摘要:
A programmable material consolidation system includes a platen and an object release element on the platen. The object release element includes a lower surface configured to be secured to the platen and readily removed from the platen. An adhesive coating, which may cover at least a portion of the lower surface, may be formed from a material, such as a radiation-curable polymer, that is tacky when in an uncured state and not as tacky when in a substantially cured state. A nonstick coating on the platen may facilitate ready removal of the object release element therefrom. An upper surface of the object release element may include a material to which an object will adhere, but which may be readily removed from the object once fabrication thereof is complete.
摘要:
A programmed material consolidation method includes use of an object release element for facilitate removal of an object from a platen of programmed material consolation equipment while leaving substantially no residue on the platen or a fabricated object, and without requiring substantial post-release modification of the fabricated object. The object release element may be adhesively secured to a non-stick surface of the platen, with a material that adheres to the platen before being cured and that may be removed from the platen upon curing, or by application of a negative pressure through the platen to the object release element. The object release element may be formed from a material or include coating of a material, such as polyethylene, polyethyleneteraphthalate, or polyethylene ethyl ketone, that adheres to a fabricated object, but may be readily released from the fabricated object (e.g., by peeling).

A semiconductor component includes a thinned semiconductor die having protective polymer layers on up to six surfaces. The component also includes contact bumps on the die embedded in a circuit side polymer layer, and terminal contacts on the contact bumps in a dense area array. A method for fabricating the component includes the steps of providing a substrate containing multiple dice, forming trenches on the substrate proximate to peripheral edges of the dice, and depositing a polymer material into the trenches. In addition, the method includes the steps of planarizing the back side of the substrate to contact the polymer filled trenches, and cutting through the polymer trenches to singulate the components from the substrate. Prior to the singulating step the components can be tested and burned-in while they remain on the substrate.
摘要:
A method for testing a semiconductor component includes the steps of bonding an interconnect to the component to form bonded electrical connections, applying test signals through the bonded electrical connections, and then separating the interconnect from the component. The bonding step can be performed using metallurgical bonding, and the separating step can be performed using solder-wettable and solder non-wettable metal layers on the interconnect or the component. During the separating step the solder-wettable layers are dissolved, reducing adhesion of the bonded electrical connections, and permitting separation of the component and interconnect. The interconnect includes interconnect contacts configured for bonding to, and then separation from component contacts on the components. A system includes the interconnect, an alignment system for aligning the substrate to the interconnect, a bonding system for bonding the component to the interconnect, and a heating system for heating the component and the interconnect for separation.

A solder jet apparatus and method is disclosed. The solder jet apparatus is a continuous mode solder jet that includes a blanking system and raster scan system. The use of the raster scan and blanking systems allows for a continuous stream of solder to be placed anywhere on the surface in any desired X-Y plane. This allows for greater accuracy as well as greater product throughput. Additionally, with the raster scan system, repairs to existing soldered surfaces can be quickly and easily performed using a map of the defects for directing the solder to the defects.

A method for fabricating semiconductor components and interconnects includes the steps of providing a substrate, such as a semiconductor die, forming external contacts on opposing sides of the substrate by laser drilling vias through the substrate, and forming conductive members in the vias. The conductive members include enlarged terminal portions that are covered with a non-oxidizing metal. The method can be used to fabricate stackable semiconductor packages having integrated circuits in electrical communication with the external contacts. The method can also be used to fabricate interconnects for electrically engaging packages, dice and wafers for testing or for constructing electronic assemblies.
摘要:
A through-wafer interconnect for imager, memory and other integrated circuit applications is disclosed, thereby eliminating the need for wire bonding, making devices incorporating such interconnects stackable and enabling wafer level packaging for imager devices. Further, a smaller and more reliable die package is achieved and circuit parasitics (e.g., L and R) are reduced due to the reduced signal path lengths.

A semiconductor device package includes a die, a package encapsulating at least a portion of the die, and a plurality of leads. Each lead of the plurality includes an external portion. The external portion of each lead is substantially planar and extends outward from a bottom edge of the package. The external portion of each lead may be oriented in a plane that is substantially parallel to a plane within which the die is located. A semiconductor device including these features may be part of an assembly that also includes an alignment device for orienting the semiconductor device package in nonparallel relation to a substrate.
