摘要:
A structure and method for achieving a flip-chip semiconductor device having plated copper inductors (4), transformers (16), interconnect, and power busing that is electrically superior, lower cost, and provides for higher quality inductors as well as lower losses for on-chip transformers. Providing a solder dam (8, 24, 28) enables the fabrication of flip-chip solder bumps directly on to inductors and transformers.
摘要:
An optoelectric interconnect (70) includes an optical fiber (17) coupled to a ferrule (11) and an optoelectric board (20). Metal layer (14) is disposed over a surface (12) of the ferrule (11). An optoelectric device (61) is coupled to the optoelectric board (20) using tape automated bonding tapes (47, 51). The optoelectric board (20) and the ferrule (11) are positioned adjacent each-other so that optical radiation is transmitted from the optoelectric device (61) to the optical fiber (17). The position of the optoelectric device (61) is adjusted to achieve an optimum position which is characterized by a maximum optical radiation transmitted to the optical fiber(17). Upon achieving the optimum position, two bonding strips (54, 56) are fused with the metal layer (14) on the surface (12) of the ferrule (11).
摘要:
A method for encapsulating a surface of an integrated circuit to protect the surface. The surface has an outer peripheral area and an inner area to be encapsulated. A frame is provided for handling an integrated circuit package. A plurality of leads are coupled between the frame and the outer peripheral area. An encapsulation material is dispensed on the outer peripheral area covering and protecting a portion of the leads and integrated circuit. A planar encapsulation material is deposited for covering and protecting the inner area. The planar encapsulation material provides a planar surface.
