Title: Electron beam lithography equipment and lithography process
Inventor: HAYATA YASUNARI
IPC: H01L21/027
Filed: 1990-09-14
Abstract: PURPOSE:To prevent deterioration in positional accuracy due to variable electromagnetic fields by providing a lithography equipment with an electron gun for measuring variable electromagnetic fields. CONSTITUTION:This invention is an electron beam lithography equipment comprising an electron gun 11 for measuring variable electromagnetic fields and an electron-position detector 13 in addition to a lithography electron gun 1: for example, the electron gun is a field emission type electron gun whose electron source is TiW. When electrons for measuring variable electromagnetic fields are kept detected by the detector 13, electromagnetic fields, if generated, other than those for deflection appear in the form of a positional deviation of an electron beam and can be sensed immediately. The intensity of electromagnetic fields can be estimated from the amount of positional deviation, and the distribution of intensity can be realized with a plurality of electron beams. Therefore, processing by estimation and correction of influences of these variable electromagnetic fields on lithography electron orbits allow high-accuracy electron beam lithography.

IPC: E01F13/04
Filed: 1994-09-12
Abstract: PURPOSE: To provide a bollard with a chain which can be mounted to any chains available at stores, and removed freely and enhanced in its outside view. CONSTITUTION: This device, which mounts a chain with a bollard, is designed to engage a ring 40 with a groove 33 in the radial direction of a fixing washer 30 in a state in which the end of a market available chain is inserted into the ring 40 and then penetrate a fixing screw 50 into a small through hole 32 and a large through hole and thread the screw 50 into the threaded part of a bollard 10, thereby enabling a chain 12 to be coupled with the bollard 10. Since the fixing screw 50 is buried in the fixing washer 30, it is impossible to remove the screw from the bollard 10 unless a tool is used, which is arranged to fit in a groove 53 formed on the head of the screw 50, if it is desired to remove the fixing screw 50 from the bollard 10. It is, therefore, impossible for any one except for the parties concerned to separate the chain 12 from the bollard 10.  In addition, the fixing screw 50 is buried in the fixing washer 30, which enhances the outside view more attractively.
