Filed: 1990-07-23
Abstract: PURPOSE:To reduce the uneveness in light irradiation to a wafer and to carry out short time processing by providing plural turnable louvers on the whole area of a face to be irradiated with a lamp at a prescribed interval, between a material to be irradiated and the lamp. CONSTITUTION:The louvers 6 are provided between the material to be irradiate 5 and the lamp 2. In other words, when the material to be irradiated 5 is put in or taken out, the louvers 6 are all closed, and interrupt the irradiation light from the lamp 2. Therefore, irradiation is carried out only when needed for the material 5, so that the pre-processing of the material 5 can be carried out, and the short time processing can be carried out, as a whole. On the other hand, the louvers 6 are rocked during the irradiation of the lamp 2. Thus, the optical path of the irradiation of the lamp 2 is always changed, uneveness in illumination on the lamp 2 itself are hardly reflected on the material 5, and uniform irradiation can be carried out on the whole surface of the material 5.

Abstract: PURPOSE:To enable the automatic release even when a latch-up phenomenon appears by a method wherein a source and a drain of a MOS transistor and both ends of a resistor are connected between an internal power source wiring and a first power source terminal, and said internal power source wiring is connected to one of input terminals of a comparator and a second power source terminal is connected to another input terminal, and an output of the comparator is connected to said first power source terminal. CONSTITUTION:If some trigger is applied to an input terminal and an output terminal of a semiconductor integrated circuit element 1 and a latch-up phenomenon appears, a large quantity of current flows in the semiconductor integrated circuit element 1. As a result, a potential of an internal power source wiring 3 declines from a stationary state Va toward a GND level and when it becomes under (Va-alpha) at the time t2, an output of a comparator 6 becomes at a first power source voltage level and a P-channel type MOS transistor 4 becomes OFF. Accordingly, the potential of the internal power source wiring 3 approximately becomes the GND level and the latch-up state is released.
