摘要:
The present invention relates to a method for improving focusing in an electron column that generates an electron beam. The method for controlling the focusing of an electron beam in according to the present invention reduces the spot size of the electron beam when the electron beam reaches a specimen, so that resolution can be increased and the line width of a pattern in a semiconductor lithography process can be reduced, with the result that the performance of the electron can be improved.

In a non-conventional lap tool, i.e., not a stiff tool nor a conformable tool, and related method for grinding/polishing a substrate surface, includes a rigid base plate and attached work surface to define a cavity containing a non-Newtonian fluid. The non-Newtonian fluid behaves as a solid when the work surface is subjected to high shear stress, i.e., rapid tool stroke, yet behaves like a liquid when the tool is moved around the substrate surface when the shear stress of the work surface is low. A diaphragm can be used to further define the cavity and to seal within the non-Newtonian fluid therein.

Disclosed is an electrostatic quadrupole deflector for a microcolumn. The deflector includes an electron beam passage hole, deflecting electrodes to which a deflection voltage is applied, and floating electrodes to which the deflection voltage is not applied. The deflector is structurally stable and has a simple driving system. The deflector has good performance and characteristics.

摘要:
A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.

Disclosed herein is a multi-particle beam column including electrode layer with eccentric apertures. The multi-particle beam column includes two or more particle beam columns each comprising a particle beam emission source, a deflector, and two or more electrode layers. The multi-particle beam column includes at least one electrode layer having one or more apertures that are eccentric from respective beam optical axes of the particle beam columns.

A putter includes a handle (2), a putter head (1) with a striking surface, and two alignment indicia (6) symmetrically arranged relative to a vertical plane (20) which is perpendicular to the striking surface and passes through a striking line. Wherein the visible part of the alignment indicia (6) are symmetrical to the vertical plane (20) when being viewed in the vertical plane (20), while not symmetrical to the vertical plane (20) when being viewed in a plane offsetting from the vertical plane (20).
