Method of manufacturing a beta-Ga.SUB.2.O.SUB.3.-based single crystal film by flowing a Ga chloride gas, an oxygen gas, and a dopant gas
A method for manufacturing a semiconductor film includes placing a semiconductor substrate including a -Ga.sub.2O.sub.3-based single crystal in a reaction chamber of an HVPE apparatus. When the semiconductor substrate is placed so that the growth base surface faces upward, an inlet for a dopant-including gas into the space is positioned higher than an inlet for an oxygen-including gas into the space and an inlet for a Ga chloride gas into the space is positioned higher than the inlet for the dopant-including gas into the space. When the semiconductor substrate is placed so that the growth base surface faces downward, the inlet for the dopant-including gas into the space is positioned higher than the inlet for the Ga chloride gas into the space and the inlet for the oxygen-including gas into the space is positioned higher than the inlet for the dopant-including gas into the space.

JBS device with improved electrical performances, and manufacturing process of the JBS device
A Junction Barrier Schottky device includes a semiconductor body of SiC having a first conductivity. An implanted region having a second conductivity, extends into the semiconductor body from a top surface of the semiconductor body to form a junction barrier diode with the semiconductor body. An electrical terminal is in ohmic contact with the implanted region and in direct electrical contact with the top surface, laterally to the implanted region, to form a Schottky diode with the semiconductor body. The implanted region is formed by a first and a second portion electrically connected directly to each other and aligned along an alignment axis transverse to the top surface. Orthogonally to the alignment axis, the first portion has a first maximum width and the second portion has a second maximum width greater than the first maximum width.
