    摘要: A thin film forming apparatus using laser includes a chamber (1), a target (5) placed therein, a laser light source (10) for emitting laser beam to target (5), and a substrate holder (3). When target (5) is irradiated with laser beam (16), a plume (15) is generated, and materials included in plume (15) are deposited on the surface of a substrate (2) held by substrate holder (3). The laser beam emitted from laser light source (10) has its cross section shaped to a desired shape when passed through a shielding plate (4804), for example, so that the surface of the target (5) is irradiated with the beam having uniform light intensity distribution. Therefore, a plume (15) having uniform density distribution of active particles is generated, and therefore a thin film of high quality can be formed over a wide area with uniform film quality, without damaging the substrate.

    摘要: In a MOSFET using SiC a p-type channel is formed by epitaxial growth, so that the depletion layer produced in the p-type region right under the channel is reduced, even when the device is formed in a self-aligned manner. Thus, a high breakdown voltage is obtained. Also, since the device is formed in a self-aligned manner, the device size can be reduced so that an increased number of devices can be fabricated in a certain area and the on-state resistance can be reduced.

    摘要: A semiconductor device and its manufacturing method are provided in which the trade-off relation between channel resistance and JFET resistance, an obstacle to device miniaturization, is improved and the same mask is used to form a source region and a base region by ion implantation. In a vertical MOSFET that uses SiC, a source region and a base region are formed by ion implantation using the same tapered mask to give the base region a tapered shape. The taper angle of the tapered mask is set to 30° to 60° when the material of the tapered mask has the same range as SiC in ion implantation, and to 20° to 45° when the material of the tapered mask is SiO2.
