    Fully automatic contact angle measuring instrument with wafer robot, loadport and SECS/GEM interface for 8" and 12" wafer technology. ...

  • Technical background

    Surface tension of photolithographic materials like resist and developer has a great potential for the photolithographic process itself. For instance, homogeneity of spin coatings, planarization, and adhesion depend directly on surface tension of the materials involved. The SURFTENS WH 300 contact angle meter serves for the measurement of contact angle and surface free energy (SFE) in semiconductor technology and provides the complete functionality, which is required in 300mm wafer fab´s. This makes the device unique worldwide.

  • SURFTENS HL
    SURFTENS HL 200 is a manually operated tool for contact angle measurement of Si-wafers. SURFTENS HL 200 meet the needs for a fast, highly accurate and comfortable measurement of the wettability of silicon wafers....

  • Background
    
    Surface tension of photolithographic materials like resist and developer has a great potential for the photolithographic process itself. 
    For instance, homogeneity of spin coatings, planarization, and adhesion depend directly on surface tension of the materials involved. 
    The same applys to the surface free energy (SFE) of coatings.
    Surface free energy (SFE) of substrates and layers, used in semiconductor technology can be investigated by contact angle measurement. 
    Measuring the contact angle allows you to quickly optimize new process steps as well as to better standardize known processes. 
    Small changes in the surface property of wafers are seen as large, easily detected changes in the contact angle. 
    A small investment of time to measure the contact angle, can give a large return by avoiding later production problems. 
    To reduce defect density and feature sizes of resist structures (<1μm), a good adhesion of the resist is necessary. 
    By the help of contact angle measurement, you can control the adhesion very easily.
    The contact angle measuring system SURFTENS HL 200 has been specially designed for use in the semiconductor industry and research, especially for process control in the surface treatment of Si wafers. 
    It is the ideal tool, to investigate contact angle and wettability of wafers. SURFTENS HL 200 meet the needs for a fast, highly accurate and comfortable measurement of the wettability of silicon wafers.
    The drop of test liquid (typically DI water) is produced by the manual or automatic direct dosing unit. The image of the drop appears immediately as a high quality, live video picture at the PC screen.  
    The Measurement is started by a single keystroke. The software determines the contact angle and immediately presents it graphically with numerical data included. Fast measuring times of only 1 second per drop exclude errors. 
    
    SURFTENS HL 200 guarantees highest reproducibility and measuring accuracy combined with ease of operation. 
    In the case of poor contrast images (can be caused by special coatings), a manual measuring function can be used.

    SURFTENS HL consisting of:
    -compact space-saving, closed mechanical basic setup
    --high quality measuring objective, fixed focus

  • COMEF
    Software for line width and CD measurement
    
    COMEF image processing software features the  easy and accurate measurement of line width, critical dimension (CD) and grid cycle. The COMEF measuring functions are based on grey value processing with subpixel accuracy. Beside the measuring functions, COMEF offers the comfortable documentation of the results in the digital image, in txt-files and in protocols.
    
    Camera interfaces and use with existing microscopes
    COMEF offers numerous interfaces to digital USB 2.0 cameras or any kind of analogue CCD-videocamera. 
    Therefore the software is perfect suited for upgrading existing microscopes.
    
    
    Measuring accuracy
    The accuracy is 1/10 of a camera pixel. 
    For practical use therefore the accuracy depends from the pixel size of the camera and the magnification of the optics between camera chip and object. 
    For a pixel size of 5 micron and a magnification of 10x the accuracy results to 50nm. Surely, the accuracy is limited by physical laws like diffraction and the dependence of the objective resolution from the numeral aperture of the measuring objective.
