A synchronous motor includes a stator, a rotor and permanent magnets. The rotor includes a rotor iron core and rotatable relative to the stator, a plurality of conductor bars accommodated within corresponding slots in the rotor iron core. The conductor bars have their opposite ends shortcircuited by respective shortcircuit rings to form a starter squirrel cage conductor. The rotor also have a plurality of magnet retaining slots defined therein at a location on an inner side of the conductor bars, in which hole permanent magnets are embedded.

Provided is a CdTe-based semiconductor substrate for epitaxial growth, which is capable of growing good-quality epitaxial crystals without urging a substrate user to implement etching treatment before the epitaxial growth.A CdTe-based semiconductor substrate, in which tracks of linear polishing damage with a depth of 1 nm or more are not observed within a viewing range of 10 μm×10 μm when a surface of the substrate is observed by an atomic force microscope, and orange peel defects are not observed when the surface of the substrate is visually observed under a fluorescent lamp, can grow the good-quality epitaxial crystals.

A heat treatment apparatus includes a support sheet placed on an upper surface of a heat-treating plate. The support sheet has, formed on an upper surface thereof, projections for contacting and supporting a substrate, and a lip for contacting edge regions of the substrate. The support sheet is formed by an etching process, and therefore areas of the sheet around the projections are recessed, rather than being perforated as in the case of laser processing. These heat-treating plate and support sheet constitute a substrate support structure capable of supporting the substrate properly.

A substrate processing apparatus and a thermal processing apparatus are capable of creating a pattern with an excellent line width uniformity. An ACU conditions air to a temperature and a humidity which are suitable to processing which uses a resist of chemical thickening type, while an ammonia removing filter removes an ammonia component from the air and the air is supplied to an air supply pipe which branches off. A pump, a flow meter and a pressure regulator are disposed to an air supply pipe, so that the air from the ACU, as it is conditioned to flow at a constant flow rate and with a pressure, is supplied to a PEB bake unit. Since the temperature and the humidity of an atmosphere within the PEB bake unit stabilize at values which are suitable to processing which uses a resist of chemical thickening type, it is possible to form a pattern with an excellent line width uniformity. At the same time, it is possible to suppress a development failure since the atmosphere contains a reduced quantity of ammonia component.

A synchronous motor includes a stator, a rotor and permanent magnets. The rotor includes a rotor iron core that is rotatable relative to the stator, and conductor bars accommodated within corresponding slots in the rotor iron core. The conductor bars have their opposite ends short-circuited by respective shortcircuit rings to form a starter cage conductor. The rotor also has a plurality of magnet retaining holes defined therein, in which permanent magnets are embedded. The conductor bar holes are positioned in an axial direction and inwardly from the magnet retaining holes. The conductor bars within the holes protrude outwardly from an axial end of the rotor iron core to form projections for securing an end plate to the end of the rotor iron core, the end plate comprising a non-magnetizable material.
