Title: Method for measuring the width of electron beam pulse
Inventor: ITO AKIO
IPC: H01J37/28
Filed: 1985-08-20
Abstract: PURPOSE:To accurately measure the width of a short pulse by irradiating an electron beam pulse upon the internal area of a Faraday cage many times to obtain the total amount of electron beam irradiation and calculating the width of the electron beam pulse from the frequency of irradiation and the peak current of the beam. CONSTITUTION:After a Faraday cage 50 is placed instead of a test substance, an electron beam pulse 5 is irradiated upon the internal area of the cage 50 many times and the minute current flowing through an SW1 is measured by an amperemeter 51. The amount of electric charge accumulated in the cage 50 is obtained from the product of the frequency of projection of the pulse 5, the pulse time and the current level of an amperemeter 51. Next, secondary electrons produced by applying the electron beam to the outer surface of the Faraday cage 50 are detected and the voltage of the cage 50 is measured by a voltage-measuring circuit 13. Since the product of the capacity and the electric potential of the Faraday cage 50 corresponds to the electric charge, the width of a very short pulse can be easily measured with high S/N ratio by inverse operation.

Title: Temperature control device for thermal analysis
Inventor: NAKAMURA NOBUTAKA
IPC: G01N25/00
Filed: 1985-08-20
Abstract: PURPOSE:To consume electric power within the range of electric power source capacity by comparing and supervising always the sum of the maximum power consumption of the heating furnace with the electric power source capacity, and when the maximum power consumption exceeds the electric power source capacity, preventing the starting of the measurement. CONSTITUTION:Heating furnaces 1a, 1b and 1c are connected to a temperature control device 2. The maximum power consumption of these heating furnaces is sent to the device 2 as analog voltages Va, Vb and Vc by the suitable conversion, detected by electric power detecting devices 3a, 3b and 3c and thereafter, inputted to an adder 4. An output Vmax(=Va+Vb+Vc) of the adder 4 is compared with the voltage Vref converted from the electric power value inputted by an electric power value input device 5 by a comparator 6. When the maximum power consumption is larger than the input electric power value as the result of the comparison by the comparator 6 (Vmax>Vref), the error signal is sent to heating furnace control circuits 7a, 7b and 7c. The circuits 7a, 7b and 7c are constituted so as not to be operated, when the error signal enters from the comparator 6, even if starting switches 8a, 8b and 8c are operated.

Abstract: PURPOSE:To form a thin film semiconductor device by conducting a pressure- reduced chemical vapor phase deposition method by differentiating the chemical composition of the semiconductor film for film thickness direction. CONSTITUTION:After a silicon dioxide film 202 and a source/drain region 203 have been formed on a substrate 201, an intrinsic silicon film is deposited using an LPCVD device, and then a silicon film is formed by implanting phosphoric ions. When the intrinsic silicon film, which becomes a source/drain region, is deposited by an LPCVD device, the intrinsic silicon film is preferentially oriented on a [220] surface perfectly. Then a semiconductor film 204, which becomes a transistor active layer, is deposited by the LPCVD device. Subsequently, when a silicon film is deposited as a first semiconductor film under the same condition as the intrinsic silicon film, the crystal condition of the first semiconductor film is preferentially oriented on the [220] surface. When the second semiconductor film is formed continuously without a break, the crystal condition is substantially oriented to [111] surface. When a channel part 205, which becomes an active layer, is formed by patterning, a semiconductor device of high mobility can be formed at a low temperature.
