Title: Projection aligner and manufacture of device
Inventor: HIROSE TAKAMASA
IPC: G03F7/20
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To give a high optical characteristic to a projection alighner by reducing the adverse effect of unnecessary diffracted light emitted from a diffraction optical element on a screen by constituting the aligner so that the aligner may emit another diffracted light which has a different order from that of one diffracted light, is made incident to a substrate, and forms a uniform light intensity distribution in the substrate. SOLUTION: An aperture stop decides the pupil surface of a projection optical system PL and primary and secondary diffraction optical elements BOE1 and BOE2 formed on the surface of each lens are composed of binary optics elemtns. There two element BOE1 and BOE2 are formed in lenses faced oppositely to each with a pupil surface SP in between near the surface SP. Since the elements BOE1 and BOE2 are respectively arranged before and after the pupil surface SP of the optical system PL near the surface SP, various kinds of aberrations including the chromatic aberration are excellently corrected and, at the same time, the exposure unevenness on a screen which is caused by the adverse effect of a flare component composed of unnecessary diffracted light emitted from each element BOE1 and BOE2 on the screen is avoided.

Title: Semiconductor integrated circuit device
Inventor: SAITO YOSHIKAZU
IPC: H01L27/06
Filed: 1994-03-16
Abstract: PURPOSE:To prevent dielectric breakdown at the gate of an MOSFET effectively by providing a protective element between the gate terminal of the MOSFET constituting an internal circuit and a power supply voltage terminal or a drain terminal. CONSTITUTION:When a surge voltage lower than the ground potential is applied to an input pin 2 and a current flows from a ground pin 5 toward the input pin 2 through an input protective MOSFETQi, the potential at node N1 connected with an internal logic circuit 6 is dropped significantly by the parasitic resistance Rs of a feeder line Lg. Even if the internal logic circuit 6 output Low level and the output voltage therefrom drops significantly, a protective diode D1 connected with the input terminal of next stage internal logic circuit 7 is biased forward to feed a current. Consequently, an overvoltage is prevented from being applied to the gate-source or the gate-drain of MOSFETQ21, Q22 thus preventing dielectric breakdown at the gate.

Then, the signal of the level 1 is outputted to the line 24b, the relay 10 is turned on, the second number is outputted to the line 24c and then, the call instruction pulse is generated in the line 24d. At the time, when the line is busy again, the signal level of the line 24b is turned to zero, the relay 10 is turned off, the waiting is performed for one minute and an original state is returned. Thus, the need of restraining call until the line is free is eliminated even when the line is in use and a prompt communication processing can be performed.
