  The present invention is a component management for grasping a product in which a component causing a defect is assembled when a defect occurs in a product manufactured by a product manufacturer using a component supplied from a component supplier. About the system.

  In the semiconductor device manufacturing process, a plurality of regions are partitioned by dividing lines called streets arranged in a lattice pattern on the surface of a substantially wafer-shaped semiconductor wafer, and devices such as ICs, LSIs, etc. are partitioned in the partitioned regions. Form. Then, the semiconductor wafer is cut along the streets to divide the region in which the device is formed to manufacture individual devices. In addition, an optical device wafer in which a gallium nitride compound semiconductor or the like is laminated on the surface of a sapphire substrate or silicon carbide substrate is also divided into optical devices such as individual light emitting diodes and laser diodes by cutting along the streets. Widely used.

  A wafer such as the semiconductor wafer described above is formed to have a predetermined thickness by grinding the back surface with a grinding device before being divided into individual devices. A grinding apparatus for grinding a back surface of a semiconductor wafer includes a chuck table having a holding surface for sucking and holding the wafer, a grinding means including a grinding wheel for grinding the wafer sucked and held by the holding surface of the chuck table, and the grinding Grinding feed means for grinding and feeding the means in a direction perpendicular to the holding surface of the chuck table (see, for example, Patent Document 1).

  The cutting along the wafer street is usually performed by a cutting device called a dicer. This cutting apparatus includes a chuck table for holding a workpiece such as a semiconductor wafer or an optical device wafer, a cutting means for cutting the workpiece held on the chuck table, and a chuck table and the cutting means. And a cutting feed means for moving it.

  The above-described processing devices such as the grinding device and the cutting device are configured by a large number of parts, and many of these parts are supplied from the component supplier to the device manufacturer. Thus, the processing apparatus manufactured by assembling many parts in the apparatus manufacturer is delivered to the user and performs the above-described processing.

  As described above, when a failure occurs in the processing device delivered to the user, the device manufacturer investigates the cause and replaces the part that caused the failure to eliminate the failure. Further, when a defective part is mass-produced in the part manufacturing process, the apparatus manufacturer replaces the parts for all processing apparatuses in which the mass-produced defective part is used.
