Patent ID: 7193728

Claim:
A processing apparatus configured to process an electronic device, comprising: a plurality of light receiving units, among which a first light receiving unit is operable to receive light generated by a light emitting unit; a plurality of position detectors, among which a first position detector is operable to detect a position in terms of at least one coordinate of said electronic device based on said light received by said first light receiving unit; a processing unit operable to process said electronic device based on said position in terms of at least one coordinate of said electronic device detected by said first position detector; a device holding unit operable to hold said electronic device; a moving unit operable to move said electronic device; an adjusting unit operable to move said device holding unit to adjust said position of said electronic device with respect to said processing unit according to the position detected by the first position detector so that said electronic device can be disposed in a predetermined position, wherein said electronic device comprises a semiconductor device integrally formed with said light emitting unit, and wherein said processing unit processes said electronic device at a position that was adjusted by said adjusting unit, and wherein one of said plurality of position detectors detects said position of said electronic device based on light received by one of said plurality of light receiving units, and said moving unit moves said electronic device to a position in a vicinity of said processing unit based on said position of said electronic device detected by said one of said plurality of position detectors, and another one of said plurality of position detectors detects said position of said electronic device based on light received by another one of said plurality of light receiving units in a vicinity of said processing unit.
