SEM, EDX and 155 Wright etch techniques were used to identify the root causes. Cross sectional results found the nodules on substrate at the contact area. EDX analysis confirmed them to be silicon nodules. After 155 Wright etch [100] square silicon crystalline hillocks were found on the substrate at the contact area. It is concluded that silicon nodules on the substrate at the contact area had resulted in an open circuit and low yield. These silicon nodules were due to Si precipitation on the substrate of the contacts.","PeriodicalId":356206,"journal":{"name":"ICSE'98. 1998 IEEE International Conference on Semiconductor Electronics.

GaAs MMIC technology is ideally placed to meet these requirements, bringing with it small size and weight, low cost and inherent reproducibility.

However, by using the signature analysis method, the transistor failure cell can be identified by directly measuring the transistor parameters from the isolated SRAM cell. The cell isolation technique for signature analysis is sensitive enough to capture the abnormal electrical signature of the SRAM cell cold failure. The technique was used on the analysis of SRAM cell cold failure from a 2-layer metal fab process. The SRAM cell and its transistors were physically and electrically isolated without any problem. The failure signature of the SRAM cell cold failure which failed stuck at \"1\" at a single bit address during testing, was successfully analyzed. N+ drain junction leakage and threshold voltage degradation was identified as the root cause of the cold failure.","PeriodicalId":356206,"journal":{"name":"ICSE'98. 1998 IEEE International Conference on Semiconductor Electronics.

Knowledge of these parameters will enable a better design of EDFAs for operation as a power amplifier. In this saturated regime, gain saturation is defined as the gain at 3 dB gain compression from the unsaturated gain for a specific fibre length and pump power. Therefore, the output saturation power, P/sub osat/, and input saturation signal power, P/sub isat/, are defined as the output power and input signal power at which gain saturation occurs.

A new approach applying transmission line techniques is introduced to study the time evolution of the electron wave function localized in a trap quantum well in the MOS device oxide. Treating it as a one dimensional problem, with tunneling probabilities through both oxide/metal and oxide/semiconductor interfaces, and exploiting the effective similarity with the time evolution of an electron wave packet localized in a double barrier quantum well, a model is developed to calculate the lifetime of a trapped electron under flat band conditions. It is further extended to calculate the effective lifetime of electrons trapped at various trap centers in the oxide layer under externally applied electric fields. Results thus obtained show reasonable agreement and consistency with physical concepts and experimental observations.","PeriodicalId":356206,"journal":{"name":"ICSE'98. 1998 IEEE International Conference on Semiconductor Electronics.
