Embodiments of various systems, methods, and devices for gang flipping and individual picking dies are disclosed. The embodiments disclosed herein may be used, for example, in the manufacture of directly bonded devices.

A flip-chip bonding method includes following operations. A wafer is provided with multiple semiconductor dies on an adhesive film held by a frame element. A semiconductor die is lifted up from the wafer by an ejector element. The semiconductor die is picked up with a collector element. The semiconductor die is flip-chipped with the collector element. An alignment check is performed to determine a position of the semiconductor die, so as to determine a process tolerance between a center of the collector element and a center of the semiconductor die. The semiconductor die with the collector element is transferred to a location underneath a bonder element based on the process tolerance of the alignment check. The semiconductor die is picked up from the collector element by the bonder element. The semiconductor die is bonded to a carrier by the bonder element.

A method includes configuring a bonding tool based on a first semiconductor die and a second semiconductor die, wherein the bonding tool includes a platform and a first bonding head and a second bonding head connected to the platform; attaching the first semiconductor die to the first bonding head; moving the first semiconductor die toward a semiconductor wafer to bond the first semiconductor die to the semiconductor wafer; releasing the first semiconductor die from the first bonding head; configuring the platform to cause the second bonding head to move the second semiconductor die to the location over the semiconductor wafer while keeping the first bonding head on the platform; and moving the second semiconductor die by the second bonding head toward the semiconductor wafer to bond the second semiconductor die to the semiconductor wafer.

When locating a semiconductor die on a substrate, the die is picked up and carried with a die-holding surface of a bonding tool having a protrusion. The protrusion of the bonding tool is configured to be movable between a retracted position within the die-holding surface and an extended position protruding from the die-holding surface. When the protrusion is located in the extended position, the die is bent when the bonding tool is carrying the die. Thereafter, the bonding tool is moved to flatten the die against the substrate while the substrate urges the protrusion to retract from the extended position towards the retracted position.

A method for bonding chips includes actuating a plurality of bonding heads to cause a plurality of chips to bond to a bonding surface supported by a carriage, and during the bonding of the plurality of chips to the bonding surface, actuating a plurality of force applicators to collectively impart a net moment of force to the carriage about a center of rotation of the carriage that opposes a net moment of force collectively imparted to the carriage about the center of rotation of the carriage by the plurality of bonding heads.

A method for bonding chips includes initially positioning a first bonding head at a first predetermined location relative to an initial position of a substrate chuck, wherein the first bonding head holds a first chip and wherein the substrate chuck supports a bonding surface, initially positioning a second bonding head at a second predetermined location relative to the initial position of the substrate chuck, wherein the second bonding head holds a second chip, alternating between receiving renewed position information of the substrate chuck and repositioning the first bonding head based on the received renewed position information until the first chip contacts the bonding surface, and alternating between receiving renewed position information of the substrate chuck and repositioning the second bonding head based on the received renewed position information until the second chip contacts the bonding surface, and bonding the first chip and the second chip to the bonding surface.
