US Classification:
25049222, 700121, 430296, 430 30
Abstract:
The present invention relates to methods of predicting proximity heating of resists in electron beam lithography in real-time as the writing proceeds enabling beam compensation in current and/or dwell time to be performed during writing. A shifted impulse response function is shown to give proximity heating results accurate to within a few percent. A method of using a precomputed kernel capable of proximity resist temperature evaluation in real-time as beam writing proceeds.

Abstract:
The present invention relates to methods of predicting proximity heating of resists in electron beam lithography in real-time as the writing proceeds enabling beam compensation in current and/or dwell time to be performed during writing. A method of using a precomputed kernel capable of proximity resist temperature evaluation in real-time as beam writing proceeds by scalar product of the kernel with a graded cell size coverage map. A shifted impulse response function is shown to give the kernel values accurate to within a few percent.

US Classification:
347 19, 347 24, 358 19, 382167
Abstract:
Methods and apparatus for correcting defects, such as rounded corners and line end shortening, in patterns formed via lithography are provided. Such defects are compensated for “post-rasterization” by manipulating the grayscale values of pixel maps.

International Classification:
G09G 116
US Classification:
340747
Abstract:
A rasterizer, particularly suited for generating patterns for semiconductor masks and the like is described. An 8. times. 8 array uses RAS, CAS and WE signals in addition to the memory address for accessing the array. A state machine is used to convert the pattern data (e. g. , type of object orientation, etc. ) into accessing data with the WE generator being driven through a ROM.
Scanning Laser Lithography System Alignment Apparatus

Assignee:
ETEC Systems, Inc. - Beaverton OR
International Classification:
B41J 2435
US Classification:
346108
Abstract:
A direct-write lithography tool having improved alignment characteristics. The present invention discloses use of an optical alignment apparatus in a multi-beam lithography system. The optical alignment apparatus provides for alignment through a reduction lens utilized by the multi-beam lithography system for writing to semiconductor wafers and the like through use of optics for correction of distortion and curvature caused by viewing with a radiant energy beam of a different wavelength than the beams used for writing. Further, the alignment optics provide for multiple paths in a single optics system through use of liquid crystal retarders and beam splitters to direct the radiant energy beam through a selected optical path. In the present invention, a first optical path may provide for high magnification and a second for low magnification. Further, other optical paths may provide for bright or dark field illumination and viewing.
