Data Preparation

Data preparation means processing the data into a form suitable for further analysis, processing and mask making. This process involves many different tasks and cannot be fully automated. Many data preparation activities are routine, tedious and time-consuming. Therefore, it is essential to implement a robust and repeatable data preparation process quickly and efficiently.

This improves the productivity of template set creation and eliminates any risk of errors. Professional CAD staff of Alfa Chemistry provides tightly integrated data preparation services that automate the repetitive and time-consuming tasks between design and fracture.

About Alfa Chemistry's Data Preparation Service

Alfa Chemistry's photomask data preparation services include conversion and layout of customers' initial data according to specifications, as well as adding services, testing and other special elements.

In the photomask data preparation process, our professional CAD personnel check the initial information according to the data preparation rules, segment the data, apply a full-function correction system for optical proximity effect when necessary, and generate output information. In the final stage, the obtained data is converted into control information for the image generator.
