Title: Contact fetching circuit
Inventor: FUKUI TOSHIKAME
IPC: H03K19/0175
Filed: 1979-04-16
Abstract: PURPOSE: To improve the reliability of a system by detecting whether a fetch signal from a positive logic insulating element and an inverted fetch signal from a negative logic insulating element are normal and then by outputting a fetch-signal abnormality signal when they are normal.  
     CONSTITUTION: Contact fetching power supply 2 is insulated from internal logic circuit power supply 8, and positive logic insulating element 10 transfers the on-off state of contact 1 as it is; and signal inverting circuit 5 converts the on-off state of contact 1 into an inverted signal and negative logic insulating element 11 transfers the on-off state of contact 1 inverted by circuit 5. Here, fetch signal abnormality detecting circuit 6 receives the fetch signal transferred from element 10 and the inverted fetch signal transferred from element 11 to check whether the fetch signal is normal and when it is no normal, a fetch-signal abnormality signal is output. Consequently, faults of the primary side of the insulating element are judged on the secondary side of the insulating element to make it possible to improve the reliability of the system.

Title: Evaluation of practical resolution of reduction projection exposure apparatus
Inventor: TAGUCHI TAKASHI
IPC: H01L21/027
Filed: 1989-02-28
Abstract: PURPOSE:To quantitatively evaluate a practical resolution correctely and without scattering by multiplying a practical resolution index LFE by an integration factor obtained by multiplying a mask factor by a spatial frequency. CONSTITUTION:A practical resolution index LFE is obtained. Then, when a dimension of line pattern on a mask is denoted by L, a dimension of a space is denoted by S and a dimensional difference between the mask and a formed resist pattern is denoted by  L, (L -  L)/L and 1000/(L+S) as a spatial frequency are calculated. Then, an integration factor obtained by multiplying the spatial frequency by a mask pattern fidelity factor is multiplied by an index LFE which has conventionally been used for evaluation of practical resolution to obtain a factor indicating a degree of integration, and practical resolution is evaluated thereby. According to this method, the fidelity of the target dimension to the mask pattern and the spatial frequency are also taken into consideration and the practical resolution can be quantitatively evaluated correctly without scattering of values.
