The invention offers a magnesium alloy sheet having excellent warm plastic formability, a production method thereof, and a formed body produced by performing warm plastic forming on this sheet. The magnesium alloy sheet is produced by giving a predetermined strain to a rolled sheet RS that is not subjected to a heat treatment aiming at recrystallization. The sheet is not subjected to the foregoing heat treatment even after the giving of a strain. The strain is given through the process described below. A rolled sheet RS is heated in a heating furnace 10. The heated rolled sheet RS is passed between rollers 21 to give bending to the rolled sheet RS. The giving of a strain is performed such that the strain-given sheet has a half peak width of 0.20 deg or more and 0.59 deg or less in a (0004) diffraction peak in monochromatic X-ray diffraction. The alloy sheet exhibits high plastic deformability by forming continuous recrystallization during warm plastic forming through the use of the remaining strain.

In a manufacturing apparatus for manufacturing an epitaxial wafer with a wafer being mounted substantially concentrically with a susceptor, a center rod is provided to extend in an up-and-down direction on a side of a non-mounting surface of the susceptor so that its upper end is adjacent to the center of the susceptor. With this arrangement, part of radiation light irradiated toward the susceptor is diffusely reflected by the center rod before reaching the central portion of the susceptor, thereby reducing the amount of the radiation light irradiated to the central portion of the susceptor as well as lowering the temperature of the portion. Since the center rod and the susceptor are not in surface contact, the center rod does not take the heat from the susceptor, thereby suppressing the temperature from decreasing locally at the central portion of the susceptor.

A plurality of partial control zones (an LL zone, an LR zone, and an R zone) that can control a gas flow rate independently in a widthwise direction of a gas flow are configured on an upstream side of the gas inlet port 20B. A control device 66 is disposed to control a gas flow rate for respective partial control zones. The control device 66 obtains a deviation between a film growth rate and a predetermined target film growth rate at a variety of locations on a wafer 28 based on the data of a thickness of a film that has been formed on the wafer 28 by a rotating film formation carried out while rotating the wafer 28, and controls the respective gas flow rates of the partial control zones by using the rotation film growth sensitivity data 72 that defines a sensitivity to a change in a film growth rate distribution during the rotating film formation on the wafer 28 in such a manner that a change in the respective gas flow rates of the partial control zones causes the deviation at a variety of the locations to be reduced.

A high-sensitivity field effect transistor using as a channel ultrafine fiber elements such as carbon nanotube, and a biosensor using it. The field effect transistor comprises a substrate, a source electrode and a drain electrode arranged on the substrate, a channel for electrically connecting the source electrode with the drain electrode, and a gate electrode causing polarization due to the movement of free electrons in the substrate. For example, the substrate has a support substrate consisting of semiconductor or metal, a first insulating film formed on a first surface of the support substrate, and a second insulating film formed on a second surface of the support substrate, the source electrode, the drain electrode, and the channel arranged on the first insulating film, the gate electrode disposed on the second insulating film.
