An assembly of a semiconductor chip having pads to a substrate having pads aligned to receive the semiconductor chip is provided, whereby at least one of the semiconductor chip pads and substrate pads include solder bumps. The solder bumps are deformed against the substrate pads and the semiconductor chip pads, whereby an underfill material is applied to fill the gap between the semiconductor chip and substrate. The underfill material does not penetrate between the deformed solder bumps, the semiconductor chip pads, and the substrate pads. At least one of the solder bumps have not been melted or reflowed to make a metallurgical bond between the semiconductor chip pads and the substrate pads, and at least another one of the solder bumps have been melted or reflowed to make a metallurgical bond between the semiconductor chip pads and the substrate pads.

A non-leaded semiconductor device comprises a sealing body for sealing a semiconductor chip, a tab in the interior of the sealing body, suspension leads for supporting the tab, leads having respective surfaces exposed to outer edge portions of a back surface of the sealing body, and wires connecting pads formed on the semiconductor chip and the leads. End portions of the suspension leads positioned in an outer periphery portion of the sealing body are unexposed to the back surface of the sealing body, but are covered with the sealing body. Stand-off portions of the suspending leads are not formed in resin molding. When cutting the suspending leads, corner portions of the back surface of the sealing body are supported by a flat portion of a holder portion in a cutting die having an area wider than a cutting allowance of the suspending leads, whereby chipping of the resin is prevented.

Provided is a flip chip bonder including: a pickup flipping collet configured to flip a chip; and a bonding tool configured to receive the chip flipped with the pickup flipping collet from the pickup flipping collet and to bond the received chip to a circuit board. The pickup flipping collet includes a cooling channel through which cooling air flows to cool the pickup flipping collet. Thus, bonding time can be reduced without lowering bonding quality.
