According to one embodiment, in a semiconductor manufacturing apparatus, a controller relatively moves a bonding tool and a stage close to each other while causing a semiconductor chip to adhere by suction to a surface via a tape using at least a first suction structure in a first period. In a second period, the controller controls the temperature of the bonding tool to a first target temperature while keeping substantially equal to a target pressure a pressure applied to the semiconductor chip by the bonding tool. In a third period, the controller controls a relative distance between the bonding tool and the stage so that the pressure applied to the semiconductor chip by the bonding tool is kept equal to the target pressure and controls the temperature of the bonding tool to a second target temperature. The second target temperature is higher than the first target temperature.

BONDING OF BRIDGE TO MULTIPLE SEMICONDUCTOR CHIPS

Interconnecting a first chip and a second chip by a bridge member includes a chip handler for handling the first chip and the second chip. Each of the first chip and the second chip has a first surface including a first set of terminals and a second surface opposite to the first surface. The chip handler has an opening and at least one support surface for supporting the first surfaces of the first chip and the second chip when the first chip and the second chip are mounted to the chip handler. A chip support member supports the first chip and the second chip from the second surfaces, and a bridge handler is provided for inserting the bridge member through the opening of the chip handler and for placing the bridge member onto the first sets of terminals of the first chip and the second chip.

PTFE sheet and method for mounting die

A PTFE sheet in which PTFE fibers having a diameter of 1 μm or less are spun, the PTFE sheet having a Gurley value in the range of 1 s/100 cc/in.sup.2 to 3 s/100 cc/in.sup.2 and a shrinkage factor in a direction orthogonal to a sheet winding direction of no more than 10% when heated to 300° C. The PTFE sheet makes a die adsorbable via a tool, which is for heating the die when the die is mounted on a mounting body, by being sandwiched between the die and the tool, and suppresses the adhesion, to an adsorption surface of the tool or to the die, of an adhesion member for fixing the die to the mounted body. Through this configuration, a PTFE sheet capable of stabilizing vacuum adsorption and improving maintainability and a method for mounting a die are provided.
