In a camara exterior part according to the present invention, a front mold member having in one piece a reinforcing portion for preventing deformation is formed using a resin by injection molding. The front mold member is fixed to the inner surface of a front cover made of a metal by adhesion. After the fixing, the reinforcing portion is cut and removed from the front mold member. According to the present invention, high-accurate assembly can be easily realized with a simple arrangement.

A dielectric plate 20 is provided at a ceiling surface facing a susceptor 3 of a processing chamber 2, and a slot antenna 30 having a multiple number of microwave transmissive slots 33 is provided on a top surface of the dielectric plate 20. A protrusion member 21 configured as a separate member from the dielectric plate 20 is provided on a peripheral portion of a bottom surface of the dielectric plate 20 so as to prevent an abnormal electric discharge. Electric field intensity in the vicinity of the dielectric plate 20 is controlled by adjusting a gap between an outer peripheral surface 22 of a cylindrical part of the protrusion member 21 and an inner peripheral surface 5a of a sidewall of the processing chamber 2 or by adjusting a thickness of the cylindrical part of the protrusion member 21.

A nitride semiconductor device includes a main surface and an indicator portion. The main surface is a plane inclined by at least 71° and at most 79° in a [1-100] direction from a (0001) plane or a plane inclined by at least 71° and at most 79° in a [−1100] direction from a (000-1) plane. The indicator portion indicates a (−1017) plane, a (10-1-7) plane, or a plane inclined by at least −4° and at most 4° in the [1-100] direction from these planes and inclined by at least −0.5° and at most 0.5° in a direction orthogonal to the [1-100] direction.

A level switch circuit receives a digital input signal, and generates a level signal having a voltage level that corresponds to the value of the input signal thus received. A buffer circuit receives a level signal, and outputs the level signal via an output terminal thereof. A bias current generating circuit generates a bias current including a DC component having a constant level and a variable component that changes according to the input signal, and supplies the bias current thus generated to a buffer circuit. The bias current generating circuit detects an edge of the input signal, and raises the bias current by a predetermined amount for a predetermined period of time after the edge thus detected.

The present invention provides a substrate formed at a low cost and having a controlled plate shape, an epitaxial layer provided substrate obtained by forming an epitaxial layer on the substrate, and methods for producing them. The method for producing the substrate according to the present invention includes an ingot growing step serving as a step of preparing an ingot formed of gallium nitride (GaN); and a slicing step serving as a step of obtaining a substrate formed of gallium nitride, by slicing the ingot. In the slicing step, the substrate thus obtained by the slicing has a main surface with an arithmetic mean roughness Ra of not less than 0.05 μm and not more than 1 μm on a line of 10 mm.
