Title: Projection aligner
Inventor: KAWAKUBO SHOJI
IPC: H01L21/027
Filed: 1992-05-21
Abstract: PURPOSE:To obtain a projection aligner wherein its resolution is high, its depth of focus is large and its irradiation uniformity is excellent when an ordinary reticle which is used in the lithographic process of a semiconductor element is projected and aligned. CONSTITUTION:An irradiation light flux from a light source 1 is divided into four fluxes by using a first prism 20 to a third prism 22. The four light fluxes are incident on four sets of fly-eye lenses 40a to 40d, 41a to 41d whose centers are arranged in positions which are eccentric from the optical axis AX of an irradiation optical system. A main control system 50 moves the first to third prisms 20 to 22 individually to the direction of the optical axis by working in conjunction with a change in positions of the four sets of the fly-eye lenses 40a to 40d, 41a to 41d. The four light fluxes can be always made accurately incident on the individual corresponding fly-eye lenses 40a to 40d, 41a to 41d.

Title: Forming method of photo resist patterns
Inventor: OGATA TOSHIAKI
IPC: G03F7/095
Filed: 1977-10-26
Abstract: PURPOSE:To avoid excess hardening of pattern countour parts produced at the time of ion implantation and prevent the occurrence of peeling failure by peeling solution by forming photo resist patterns in an inverted truncated cone form in which the upper part is wider than the lower part. CONSTITUTION:A first layer 3 is formed by coating negative type photo resist on a substrate and subjecting the same to prebaking treatment. Next, a second layer 4 is formed in the similar manner by using negative type photo resist of a photo sensitivity higher than that of the photo resist of the first layer. Next, the photo resists are exposed through a glass mask 5 and are developed to leave the portions of 6, 7 respectively, whereby the patterns of inverted truncated cone form wherein the upper layer (second layer) is wider than the lower layer (first layer) are formed. If the patterns are formed in this way, the contour parts of the photo resists forming the patterns will not be subjected to radiation despite minor shrinkage in the upper part of the photo resists through ion implantation of a high concentration, thus excessive hardening may be avoidd. In the case of using positive type resist, the use of the photo resist of a lower photo sensitivity for the upper part gives equally good results.
