IPC: G03F7/20
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a projection aligner which can suppress fluctuations in high order spherical aberration when zonal illumination or modified illumination is carried out. SOLUTION: Apart from a light source unit 1 for light exposure, another light source unit 2 is provided for emitting illumination light IL2 having such wavelengths that will not be sensitive to photoresist on a wafer 13. Provided on an optical path of illumination light IL1 is a modified mirror 5 of mirrors 6A and 6B having reflecting surfaces tilted toward a reticle 10. The illumination light IL1 for light exposure from the light source unit 1 is passed through a zonal region around the modified mirror 5; while the illumination light IL2 for non-exposure is reflected by the reflecting surfaces of the modified mirror 5 to be directed toward the reticle 10 and a projection optical system 12. With the illumination light IL1 and IL2, a lens in the vicinity of a pupil surface of the projection optical system 12 can be illuminated with a uniform illumination distribution.

Title: Monitor display device
Inventor: ARAI CHIHARU
IPC: H04N3/227
Filed: 1987-09-04
Abstract: PURPOSE: To deal with a wide frequency by controllably moving the position of an image displayed on a cathode-ray tube(CRT) with each synchronizing signal before synchronous settlement, through a phase lag operation in a delay circuit for rough adjustment and fine adjustment provided on the input level for each horizontal and vertical synchronizing signal. CONSTITUTION: A horizontal and vertical oscillation signals outputted from an internal oscillation circuit 18d are forcedly synchronized with the frequency and the phase of a horizontal and vertical synchronizing signals e, f inputted from outside by each synchronous circuit 18, 24. In addition, the moving in the left and right and up-and-down directions of an image displayed on a CRT 20 display screen is such that the phase of the horizontal and vertical synchronizing signals e, f inputted from outside, before being synchronized in each synchronous circuit 18, 24, is advanced using a first delay circuit 16, 22 and a second delay circuit 17, 23. Consequently, no phase is moved of each synchronizing signal e, f after the settlement of synchronization; therefore, no synchronization of each oscillation signal deviates due to a phase movement adjusting operation.  Thus, the display device is capable of dealing with a wide frequency.
