Reconstituted wafer stack packaging with after-applied pad extensions
摘要：
A stacked microelectronic unit is provided which can include a plurality of vertically stacked microelectronic elements (12, 12A) each having a front surface (117), contacts (22) exposed at the front surface, a rear surface (118) and edges (18, 20) extending between the front and rear surfaces. Traces (24) connected with the contacts may extend along the front surfaces towards edges of the microelectronic elements with the rear surface of at least one of the stacked microelectronic elements being adjacent to a top face (90) of the microelectronic unit. A plurality of conductors (66) may extend along edges of the microelectronic elements from the traces (24) to the top face (90). The conductors may be conductively connected with unit contacts (76) such that the unit contacts overlie the rear surface (118) of the at least one microelectronic element (12A) adjacent to the top face.
摘要（中）：

提供堆叠的微电子单元，其可以包括多个垂直堆叠的微电子元件（12,12A），每个微电子元件具有前表面（117），在前表面暴露的触点（22），后表面（118）和边缘（18 ，20）在前表面和后表面之间延伸。 与触点连接的轨迹（24）可以沿着前表面朝着微电子元件的边缘延伸，其中至少一个堆叠的微电子元件的后表面与微电子单元的顶面（90）相邻。 多个导体（66）可以沿着微电子元件的边缘从迹线（24）延伸到顶面（90）。 导体可以与单元触点（76）导电连接，使得单元触点覆盖邻近顶面的至少一个微电子元件（12A）的后表面（118）。
