plusmn/0.8 V at 85/spl deg/C) and 15fF, respectively.

This paper presents the design of an H/sub /spl infin// basedrobust static synchronous series compensator (SSSC) supplementary controller to suppress the subsynchronous resonance (SSr) in the series-compensated system. The modified IEEE second benchmark, System-1 model is employed for this study. In order to design the effective controller, the modal observability to the oscillation modes is considered. Comprehensive time domain simulation studies using the nonlinear system model show that the proposed H/sub /spl infin// SSSC supplementary controller can suppress the SSr efficiently in spite of the variations of power system operating conditions.

Summary form only given. In consumer electronics, cost-effective embeddedtechnology is an important subject. We propose a novel, cost-effective gain cell for memory embedded in logic LSIs. The new cell consists of two conventional bulk transistors and one MOS capacitor. It can be fabricated using the pure logic process with a few additional process steps. The fabrication cost of this cell is lower than that of drAM or SrAM at a memory density in the 1/spl sim/100 Mbit range.

A novel shallow trench isolation (STI) technique named Poly-Si-Buffered-mask STI (PB-STI) using the SiN/poly-Si/SiO/sub 2/ stacked mask has been proposed. The poly-Si is oxidized at the step of liner oxidation and then a "small bird's beak" is grown. With small bird's beak formation the oxide recess at the trench edge is prevented and the fringing of electric-field from the gate electrode can be effectively avoided. PB-STI can completely suppress the inverse narrow channel effect with quite simple process sequence which includes no corner implantation.

An MPEG-2 4:2:2@HL encoder chip set will be presented. It is composed of an encoder LSI [COd-LSI], a preprocessor LSI [PP-LSI], and a motion estimation LSI [ME3-LSI]. Scalable architecture allows a cascadable configuration for higher picture quality and higherresolutions. The encoder LSI, which is the key to this chip set, employs advanced hybrid architecture with a 162 MHz media-processor core [d30V] anddedicated video processing hardware. It also has dual-communication-ports for a multi-chip configuration. With above architecture, a single encoder LSI can perform SdTV encoding, and only six chips can perform HdTV encoding.
