    This paper presents the defect distribution and yield analysis on silicon wafer. The generation and recombination lifetime were the key parameters and obtained from the current- voltage and the capacitance-voltage of diode characteristics for forward bias. Then 3D contour maps were plotted as defect distribution and can be analyzed for the whole wafer which is useful for the yield analysis of the defects that were caused from fabrication process. © (2014) Trans Tech Publications, Switzerland.

    This paper is proposed to analyze the power loss from leakage current in p-n junctions in case of non-uniform defects. The different geometry p-n junctions have been fabricated by a standard 0.8 micron CMOS technology. The diode fabricated by the ion implantation process with two different condition. The reverse current and voltage (I-V)characteristics at varied temperature of p-n junctions have been measured. The power loss coefficient can be extracted from the leakage current versus temperature. Form the derivative of leakage current with temperature, the power loss with prediction trend curve can be obtained. © (2013) Trans Tech Publications, Switzerland.
