Abstract: When metal junction between a first electrode and a second electrode is executed as ultrasonic bonding between metals including at least copper, the ultrasonic bonding is performed in a state that a contact interface between the first electrode and the second electrode is covered with a bonding auxiliary agent. As a result, formation of oxide at a bonding interface between the first electrode and the second electrode due to execution of the ultrasonic bonding can be suppressed. Therefore, while a desired bonding strength is ensured, ultrasonic bonding with copper used for the first electrode or the second electrode can be fulfilled and cost cuts in mounting of semiconductor devices can be achieved.

Abstract: An electronic component placement machine and an electronic component placement method are disclosed. A takeout and transfer head, provided on rotary chip takeout and transfer mechanism, removes a chip from a feeder and flips it. A placement head receives the flipped chip and places it onto a board. An image of the chip at a pre-centering recognition position is captured during a takeout and transfer operation, during which the takeout and transfer head transfers the chip to the placement head at a receiving position, so as to recognize the position. Based on this positional recognition result, the chip and the placement head are positioned by controlling a placement head driving mechanism. Moreover, the takeout and transfer head is rotated to a position which does not hinder image capturing of the electronic component for placement positioning.
