摘要: Semiconductor chip packages and methods of fabricating the same. The package includes a thermally conductive protective structure having an indentation open to a front side and a flange surface at least partially surrounding the indentation and facing to the front of the structure. A chip is disposed in the indentation so that the front surface of the chip, with contacts thereon, faces toward the front of the structure. A flexible dielectric film having terminals thereon is placed on the flange surface, and a compliant material is disposed between the film and the flange surface. The terminals on the film are connected to the contacts on the chip. The individual terminals on the film are movable with respect to the protective structure, which facilitates mounting and compensation for thermal expansion.

摘要: A method of packaging a semiconductor chip assembly includes the encapsulation of the same after establishing an encapsulation area and providing a physical barrier for protecting the terminals of a chip carrier. An alternative or supplement to providing a physical barrier is to provide a preform of an encapsulation material which includes a predetermined volume of such material so that only the encapsulation area is filled. For a semiconductor chip assembly which does not yet have an elastomeric layer, a method of simultaneously forming such an elastomeric layer and encapsulating a semiconductor chip assembly is also provided.

摘要: Microelectronic assemblies such as semiconductor chip assemblies are encapsulated. During encapsulation, the terminals carried by a dielectric layer in each assembly, and the bottom surface of the semiconductor chip in each assembly are protected by covering layers. The covering layers confine the liquid encapsulant and prevent contamination of the terminals and chip bottom surfaces. The encapsulation process may be conducted by using a tilting fixture. The liquid encapsulant and the assemblies are placed into the fixture, the fixture is closed and evacuated, and the encapsulant is then poured onto the assemblies while maintaining the fixture under vacuum. The fixture is then pressurized and maintained under pressure during cure of the encapsulant.

摘要: A component for mounting semiconductor chips or other microelectronic units includes a flexible top sheet with an array of terminals on it, and with flexible leads extending downwardly from the terminals. A compliant dielectric support layer surrounds the leads, holding the lead tips in precise locations. The leads are desirably formed from wire such as gold wire, and have eutectic bonding alloy on their tips. The component can be laminated to a chip or other unit under heat and pressure to form a complete subassembly with no need for individual bonding to the contacts of the chip. The subassembly can be tested readily and provides compensation for thermal expansion.

摘要: Microelectronic contacts, such as flexible, tab-like, cantilever contacts, are provided with asperities disposed in a regular pattern. Each asperity has a sharp feature at its tip remote from the surface of the contact. As mating microelectronic elements are engaged with the contacts, a wiping action causes the sharp features of the asperities to scrape the mating element, so as to provide effective electrical interconnection and, optionally, effective metallurgical bonding between the contact and the mating element upon activation of a bonding material.
