  • Simultaneous double side grinding of silicon wafers a

    A series of processes are required to manufacture high quality silicon wafers. Simultaneous double side grinding (SDSG) is one of the processes to flatten the wire-sawn wafers. This paper reviews the literature on SDSG of silicon wafers covering the history machine development (including machine configuration drive and support systems and Therefore a modern wafer grinding machine begins with a coarse grinding wheel to get a fast removal of the silicon and at the end follows a fine grinding process step with small grit size grinding wheel. This final process is absolute necessary when thinning down to 50 μm in order to minimize subsurface damage and stress.

    The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding Increasing the wafer diameter from φ300 mm to φ450 mm is required to enhance semiconductor devices productivity. A high-stiffness rotary grinding machine equipped with water hydrostatic bearings was developed for a φ450 mm silicon wafer. The grinding machine has an upper structure consisting of a wheel spindle system and a lower structure consisting of a rotary worktable system.

  • Wafer grinding ultra thin TAIKOdicing-grinding service

    Partial Wafer Grinding is an efficient grinding method to process broken or damaged wafers or wafer sections. This technique can be employed to process wafers that had been damaged or wafer sections that are still intact thereby avoiding loss of the entire wafer material. The silicon blocks (ingots) are cut into wafers using wire saws. Rollers guide the saw wires across a wire field where the distance between wires determines the thickness of the wafer. The saw wires are moved back and forth between an unwinder and a winder at a speed of > 20 m/s and kept at a constant tension by a dancer control.
