摘要： Selected nonmagnetic semiconductor devices in an array of such devices are identified for subsequent processing by coating them with a material containing magnetizable particles. The devices are then tested to select those having the desired electrical characteristics. The selected devices in the array are contacted by the tip of a tubular marking stylus. A magnetic flux is concentrated at the tip and ink flows through stylus so that contact between the tip and article simultaneously magnetically and visibly marks the devices. Magnetic identification permits automatic sorting and removal of the selected devices from the array and the visible marking permits original set up of the array and subsequent verification of the sorting operation.
