Quantitation with the highest reliability is now made possible. This is ideal for quantitative analyses using internal standard methods for environmental, food, and other analyses. The automation of complicated sample preparation enabes quantitation with the highest reliability Two method files are provided to facilitate sample preparation: one for automatic addition of internal standard, and the other for automatic creation of calibration curve samples. Improvement in error contribution In comparison to previous systems the initial results from the VB show a marked improvement in the noise related error contribution. For Research Use Only. This design strategy has helped to eliminate the noise-induced errors seen on previous systems.

Enhancess Enhancess

In designing the new Enhancess Enhancess, Raith identified that a reduction of noise-induced positional errors would significantly improve tool performance. Leica Microsystems Lithography Ltd based in Cambridge, UK introduced their first vector-beam lithography tool in Since its introduction the various versions of the machine have been employed in a diverse range of applications including nanotechnology, micromechanics, micro optics, NGL maskmaking, si-direct write and telecommunications.

The Enhancess Enhancess tool provides the ability to load and expose piece parts as small as 5 mm through to full mm wafers with corresponding mask plate substrate sizes.

To achieve the stated specification the VB tool includes performance improvements in a number of key areas: height stability between the column and the sample, column electronics, and yaw and roll performance of the complete system.

Improving noise induced errors In Enhancess Enhancess to these improvements Raith wanted to improve noise induced errors and in particular to remove a peak mode at ~ Hz that was attributed to the interferometer configuration and mounting arrangement. Having worked successfully with Renishaw on a previous project involving RGH optical encoders, Raith selected the RLE20 fibre optic launched laser interferometer based encoder system for integration within the Enhancess Enhancess tool.

The differential interferometer configuration means that any mechanical perturbations of the mounting system are seen by both the reference and metrology beams i. The only issue then is the stability of the reference mirror, which has been designed to have high intrinsic stiffness and correspondingly high modes of vibration.

Electronic applications

This design strategy has helped to eliminate the noise-induced errors seen on previous systems. Luckily for us we were made aware of the development program at a time that enabled us to influence final design, ensuring its compatibility with our requirements. To provide the high resolution required by the VB tool, these signals are interpolated by Renishaw's RPI20 parallel interface to provide a least significant bit LSB resolution of Improvement in error contribution In comparison to previous systems the initial results from the VB show a marked improvement in the noise related error contribution.

This technique is used as it provides a measurement of the total noise in the system; mechanical and electrical, both on the beam and on the video system monitoring the back scattered electrons. Comparing the VB spectra to that taken from the VB6 tool it can be seen that the VB shows no evidence of the peak at Hz, the identified feature that Raith wanted to remove.

Additionally the peak at Hz had been removed and the Hz feature reduced.
