Abstract: A process for manufacturing a bipolar type semiconductor device in which at least a part of a region where an electron and a hole are recombined during current flowing is formed with a silicon carbide epitaxial layer that has been grown from the surface of a silicon carbide substrate, is characterized by that the surface of the silicon carbide substrate is treated by hydrogen etching and the epitaxial layer is then formed by the epitaxial growth of silicon carbide from the treated surface. A propagation of a basal plane dislocation to the epitaxial layer can be further reduced by treating the surface of the silicon carbide substrate by using chemical mechanical polishing and hydrogen etching in this order.

Abstract: When there is a difference in moving speed of an endless belt in a widthwise direction, a printing sheet fed by this endless belt becomes inclined, and a pattern to be printed becomes inclined or distorted. To deal with this problem, a first detector for detecting moving speed is formed on one side edge of the endless belt, and a second detector for detecting moving speed is formed on the other side edge belt. Standard time is determined on the basis of a difference between the values detected by the first and the second detectors. The standard time is determined for each position along the width of the endless belt. Ink discharging time for each ink jet nozzle is determined on the basis of the standard time that has been determined, and on the basis of a pattern to be printed. The effects of the inclination of the printing sheet can be cancelled out, and a printed pattern can be obtained that is the same as when printing on a sheet that was not inclined.
