A wearing band has an extending section and a movable section that is movable relative to the extending section in the length direction of the wearing band. A locking mechanism is capable of switching the wearing band between an unlocked state in which the movements of the movable section in the extending direction in which the length of the wearing band is increased and in the retracting direction in which the length of the wearing band is decreased are allowed and a locked state in which the movement of the movable section in the extending direction is restricted. The movable section is urged at least in the retracting direction in an unlocked state.

There is provided a head-mounted display which allows the lengths of fastening bands to be adjusted easily and can be mounted on the head of the user with increased stability. The head-mounted display has a first fastening band and a second fastening band which extend from the front side toward rear side thereof, for being fastened to the head of the user. At least a portion of the first fastening band is made of an elastically expandable material. The second fastening band is made of a material which is less expandable than the material of the first fastening band and includes a mechanism for adjusting the length thereof.

An object of the invention is to minimize variation in characteristics of a vertical bipolar transistor. An insulating side wall spacer composed of a silicon nitride film and a silicon oxide film is formed on the side surface of an opening formed in a base electrode polysilicon film . The thickness (&equals;W ) of the insulating side wall spacer is made thicker than the maximum thickness (&equals;W ) within a range of variation in thickness of a polycrystalline film grown from the side surface of the base electrode polysilicon film exposed inside the opening (namely, W >W ). The size of an opening for forming an emitter electrode polysilicon film on an intrinsic base is not influenced by the thickness of a polycrystalline film epitaxially growing from the side surface of the polysilicon film for the base electrode, but is defined by the side wall spacer formed on a portion of the side surface of the base electrode polysilicon film. Therefore, emitter area hardly disperses, and electric characteristics become stable.
