This paper discusses modeling of non-uniform substrate re-sistivity for substrate resistance extraction. Though substrate resistivity of each substrate layer is frequently assumed to be uniform, doping profile of each substrate layer is not uniform. We present the extraction error of substrate resistance under uniform resistivity assumption. The resistivity(More)
This paper suggests the modeling methods of non-uniform substrate resistivity for substrate resistance extraction. Conventional substrate model of uniform resistivity for each substrate layer can cause about 40-80% resistance extraction errors. Though model of simulated doping profile theoretically provides fine accuracy, the doping profile cannot be(More)
The surface velocity of natural debris flows is one of the main physical parameters for developing effective disaster prevention techniques. The authors already presented the result of velocity vector field measurement of debris flow by the spatio temporal derivative space method. In this paper, we propose a multi resolution spatio temporal derivative space(More)
