We have developed a Java-based novel system called NILE, which is tolerable for practical use and working on a distributed environment for semiconductor process anddevice simulations. NILE enables the utilization of simulation in practical use from remote sites even if the network bandwidth is narrow. NILE has succeeded in providing the same kind of simulation environment regardless of the kinds of platforms. Furthermore, NILE enables developing devices for USLI much more efficiently using the central servers.

A novel integration technology with capacitor over metal (COM) for 0.15 /spl mu/m stand-alone and embeddeddrAMs is developed using a self-aligneddual damascene (SAdd) process, which offers great breakthroughs. First, many back-end metallization issues encountered in conventional COB (capacitor over bit line) drAMs are simply overcome because the capacitor is formed after the metal lines. Secondly, memory cell capacitors can be integrated much more simply and easily compared to those of conventional COB technology because the memory cell contact and storage node are formed simultaneously. Furthermore, transistor performance can be greatly improved because a novel poly-Si/Al/sub 2/O/sub 3//poly-Si capacitor is integrated at temperatures below 400/spl deg/C.

The Japanese Association for Electrical Home Appliances (AEHA) has developed an integratedrecycling system for four large domestic appliances. As the member companies of the project, subsidized by Ministry of International Trade and Industry (MITI), the authors developed an artificial intelligence (AI) system to control the plant for laborreduction and automatic treatment. Environmental assessment on the operating condition of the plant can be executed through the AI system.

This paperdescribes a 16:1 multiplexer (MUX) using a 0.18 /spl mu/m partially-depleted SOI-CMOS technology. Owing to a selector type architecture with a pipeline structure as well as small junction capacitances of SOI-CMOS devices, the MUX achieves 3.6 Gbps operation dissipating 340 mW at a power supply of 2.0 V.

A low resistance salicided 0.1 /spl mu/m CMOSFET has been developed with precisely controlled T-shaped gate and optimum gate structure for thick CoSi/sub 2/. Selective Si growth (SSG) using a SiO/sub 2/-SiN stacked sidewall with the exposed SiN top hill enables suppression of junction leakage for thick Co silicidation, to eliminate bridging between gate and source/drain (S/d), and to precisely control the extra gate length for T-shaped gates. Moreover, the nitrogen profile in the p/sup +/ gate is optimized to suppress gate depletion induced by the thick Co. Since a heavily nitrided gate oxide insulator and N implantation of the poly-Si surface can prevent gate-implanted B ions from being diffused into the substrate and into the CoSi/sub 2/ layer, an increase in the gate sheet resistance, B penetration, and gate depletion can be simultaneously resolved, and thus high performance 0.1 /spl mu/m CMOS can be achieved with gates of as low as 1.9 /spl Omega//sq. sheet resistance.

We proposed the Ta–ruO2 diffusion barrier for oxygen in the dynamic random access memory capacitor bottom electrode, and investigated the barrier and electrical properties of the developeddiffusion barrier. The Ta–ruO2/TiSi2/poly-Si/SiO2/Si contact system deposited with and without the SiO2 capping layer showed the lower total resistance and ohmic characteristics up to 800 °C. For the Ta–ruO2/TiSi2/poly-Si/SiO2/Si contact system, no other phases observed except for the formation of conductive ruO2 phase in the barrier film by reaction with the indiffused oxygen after annealing in air, but the thin oxidized layer at the Ta–ruO2/TiSi2 interface was formed by external oxygen. However, a large number of the crystallites in the annealed samples compared to that of as-deposited film were observed even afterdepth profile. The crystallites consisted of ru and O containing a small amount of Ta. In addition, the embeddedruO2 crystalline phase was observed in the thin oxidized TiSi2 surface layer. Correspondingly, we suggest that the ohmic mechanism of the Ta–ruO2/TiSi2/poly-Si/SiO2/Si contact system is an embeddedruO2 crystalline phase involving a small amount of Ta in a Ta amorphous structure.

We developed a hole shrink process namedrELACS (resolution Enhancement Lithography Assisted by Chemical Shrink) that is a robust and low-cost method. This method makes use of crosslinking reaction between the materials coated on the resist pattern, and the acid existing at the resist wall. By the rELACS, we could shrink KrF resist hole patterns to 0.1 /spl mu/m level. The shrinkage of hole size is dependent on both baking temperature and initial hole size. This process has been established for the fabrication of 0.20 /spl mu/m devices.

A high performance 0.18 /spl mu/m CMOS logic device has been developed with 0.15 /spl mu/m transistors and six-level interconnects. The multi-level interconnect system consists of a conventional process with Al wire and a dual damascene process with Cu wire. 4-level Al interconnects with fine metal pitch are suitable for short distance wiring such as intra block cell to cell interconnects, whereas 2-level Cu interconnects with coarse metal pitch are used for long distance wiring such as mega block to block interconnects to achieve high-speed and high-density LSI devices.

The Pt/Ta diffusion barrier using hybrid conductive oxide (ruO2) fordynamic random access memory and ferroelectric random access memory capacitor bottom electrodes is proposed. The thermal stability of Pt+ruO2 (50 nm)/Ta+ruO2 (50 nm)/TiSi2/poly-Si/SiO2/Si contact system is investigated and compared to that of the Pt(50 nm)/Ta(50 nm)/TiSi2/poly-Si/SiO2/Si contact system. The Pt+ruO2/Ta+ruO2/TiSi2/poly-Si/SiO2/Si contact system sustained its structure up to 650 °C, whereas Pt/Ta/TiSi2/poly-Si/SiO2/Si contact system was completely degraded after annealing at 650 °C. In the former case, the addition of ruthenium dioxide (ruO2) into the Pt bottom electrode layer led to retardation of the oxygen indiffusion, preventing the indiffusion of oxygen up to 650 °C. In addition, the Ta+ruO2 diffusion barrier showed an amorphous structure andruO2 is bound to the Ta matrix, inhibiting the interdiffusion of O, Pt, and Si through grain boundaries which can act as fast diffusion paths up to high temperatures. Therefore, it appeared that the barrier properties of Pt/Ta diffusion barrier are improved by using hybrid conductive oxide (ruO2).
