    Abstract: A cleaning subsystem removes unwanted material, such as glaze, from saw blades used in a semiconductor singulation process. A cleaning module moves radially towards the saw blade and vertically with respect to the plane of the saw blade in order to enable abrasive cleaning blocks of the cleaning module to selectively remove material from either the upper and lower surfaces of the saw blade or the outer edge of the saw blade. The cleaning assembly can remove material from the saw blade at a predetermined time or position during the singulation process or upon detection of load imbalance during the rotation of the saw blade.

    Abstract: A main pole of a perpendicular magnetic recording write head is disclosed with a non-rectangular shape at the air bearing surface and a rectangular shape behind the air bearing surface. The main pole transitions from the non-rectangular shape to a rectangular shape at a distance of 10 nm to 100 nm behind the air bearing surface. The main pole includes leading and trailing beveled surfaces that extend from the non-rectangular shape of the pole at the air bearing surface toward the rectangular shape transition.

    Abstract: A semiconductor wafer has a multi-stage structure that damps and contains nascent cracks generated during dicing and inhibits moisture penetration into the active region of a die. The wafer includes an array of die regions separated by scribe lanes. The die regions include an active region and a first ring that surrounds the active region. A portion of the first ring includes a low-k dielectric material. A second ring includes a stack of alternating layers of metal and interlayer dielectric (ILD) material. A dummy metal region around the rings includes a stacked dummy metal features and surrounds the active region. A regular or irregular staggered arrangement of saw grid process control (SGPC) features reduces mechanical stress during dicing.
