Patent ID: 7572649

Claim:
A device transferring method for bonding a plurality of devices bonded to a first substrate to an adhesive layer formed on a second substrate, comprising the steps of: approaching said plurality of devices bonded to said first substrate to approach said adhesive layer formed on said second substrate; regulating the position of said first substrate to make said first substrate parallel to said second substrate while keeping at least a part of said plurality of devices bonded to said first substrate in contact with said adhesive layer formed on said second substrate, thereby to bring all of said plurality of devices into contact with said adhesive layer; bonding said plurality of devices bonded to said first substrate to said adhesive layer formed on said second substrate in the condition where said devices are in contact with said adhesive layer, for bonding to said second substrate said plurality of devices bonded to said first substrate, wherein said method is carried out by using a device transferring system which includes: a first substrate support portion on which to mount said first substrate; a second substrate support portion for supporting said second substrate disposed oppositely to said first substrate; a swinging unit for regulating the position of said first substrate so that said devices bonded to said first substrate make contact with the second substrate side in parallel to said second substrate side; a movable stage for supporting and moving said swinging portion; a sensor unit for sensing the condition where said devices bonded to said first substrate have made contact with said second substrate side, said sensor portion provided between said first substrate support portion and a sensor support portion formed on said swinging unit side; and a measuring unit for measuring the position of stop of a motion of said first substrate when said first substrate is made to approach said second substrate, and for measuring the moving amount of said swinging unit after said first substrate is stopped.
