Abstract: A blast treatment method capable of performing blast treatment of a treatment subject with a simple structure, with high efficiency, and at low cost, while inhibiting scattering of harmful substances or the like to the outside. The method includes: inside disposing an inside explosive for blasting a treatment subject around the treatment subject; disposing an outside explosive having a detonation velocity greater than that of the inside explosive at a position outside the inside explosive; and detonating the outside explosive using an initiation device, and initiating the inside explosive by detonation of the outside explosive, thereby performing blast treatment of the treatment subject by initiation of the inside explosive.

Abstract: A field-effect transistor for nonvolatile memory holding use and a field-effect transistor for logical operation use are manufactured in the same structure on the same semiconductor substrate without separately providing manufacturing processes for the field-effect transistors for the two uses. Both a memory circuit and a logic circuit of a semiconductor integrated circuit are composed of n-channel and p-channel field-effect transistors including a memory holding material in a gate insulating structure. A logical operation state, a memory writing state and a nonvolatile memory holding state are electrically switched by controlling the level and application timing of a voltage to be applied between a gate conductor and a substrate region of the n-channel and p-channel field-effect transistors including the memory holding material in the gate insulating structure.

Abstract: A photo-FET based on a compound semiconductor including a channel layer formed on a substrate constituting a current path between source and drain electrodes, serving as part of a photodiode and a photosensitive region. A back-gate layer that serving as a substrate-side depletion layer formation layer is disposed between the substrate and the channel layer, and applies to the channel layer a back-gate bias by photogenerated carriers upon illumination. A barrier layer is disposed on the front side of the channel layer that causes one of the photogenerated carriers to run through the channel layer and other of the photogenerated carriers to sojourn or be blocked off. A front-side depletion layer formation layer is disposed on the front side of the channel layer brings the front-side depletion layer into contact with the substrate-side depletion layer without illumination to close the current path in the channel layer, bringing the photo-FET to an off-state.
