A component mounting system for mounting a component on a substrate, the mounting system comprising a component supplying unit configured to supply the component; a substrate holding unit configured to hold the substrate in an orientation such that a mounting face for mounting the component on the substrate is facing vertically downward; a head configured to hold the component from vertically below; and a head drive unit that, by causing vertically upward movement of the head holding the component, causes the head to approach the substrate holding unit to mount the component on the mounting face of the substrate.

A die attach system is provided. The die attach system includes a verification substrate configured to receive a plurality of die, the verification substrate including a plurality of substrate reference markers. The die attach system also includes an imaging system for determining an alignment of the plurality of die with the verification substrate by imaging each of the plurality of die with respective ones of the plurality of substrate reference markers.

A bonding device measures a position deviation amount of the chip with respect to the substrate in a state where the chip and the substrate are in contact, and corrects and moves the chip relatively to the substrate in such a way as to reduce the position deviation amount, based on the measured position deviation amount. Then, the bonding device fixes the chip to the substrate by irradiating a resin portion of the chip with an ultraviolet ray and curing the resin portion when the position deviation amount of the chip with respect to the substrate is equal to or less than a position deviation amount threshold value.

A method for transferring a plurality of die operatively associated with a transfer apparatus to a glass substrate to form a circuit component. The transfer occurs by positioning the glass substrate to face a first surface of a die carrier carrying multiple die. A reciprocating transfer member thrusts against a second surface of the die carrier to actuate the transfer member thereby causing a localized deflection of the die carrier in a direction of the surface of the glass substrate to position an initial die proximate to the glass substrate. The initial die transfers directly to a circuit trace on the glass substrate. At least one of the die carrier or the transfer member is then shifted such that the transfer member aligns with a subsequent die on the first surface of the die carrier. The acts of actuating, transferring, and shifting are repeated to effectuate a transfer of the multiple die onto the glass substrate.

A conveying unit for conveying a device chip onto a predetermined electrode of a board has a chip chuck that holds under suction one surface of the device chip, a support base to which the chip chuck is fixed in an inclinable manner, and a moving unit that moves the support base, in which a fixing mechanism that fixes the chip chuck to the support base has a plurality of leaf springs extending laterally radially from the chip chuck, the plurality of leaf springs are connected to the support base in the surroundings of the chip chuck, and the plurality of leaf springs are pulled one another, so that the chip chuck is supported in air in an inclinable manner.

A bonding tool and a bonding method are provided. The method includes attaching a semiconductor die to a bonding tool having a first surface, wherein the bonding tool comprises a bending member movably arranged in a trench of the bonding tool, and the bending member protrudes from the first surface and bends the semiconductor die; moving the semiconductor die toward a semiconductor wafer to cause a retraction of the bending member and a partial bonding at a portion of the semiconductor die and the semiconductor wafer; and causing a full bonding between the semiconductor die and the semiconductor wafer subsequent to the partial bonding.

A dipping apparatus includes a squeegee device and a plate for forming a flux film out of flux. A surface of the plate has a rough surface with a nano-level arithmetically average roughness. The dipping apparatus is configured in such a way that the squeegee device and the plate are moved relatively to each other, and the flux is fed from the squeegee device to the rough surface of the plate.

Provided are package-on-package (POP)-type semiconductor packages including a lower package having a first size and including a lower package substrate in which a lower semiconductor chip is, an upper redistribution structure on the lower package substrate and the lower semiconductor chip, and alignment marks. The packages may also include an upper package having a second size smaller than the first size and including an upper package substrate and an upper semiconductor chip. The upper package substrate may be mounted on the upper redistribution structure of the lower package and electrically connected to the lower package, and the upper semiconductor chip may be on the upper package substrate. The alignment marks may be used for identifying the upper package, and the alignment marks may be below and near outer boundaries of the upper package on the lower package.

A curable resin or adhesive composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and at least one energy converting material, preferably a phosphor, capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

Embodiments of the present disclosure include method for sequentially mounting multiple semiconductor devices onto a substrate having a composite metal structure on both the semiconductor devices and the substrate for improved process tolerance and reduced device distances without thermal interference. The mounting process causes “selective” intermixing between the metal layers on the devices and the substrate and increases the melting point of the resulting alloy materials.
