    Abstract: A leadframe of a leadless flip-chip package includes a plurality of inner leads, a nonconductive ink layer and a solder mask layer. The inner leads have a plurality of bump-connecting terminals, a plurality of outer terminals and a plurality of redistribution lead portions. A half-etched recession is formed on lower surfaces of the redistribution lead portions, and is filled with the non-conductive ink layer. The non-conductive ink layer fixes the redistribution lead portions onto the bump-connecting terminals. The solder mask layer is easily formed on the non-conductive ink layer and covers the inner leads.

  • Publication number: 20080088029
    Abstract: A semiconductor device having a contact barrier for insulating contacts with a large aspect ratio and having a fine pitch between adjacent conductive lines and a method of manufacturing the same are provided. The semiconductor device includes a buried contact formed in a region between two adjacent first conductive lines and two adjacent second conductive lines. Insulating lines define a width of the buried contact. To form the contact barrier, an interlayer dielectric layer formed on the second conductive lines is patterned to form a space and an insulating line having an etching ratio different from the interlayer dielectric layer is formed in the space. The interlayer dielectric layer is selectively wet etched relative to an insulating layer covering the second conductive line and the first insulating line to form buried contact hole. The buried contact hole is filled with conductive material to form a buried contact.

    Abstract: A method of forming a metal line in a semiconductor device is disclosed. The method of forming a metal line in a semiconductor device includes forming an interlayer insulating film over a substrate. A via hole may be formed by selectively patterning the interlayer insulating film. A metal film may be formed over a surface of the interlayer insulating film including an inner portion of the via hole. The inner portion of the via hole may be filled with copper. A copper layer exposed over the surface of the interlayer insulating film may be deplated using reverse current to form a copper metal line and a recess region over the copper metal line. An upper insulating film may be formed over the surface of the interlayer insulating film including the recess region by deposition. An insulating cap layer may be selectively formed over only the recess region on the copper metal line by etching the upper insulating film.

  • Publication number: 20070269948
    Abstract: A two-bits-per-cell flash memory cell is based on a localized trapping storage mechanism. The memory cell may be programmed via a hot hole injection mechanism and erased via a Fowler-Nordheim electron tunneling mechanism. The memory cells are arranged according to a virtual-ground wiring scheme. Gate structures of the memory cells are arranged in columns, and the widths of the columns are essentially equal to the distance between the columns. Bit lines elongate in pairs between the columns of memory cells and connect corresponding impurity regions being associated to one of the columns of memory cells. Separation devices separating the bit lines of each pair of bit lines are formed symmetrically to the edges of the neighboring columns of memory cells. Program cross-talk issues, concerning memory cells sharing the same bit line, may be avoided while memory cell size remains essentially unaffected.

  • Publication number: 20070246830
    Abstract: An interconnect structure and method for manufacturing are described wherein an insulating material adjacent to or at least partially surrounding a conductive interconnect has a coefficient of thermal expansion (CTE) equal to or larger than the CTE of the interconnect. For example, a copper-based damascene interconnect layer may be provided, wherein an inter-layer dielectric (ILD) a least partially surrounds the interconnect layer and a cap insulator is disposed on the interconnect layer. In such an embodiment, the CTE of the ILD and/or the cap insulator would be at least as large as the CTE of the interconnect layer. This may result in no stress or compressive stress being applied by the insulating material to the interconnect layer when the device has cooled, such as to room temperature, after formation of the various layers.
