This research was conducted to study the effect of strain silicon on 90nm PMOS using graded silicon germanium (SiGe). By introducing graded silicon germanium layer under the gate oxide, the performance of conventional 90nm PMOS and 90nm PMOS with silicon germanium layer was compared. The analysis focused on Id-Vg, Id-Vd characteristic, and hole mobility changes. TCAD SILVACO simulator was used to...
Automotive suspension systems have big potential of mechanical failure due to fatigue as this system was subjected to the variable amplitude loading under service condition. This study was specifically focuses on coil spring, one of the suspension system parts. When vehicle was driven on any road surfaces and hit potholes or bump, this coil spring is then affected by the significant load. This significant...
Almost all of factories use failure mode and effect analysis (FMEA) technique to reduced risk priority number (RPN). This paper proposes a new model to reduce RPN by improving overall equipment efficiency (OEE) by using of heuristic mathematic model based on total productive maintenance index. Three factors are considered: (i) probability of failure (Occurrence), (ii) severity and (iii) distinction...
This paper provides a new approach to evaluate the transistor safe operating area for a nonlinear operation in the overdrive operating conditions. This approach has been implemented for a MESFET technology. The methodology consists in performing ON-state and OFF-state accelerated DC step stresses for bias conditions, which can be reached by VDS and VGS sweeps in the overdrive operating conditions...
