The die separation assembly includes a support base having a support surface. A feed tray includes a collection end positioned adjacent the base such that an elongated, substantially tin gap is formed between the tray collection end and at least a portion of the base. A flexible platform is movably supported atop the base support surface for movement along the base. Upon movement of the flexible platform down the down-ramped portion of the support base, a portion of the wafer saw tape thereat is peeled away from the respective die. The tape is the separated from the dice, releasing the respective dice onto the collection end of the feed tray in a manner substantially maintaining their forward alignment orientation of thereof.

摘要： A method of forming an interconnection contact for integrated circuit package components includes providing an integrated circuit package component having a contact pad on which the interconnecting contact is to be formed. The interconnecting contact is formed by forming at least a portion of a bonding wire loop connected to the contact pad. A first end of a bonding wire is connected to the contact pad. The bonding wire loop includes a wire portion extending outwardly from the contact pad. The portion of the bonding wire loop forms the interconnection contact for electrically connecting the integrated circuit package component to other electrical devices. In one embodiment, a second end of the bonding wire loop is connected to the same contact pad that the first end of the bonding wire loop is connected to. In another embodiment, a second end of the bonding wire loop is connected to another contact pad. The integrated circuit package component may be an integrated circuit die or an interconnecting device such as an interconnecting substrate for interconnecting other integrated circuit package components or for connecting the integrated circuit package to other electrical elements. An encapsulating material may be used to encapsulate the particular surface of the integrated circuit package component, the contact pad, and portions of the bonding wire loop.

摘要： An apparatus and method for forming a layer of underfill adhesive on an integrated circuit in wafer form is described. In one embodiment, the layer of underfill adhesive is disposed and partially cured on the active surface of the wafer. Once the underfill adhesive has partially cured, the wafer is singulated. The individual integrated circuits or die are then mounted onto a substrate such as a printed circuit board. When the solder balls of the integrated circuit are reflowed to form joints with corresponding contact pads on the substrate, the underfill adhesive reflows and is completely cured. In an alternative embodiment, the underfill adhesive is fully cured after it is disposed onto the active surface of the wafer.

摘要： Flip chips with improved solder bump strength are provided. A solder mask layer is placed and patterned on a front side of a wafer of semiconductor chips with semiconductor devices and bond pads. The solder mask is patterned to expose the bond pads. Solder bumps are electrically connected to the bond pads. The solder mask is thick enough to extend up to at least a quarter of the solder bumps and is in contact with the solder bumps. The wafer is then cut into individual chips. The chips may be sold to customers, who may mount the chip on a substrate without underfill.

摘要： A method and an apparatus for forming a plastic chip on chip module is disclosed. The plastic chip on chip module is formed by placing a stacked chip set into a molding chamber suitably arranged to receive encapsulant. The stacked chip set includes a daughter chip that is electrically and mechanically coupled to a mother chip where the daughter chip is directly aligned to and separated from the mother chip by a standoff gap. Encapsulant is then passed into the molding chamber filling the standoff gap substantially simultaneously with surrounding the chip set to form the plastic chip on chip module.

摘要： Provided herein are optical sensor devices, methods for making the same, and systems including the same. An optical sensor device, according to an embodiment, includes a light detector die and a light source die attached to the same or different die attachment substrates so that there is a space between the light source die and the light detector die. A light transmissive material covers the light detector die, the light source die and at least a portion of the space between the light detector die and the light source die. A groove is formed (e.g., saw, blade or laser cut, or cast) in the light transmissive material between the light detector die and the light source die, and an opaque material is put within the groove to provide a light barrier between the light detector die and the light source die.

摘要： A power converter can include an output circuit having a high-side device and a low-side device which can be formed on a single die (a “PowerDie”). The power converter can further include a controller integrated circuit (IC) formed on a different die which can be electrically coupled to, and co-packaged with, the PowerDie. The PowerDie can be attached to a die pad of a leadframe, and the controller IC die can be attached to an active surface of the first die such that the first die is interposed between the controller IC die and the die pad.
