Abstract: An embodiment relates to a n-type planar gate DMOSFET comprising a Silicon Carbide (SiC) substrate. The SiC substrate includes a N+ substrate, a N? drift layer, a P-well region and a first N+ source region within each P-well region. A second N+ source region is formed between the P-well region and a source metal via a silicide layer. During third quadrant operation of the DMOSFET, the second N+ source region starts depleting when a source terminal is positively biased with respect to a drain terminal. The second N+ source region impacts turn-on voltage of body diode regions of the DMOSFET by establishing short-circuitry between the P-well region and the source metal when the second N+ source region is completely depleted.

Abstract: The present invention is an apparatus and method for cutting individual label strips from a roll of label web utilizing a cutter assembly. A label cutter comprises a cutter assembly for continuously and independently controlling the rotational speeds of a rotating cutter shaft, a stationary shaft, and a label feed roller is provided. The length of the label strip is controlled by the distinct speed of rotation of a stationary knife, the stationary knife is rotatably coupled to the stationary shaft. At least one cutter blade is operatively associated to the rotating cutter shaft for cutting the label web. The stationary knife rotates with a to speed of rotation different from the speed of rotation of the cutter blade to produce longer or shorter label length strips. The frequency at which the cutter blade meets the stationary knife is inversely related to the length of the label strip that is produced during cut off.
