Proforma 300SA Semi-Automated Wafer Characterization System from MTI Instruments

The Proforma 300SA is a semi-automated thickness measurement system for both semiconducting and semi-insulating wafer materials. Capable of handling 200 mm and 300mm wafers, the 300SA provides highly accurate, repeatable measurements of thickness, TTV, bow, warp, site and global flatness.

Built around MTI Instruments' exclusive Push-Pull capacitance technology, the Proforma 300SA delivers full wafer surface scanning at the press of a button. User defined and ASTM/SEMI scan patterns are used to generate a full 3-dimensional image of the wafer.

Easy to Use....

The standard Windows® user interface makes the Proforma 300SA easy to use and set-up. Each measurement and machine parameter is selectable from a list of standard options. The control software has three levels of security, from a production environment to a full engineering analysis of wafer geometry. Customized data reports, as well as the ability to export measurement data to any spreadsheet add the ability to match the Proforma 300SA to your process needs
