Simulation of Light Addressable Potentiometric Sensors based on MEDICI

摘要：

Light addressable potentiometric sensors (LAPS) are the biochemically sensitive semiconductor devices. Its working principles, the charge-distribution models of the electrolyte-insulator (El) interface and its incorporation with semiconductors photoelectric effects, are summarized. Then back illuminated LAPS with the structure of Si3N.i/SiO2/Si is simulated based on MEDICI, one of Synopsys device simulation tools. The simulated results are compared with what obtained by actual measurement in two main features: characteristic curves of AC photocurrent versus DC bias voltage and the frequency of light intensity modulation. The basic accordance indicates that this MEDICI based approach may be a new possible method for LAPS simulation.
