Using known experimental results, a semiempirical relation for carrier mobility (/spl mu/) dependence on electric field intensity, dopant concentration and temperature was formulated. Based on this relation appropriate analytical mathematical-physical model for simulation of current-voltage characteristics, transconductance and conductance of MOSFET were developed. All models were formulated taking into account, among other effects, the dependence of threshold voltage on temperature and impurity concentration in the channel, as well as the effect of the channel narrowing. Using the proposed model a simulation algorithm was designed and a simulation of the MOSFET's performance was performed. Results of the simulation are graphically presented in and discussed.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics. Proceedings (Cat.

Low pressure metalorganic chemical vapor deposition (MOCVD) technology was used for the modification of the effective Schottky barrier height by means of precise /spl delta/-doping of near-surface layer and for successive deposition of an aluminium film in non-interrupted growth run. A complete quantum-mechanical numerical simulation of the effect produced by /spl delta/-doping on the current-voltage characteristic of the modified diodes is carried out. Comparison of computational results with the experimental characteristics of diodes shows a rather good agreement. Analysis of the carried-out research has allowed one to choose optimum parameters of /spl delta/-layers for producing low barrier diodes (/spl sim/0.2 eV) with a reasonable ideality factor (n<1.5). The best performance of the low barrier diode corresponding to /spl gamma/=5000 V/W and NEP=(3/spl divide/6)/spl middot/10/sup -12/ W/spl middot/Hz/sup -1/2/ at 150 GHz was at zero bias voltage.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics.

FSM non-minimal state encoding for low power 低功耗FSM非最小状态编码

In contrast to many publications where probabilistic approach to power estimation is offered, we consider power measurement based on given user-specified input sequence. Although the power dissipation depends on several parameters (register and output switching activity, complexity of combinational part, capacitance load on the gate), switching is the most important source of power dissipation. Our goal is to develop an encoding procedure which minimizes register switching activity. We start with a highly redundant (seed) encoding and minimize its length while minimizing the register switching activity. Unlike previous works, we don't restrict encoding final length (only register switching activity is considered). Therefore, final encoding length may differ from the minimal one. We tested our encoding procedure on several benchmarks from the MCNC set. The experiments show that in many cases, power dissipation obtained using our encoding (generally, of non-minimal length) is less than one achieved when encoding of minimal length is generated.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics.

The measurement allows one to determine energy level of dominant recombination centres and evaluate their concentration. The carrier lifetime in volume of the cell body can be evaluated using local irradiation of the surface of large-area solar cells with a laser diode (/spl lambda/=870 nm) from measured values of open circuit voltage V/sub oc/. The method can give information about recombination centres distribution in large-area solar cells. From V/sub oc/ distribution, position and extent of local defects can also be determined. Solar cell diagnostic methods can be used to investigate the influence of technology on characteristics of solar cells, with the aim of increasing efficiency and reliability of solar cells.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics.

We proposed a simple amplitude calibration to strongly reduce nonlinearity coming from misalignment to 0.3% of the full scale. Additional nonlinearity from Hall elements has been discussed.
