Schott-Lithotec

Key technologies for semiconductor production

Schott Lithotec, a 100% subsidiary of the Mainz technology corporation Schott, manufactures optical materials and components for microlithography. Schott Lithotec is unique in that it is the only company in the world to cover the whole spectrum of materials required.

Fascinating technology for measurements of millionths of a meter

Microlithography is the process currently used for the manufacture of electronic components. Masks created with UV lasers are mapped on silicium wafers, thus creating chip structures in nanometer sizes. The demands on the optical components of a mapping lens are enormous. The dimensions of the systems can be measured in meters, and yet they have to provide micrometer accuracy. The economic leverage power of microlithography is also enormous: world-wide, optical components costing US $ 0.8 billion are used to manufacture electronic components valuing US $ 1,000 billion.

Microscopically precise Quality Control

So it should come as no surprise that the focus of the DeltaMaster application for Schott Lithotec lies with the evaluation of quality data critical to business success. The application draws together quality and production process data from various sources, on the basis of which new key evaluation figures are continuously generated and checked for correlations.

Modeling and analysis as a closed loop

A closed loop procedure typifies the analysis processes: insights lead to the fine-tuning of the data model, then analysis of the fine-tuned model leads to new insights, which in turn lead to further fine-tuning and so on. DeltaMaster caters to this with its Closed Loop Principle, which allows for a high degree of modeling flexibility during analysis.


Closed Loops: New key figures in dialogs
without reprocessing the data pool

New measures in dialogs

With the help of dialogs, new key figures (measures) are displayed in the Frontend on the basis of values already present in the database. Numerous calculation templates help generate statistical figures (e.g. variation, median, mean, interquartile range, Gini coefficient). The application thus covers quotient generation, filter values, uni- and bivariate statistical measures and operations such as deviations and cumulations.

When even this spectrum of possibilities isn't enough, a supply of MDX commands is available in all dialogs.
