    摘要: An electron beam exposure system for producing a desired pattern on a workpiece. The pattern is specified by predetermined pattern data. The pattern data is modified with correction data. The correction data is obtained from information indicating variations on the level of the surface of the workpiece due to an elastic deformation thereof during the exposure process. With the use of the correction data, the desired pattern is correctly reproduced as intended when the workpiece is fully supported and the surface thereof recovers its flatness.

    摘要: A coreless seal 11 for being assembled in a shell-type roller bearing provided in a shell-type roller bearing comprises an elastic annular member 12. An outer diameter B of the coreless seal 11 for being assembled in the shell-type roller bearing is a dimension provided by adding interference 2A for an amount of thermal shrinkage to an inner diameter C of a shell-type outer ring. Since the annular member 12 shrinks in a direction shown by an arrow W at low temperature, the outer diameter of the coreless seal 11 for being assembled in the shell-type roller bearing is reduced from B to B′. However, since the outer diameter B is provided with the dimension A obtained by adding interference for an amount of thermal shrinkage, the coreless seal 11 for being assembled in the shell-type roller bearing has interference A′ in its outer diameter B′ even after the shrinkage.

    摘要: The present invention relates to a method of manufacturing a semiconductor device including a step of exposing a resist by use of an exposure mask. An object of the present invention is to facilitate a level adjustment of the reticle and thus automatically determine an optimum focus. The present invention has steps of providing a reticle with a plurality of inspection patterns, which are positioned within a dicing line area around a semiconductor integrated circuit forming area on the reticle, and of which each has a size such that their transferred patterns are changed in shape according to an amount of deviation in focus, and exposing a resist by use of the reticle.

    摘要: A reticle and a method of fabricating the same for projecting a fine pattern on an object surface comprises: a transparent substrate; a first type phase-shifter selectively patterned and deposited on the substrate producing a phase difference between the light passing therethrough and the light passing through the other areas without phase-shifter; and a second type phase-shifter selectively patterned and forming a groove in the substrate producing a phase difference between the light passing therethrough and the light passing through the other areas without phase-shifter. The reticle may include a patterned shield layer which interrupts transmission of light, and the phase difference of the first and second type phase-shifters is many times selected substantially equal to a half wavelength of light. Another type of a reticle comprises: a transparent substrate; a phase-shifter of a first groove; and another phase-shifter of a second deeper groove formed in the first groove.

    摘要: A machine with vibration source includes a frame for carrying a vibration source such as a motor. A housing is attached to a bottom of the frame, in which a sphere made of a rigid material is housed rotation free in a manner that a portion of the sphere is projected from an opening at the bottom of the housing. The surface of a plate made of a rigid material contacts the portion of the sphere projecting from the housing and the plate is surrounded by a member of an elastic material. The elastic member has an upwardly extending portion which surrounds the housing, and therefore, the elastic member controls the relative position between the sphere and the plate, and resultingly, rolling of the machine can be suppressed. In addition, since the sphere can be rotated on the plate, horizontal vibration of the machine is absorbed to be suppressed. Furthermore, since the sphere is supported by the plate and the plate is supported by a floor via the elastic member, vertical vibration of the machine is also suppressed.
