    摘要: A method for joining a multiplicity of multi-alloy solder columns to an electronic substrate and the structure formed by such method are disclosed. In the method, a mold plate equipped with a multiplicity of cavities is first filled by an injection molded solder technique with a high temperature solder forming a multiplicity of solder columns. The mold plate is then sandwiched between an extraction plate and a transfer plate by utilizing a multiplicity of displacement means equipped in the extraction plate to displace the multiplicity of solder columns from the mold plate into a multiplicity of apertures equipped in the transfer plate. The multiplicity of cavities in the transfer plate each has a straight opening and a flared opening. The flared opening is then filled with a low temperature solder paste to encapsulate one end of the high temperature solder column. The low temperature solder paste is then reflown on top of a conductive pad on an electronic substrate at a temperature lower than the melting temperature of the high temperature solder to form a bond between the solder column and the conductive pad.

    摘要: A plurality of through-substrate holes is formed in each of at least one substrate. Each through-substrate hole extends from a top surface of the at least one substrate to the bottom surface of the at least one substrate. The at least one substrate is held by a stationary chuck or a rotating chuck. Vacuum suction is provided to a set of through-substrate holes among the plurality of through-substrate holes through a vacuum manifold attached to the bottom surface of the at least one substrate. An injection mold solder head located above the top surface of the at least one substrate injects a solder material into the set of through-substrate holes to form a plurality of through-substrate solders that extend from the top surface to the bottom surface of the at least one substrate. The vacuum suction prevents formation of air bubbles or incomplete filling in the plurality of through-substrate holes.

    摘要: A method of implementing an injection molded soldering process for three-dimensional structures, particularly, such as directed to three-dimensional semiconductor chip stacking. Also provide is an arrangement for implementing the injection molded soldering (IMS) process. Pursuant to an embodiment of the invention, the joining of the semiconductor chip layers with a substrate is implemented, rather than by means of currently known wire bond stacking, through the intermediary of columns of solder material formed by the IMS process, thereby providing electrical advantages imparted by the flip chip interconnect structures. In this connection, various diversely dimensioned solder column interconnects allow for simple and dependable connections to a substrate by a plurality of superimposed layers or stacked arrays of semiconductor components, such as semiconductor chips. In accordance with a further aspect, it is possible to derive a unique design for an IMS mold structure, which contains cavities for forming the columnar fill of solder, and which also incorporates further cavities acting as cutouts for dies or the positioning of other electronic packages or modules.
