Title: Controlling method for electron beam irradiation device
Inventor: MIZUSAWA KENICHI
IPC: H01J37/248
Filed: 1992-05-27
Abstract: PURPOSE:To generate an electron beam immediately after extinction of a spark so that operation of an electron beam irradiation device can be restarted by fixing the output of a filament power source when detecting generation of the spark, and also restricting the output of a DC high voltage power source. CONSTITUTION:When a spark is generated in the accelerating chamber of an electron beam irradiation device 1, a current from a DC high voltage power source 4 is dropped sharply. A detector 6 detects this drop and then the output of a filament power source 2 is fixed via a filament power regulator 3. Simultaneously, the output of the power source 4 is restricted via a power regulator 5 so that the spark is extinguished. After the spark has been extinguished the outputs of the power sources 2, 4 are similarly restored and an electron beam is immediately produced so that operation of the system can be restarted; since the power sources 2, 4 are not turned off, the time required for restarting the operation is remarkably shortened.

Title: Manufacture of thin single-crystal semiconductor film
Inventor: HAYAFUJI TAKANORI
IPC: H01L21/20
Filed: 1986-07-31
Abstract: PURPOSE:To obtain a high-quality and homogeneous single crystal semiconductor thin film, by providing a stress applying section near a single crystal semiconductor region serving as a seed section so that the melting point near the seed section is decreased by a stress created by a difference in thermal expansion coefficient when irradiated with energy beams and the semiconductor in and near the seed section can be melted easily to allow recrystallization to proceed smoothly. CONSTITUTION:A polycrystalline silicon thin film 12 is formed on SiO2 layers 13 and seed sections 15 and is separated by side walls 20 of the SiO2 layers 13 into island regions. An LOCOS-type wafer 14 produced in this manner is provided with stress applying sections 16 having a thickness of 0.5 mum on the portions of the polycrystalline silicon thin film islands 12 corresponding to the seed sections 15. Said stress applying sections 16 are formed of a material having a thermal expansion coefficient different from that of silicon. For example, it is formed of SiO2. When the wafer is irradiated with linear electronic beams, stress is concentrated at the ends 18 because of a difference in thermal expansion coefficient between SiO2 and silicon and the melting point of the ends 18 is decreased. Accordingly, the seed section 15 and the polycrystalline silicon thin film islands 12 can be melted more easily by that decrease of the melting point and, therefore, recrystallization is allowed to proceed smoothly.
