BONDING APPARATUS AND METHOD FOR USING THE SAME
A bonding apparatus for bonding a driving circuit to a display panel includes: a bonding stage unit on which the display panel is supported in bonding the driving circuit to the display panel; a head unit located above the bonding stage unit and with which ultrasonic waves are applied to the driving circuit to couple the driving circuit with a bonding area of the display panel supported on the bonding stage unit; and a protrusion disposed at an edge portion of the bonding stage unit, the edge portion corresponding to an end of the display panel at which the bonding area is disposed.
TCB bond tip design to mitigate top die warpage and solder stretching issue
A semiconductor tool and methods of forming semiconductor device assemblies. The semiconductor tool is a bond tip having a vacuum port and a plurality of purge ports with channels coupling the vacuum port with the purge ports. Air may be withdrawn through the vacuum to create a vacuum on the bottom of the bond tip to selectively couple a semiconductor device with the bond tip. The bond tip positions the semiconductor device on top of a stack of semiconductor devices to form a semiconductor device assembly. The assembly may be heated to reflow interconnects between the semiconductor device and the top device of the stack of semiconductor devices. Fluid provided through the purge ports may help to counter warpage of the semiconductor device to help form adequate interconnects between the devices. Fluid may also be provided through the vacuum port to counter the warpage.

SEMICONDUCTOR MANUFACTURING APPARATUS AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
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.
Apparatus for direct transfer of semiconductor device die
A semiconductor device die transfer apparatus includes a first frame to hold a wafer tape having a plurality of semiconductor device die disposed on a side of the wafer tape and a second frame to secure a product substrate having a circuit trace thereon. The second frame is configured to secure the product substrate such that the circuit trace is disposed facing the plurality of semiconductor device die on the wafer tape. Additionally, a rotary transfer collet is disposed between the wafer tape and the product substrate. The rotary transfer collet has a rotational axis allowing rotation from a first position facing the wafer tape to pick a die of the plurality of semiconductor device die to a second position facing the circuit trace on the product substrate to release the die, thereby applying the die directly on the product substrate during a transfer operation.
