Based on theoretical considerations and measurements of the number of self-interstitial clusters during a thermal step we were interested in finding a suitable model for the formation and dissolution of self-interstitial clusters and extracting corresponding model parameters for two different technologies (i.e., material parameter sets). In order to automate the inverse modeling part a general optimization framework was used. Additional to solving this problem the same setup can solve a wide range of inverse modeling problems occurring in the domain of process simulation. Finally the results are discussed and compared with a previous model.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics. Proceedings (Cat.

The gate oxide degradation due to hot carrier generation is inherently eliminated. The metalization on the wafer back includes copper electroplating. A thick copper layer on the wafer back serves as an excellent heat spreader and heat sink. Moreover, it can be used to avoid debiasing due to voltage drops over the metalization. The device performance has been investigated using DC and AC MEDICI simulations and the \"Smoothie\" database model for FET devices.

Two buffers of unity-gain split up the bootstrap loop. PSPICE simulations with real transistor parameters demonstrate the advantages of the new circuit. The T&H waveforms of 5 MHz and 35 MHz input 2 V swing signal, sampled at 80 MHz, are shown.

We investigated all of the main properties of our detectors, including current-voltage characteristics, sensitivity, spectral noise, specific detectivity (D*) and response time. In our calculations we used our generalized expression for the absorption coefficient of HgCdTe that takes into account the influence of non-quantizing magnetic fields.

We show that the symbol-parallel Fitzpatrick algorithm for solving the key equation uses 30% fewer multipliers than Berlekamp-Massey type architectures, thus achieving a cost reduction for the entire codec.
