Abstract: The present disclosure provides a silicon carbide (SiC) opto-thyristor and a method for manufacturing the same. The SiC opto-thyristor includes a SiC substrate, a SiC light emitter and a SiC light-sensitive thyristor. In the method, a SiC epitaxy is mainly formed on the SiC substrate with the doped P-type and N-type semiconductor materials to define the regions for forming the SiC light emitter and the basic structures of the SiC light-sensitive thyristor. A passivation layer is deposited. Conducting channels for the SiC light emitter and the SiC light-sensitive thyristor are formed by an etching process. After patterning a metal conductor layer, a structure of electrical contacts of the SiC light emitter and the SiC light-sensitive thyristor is formed. Then, terminals of an input voltage and an output voltage of the silicon carbide opto-thyristor are formed after a wire bonding process upon the electrical contacts. Finally, a packaging process is performed.

Abstract: A method for calibrating a linewidth measurement tool and a system for calibrating the linewidth measurement tool each employ a correction of a series of periodic actual measurements of at least one single measurement location of a topographic feature within a linewidth standard with an exponentially weighted moving average of a series of deviations of the series of periodic actual measurements from a corresponding series of regressed data points derived from mathematical regression of the series of periodic actual measurements. Such a correction provides for a more accurate calibration of the linewidth measurement tool and a more accurate measurement of linewidths within microelectronic products while employing the calibrated linewidth measurement tool.

Abstract: This invention describes a method for improving the test time for hot carrier injection effects in CMOS transistors. In conventional testing of hot carrier effects a stress voltage is applied between the drain and the source of a transistor. This stress voltage is limited by the drain to source punch-through voltage. In the enhance method described within, a substrate back bias is applied that extends the punch-through voltage and allows a higher drain to source stress voltage. With the higher stress voltage the amount of time needed to test parameter degradation caused by hot carrier injection is substantially reduced.
