Abstract:
A microelectronic package has a dielectric element with first and second parallel apertures. A first microelectronic element has contacts overlying the first aperture, and a second microelectronic element has contacts overlying the second aperture. The second microelectronic element can overlie a rear face of the first microelectronic element and the same surface of the dielectric element as the first microelectronic element. First terminals on a second surface of the dielectric element between said first and second apertures can be configured to carry all data signals for read and write access to memory locations within the first and second microelectronic elements.
Abstract:
A chip package has multiple chips (22, 42)that may be arranged side by side or in a staggered, stair step arrangement. The contacts (36, 56) of the chips are connected to interconnect pads (60) carried on the chips themselves or on a redistribution interposer (402). The interconnect pads desirably are arranged in a relatively narrow interconnect zone (62), such that the interconnect pads can be readily wire bonded or otherwise connected to a package substrate.
Abstract:
A microelectronic package (100) can include a substrate (102) and a microelectronic element (130) having a face (134) and one or more columns (138, 139) of contacts (132) exposed thereat which face and are joined to corresponding contacts exposed at a surface (120) of the substrate. An axial plane (140) may intersect the face along a line in a first direction (142) and centered relative to the columns of element contacts (132). Columns (104A, 104B) of package terminals can extend in the first direction. First terminals exposed at a central region (112) of the second surface can be configured to carry address information usable to determine an addressable memory location within the microelectronic element. The central region (112) may have a width (152) not more than three and one-half times a minimum pitch (150) between the columns of package terminals. The axial plane can intersect the central region.

The terminals can include first terminals 104 arranged at positions within first and second sets 114, 124 thereof disposed on respective opposite sides of a theoretical axis 132. Each set of first terminals 104 can be configured to carry address information usable by circuitry within the package 100 to determine an addressable memory location in the memory storage array. The signal assignments of the first terminals 104 in the first set 114 can be a mirror image of the signal assignments of the first terminals in the second set 124.

A patterned bonding layer is disposed on a face of each of the first and second laminated microelectronic elements. The patterned bonding layers are mechanically and electrically bonded to form the microelectronic assembly.
Abstract:
An electrically conductive lead (137) is formed using a bonding tool (104). After bonding the wire (115) to a metal surface (112) and extending a length of the wire beyond the bonding tool, the wire is clamped. Movement of the bonding tool imparts a kink (116) to the wire at a location where the wire is fully separated from any metal element other than the bonding tool. A forming element (334), e.g., an edge or a blade skirt provided at an exterior surface of the bonding tool can help kink the wire. Optionally, twisting the wire while tensioning the wire using the bonding tool can cause the wire to break and define an end (138). The lead then extends from the metal surface (112) to the end (138), and may exhibits a sign of the torsional force applied thereto.
