    摘要: Semiconductor devices and methods for making semiconductor devices. The present invention allows a flip chip assembly to be used with an optical semiconductor device. The optical semiconductor flip chip is positioned over a hole in a PCB such that the imaging area of the optical semiconductor flip chip faces the hole. The hole allows the imaging area to be unobstructed by the PCB. Underfill material can be prevented from going into the hole by erecting a barrier on top of the PCB that surrounds the hole.

    摘要: In one aspect of the invention, a lead frame panel suitable for use in packaging an array of integrated circuits is described. The lead frame panel includes a matrix of tie bars that extend in substantially perpendicular rows and columns to define a two dimensional array of immediately adjacent device areas separated only by the tie bars. Each device area is suitable for use in an independent integrated circuit package and includes a die attach pad and a plurality of conductive contacts. In another aspect of the invention, a panel assembly suitable for use in simultaneously packaging a multiplicity of integrated circuits is described. The panel assembly includes a lead frame panel formed from a conductive sheet. The lead frame panel is patterned to define at least one two dimensional array of adjacent device areas. Each device area is suitable for use as part of an independent integrated circuit package and including a die and a plurality of contacts positioned around and electrically connected to the die. A molded cap is also provided that substantially uniformly covers a two dimensional array of adjacent device areas while leaving bottom surfaces of the conductive contacts exposed to facilitate electrical connection to external components. The encapsulation material that forms the molded cap is exposed at a bottom surface of the panel of integrated circuits to physically isolate the contacts.

    摘要: An improved wafer based packaging arrangement for integrated circuits is disclosed. In one aspect of the invention, external contacts are formed for the packaged integrated circuits by contact studs formed from bonding wires. One end of each contact studs is ball bonded to an associated wafer bond pad. An elongated portion of each wire (contact stud) extends outward the wafer surface and terminates at a second end that forms an external contact. Filling material surrounds a significant portion of the contact studs to hold the studs in place but leaves at least a portion of the second ends exposed to form external contacts. In some embodiments, the external contacts are substantially coplanar with the surface of the filling material, while in others, a protrusion beyond the filling material surface is left to form a contact bump. The wafers are eventually diced to form discrete packaged integrated circuits having external contacts formed by the contact studs.
