| ELS-F100 Ultra High Precision Electron Beam Lithography System | |
 |
Superior 100kV Lithography System The beam current range is significantly expanded from 20pA to 100nA. The electron optics is so designed that the beam diameter remains uniform within the maximum 1mm writing field. Throughput is surprisingly improved for wide-area nanoscale patterning |
Key Product Features
Ultra Fine Line Lithography |
|
|
ELS-F100 produces a highly stable beam with a diameter down to 1.8nm. This allows fine pattern to be drawn with a line width of 6nm or less. Over 40years of developing lithography systems have made it possible to realize high precision beams, long-term stability and high throughput all the same time. |
|
Ultra High Beam Position Accuracy with Laser Interferometer Stage |
|
|
The outstanding beam position resolution of 0.1nm is made possible using 20-bit DAC. A laser interferometer with an optical resolution of 0.3nm is included to achieve a stitching precision of +/-10nm and an overlay precision of +/-15nm in a 100um field. |
|
High-throughput Ultra-fine Processing System |
|
The beam current range from 20pA to 100nA and the new electron optics to keep the beam diameter small at high current in addition to the improved deflection system significantly improve throughput for wide area patterning. |
|
|
A Wide Variety of Lithography Software |
|
The application includes writing functions for graphics elements as a standard feature. In addtion, with the optional circle pattern generator, circles and arcs can be produced. Furthermore, by using the variable field size function, even WDM diffraction gratings can be produced. |
