  • Patent number: 8129229
    Abstract: A metal leadframe to be used in manufacturing a “flip-chip” type semiconductor package is treated to form a metal plated layer in an area to be contacted by a solder ball or bump on the chip. The leadframe is then process further to form an oxide or organometallic layer around the metal plated layer. Pretreating the leadframe in this manner prevents the solder from spreading out during reflow and maintains a good standoff distance between the chip and leadframe. During the molding process, the standoff between the chip and leadframe allows the molding compound to flow freely, preventing voids in the finished package.

  • Patent number: 8129231
    Abstract: A semiconductor package can comprise a die stack attached to a substrate, with bond wires electrically connecting the two. Often multiple die stacks are adhered to a single substrate so that several semiconductor packages can be manufactured at once. A molding compound flow controller is optimally associated with the substrate or semiconductor package at one or more various locations. Flow controllers can control or direct the flow of the molding compound during the encapsulation process. Flow controllers can be sized, shaped, and positioned in order to smooth out the flow of the molding compound, such that the speed of the flow is substantially equivalent over areas of the substrate containing dies and over areas of the substrate without dies. In this manner, defects such as voids in the encapsulation, wire sweeping, and wire shorts can be substantially avoided during encapsulation.

  • Patent number: 8129243
    Abstract: Methods of forming non-volatile memory cell structures are described that facilitate the use of band-gap engineered gate stacks with asymmetric tunnel barriers in reverse and normal mode floating node memory cells that allow for direct tunnel programming and erase, while maintaining high charge blocking barriers and deep carrier trapping sites for good charge retention. The low voltage direct tunneling program and erase capability reduces damage to the gate stack and the crystal lattice from high energy carriers, reducing write fatigue and enhancing device lifespan. The low voltage direct tunnel program and erase capability also enables size reduction through low voltage design and further device feature scaling. Such memory cells also allow multiple bit storage. These characteristics allow such memory cells to operate within the definition of a universal memory, capable of replacing both DRAM and ROM in a system.

  • Patent number: 8129248
    Abstract: In the method of producing bipolar transistor structures in a semiconductor process, an advanced epitaxial trisilane process can be used without the risk of poly stringers being formed. A base window is structured in a polycrystalline silicon layer covered with an oxide layer, and a further step is epitaxial growing of a silicon layer in the base window from trisilane. The window structuring is performed in a sequence of anisotropic etch and isotropic ash steps, thereby creating stepped and inwardly sloping window edges. Due to the inwardly sloping side walls of the window, the epitaxially grown silicon layer is formed without inwardly overhanging structures, and the cause of poly stringers forming is thus eliminated.

  • Patent number: 8129262
    Abstract: Fabrication of an insulated-gate field-effect transistor (110) entails separately introducing three body-material dopants, typically through an opening in a mask, into body material (50) of a semiconductor body so as to reach respective maximum dopant concentrations at three different vertical locations in the body material. A gate electrode (74) is subsequently defined after which a pair of source/drain zones (60 and 62), each having a main portion (60M or 80M) and a more lightly doped lateral extension (60E or 62E), are formed in the semiconductor body. An anneal is performed during or subsequent to introduction of semiconductor dopant that defines the source/drain zones. The body material is typically provided with at least one more heavily doped halo pocket portion (100 and 102) along the source/drain zones. The vertical dopant profile resulting from the body-material dopants alleviates punchthrough and reduces current leakage.

  • Patent number: 8129269
    Abstract: In a BEOL process, UV radiation is used in a curing process of ultra low-k (ULK) dielectrics. This radiation penetrates through the ULK material and reaches the cap film underneath it. The interaction between the UV light and the film leads to a change the properties of the cap film. Of particular concern is the change in the stress state of the cap from compressive to tensile stress. This leads to a weaker dielectric-cap interface and mechanical failure of the ULK film. A layer of nanoparticles is inserted between the cap and the ULK film. The nanoparticles absorb the UV light before it can damage the cap film, thus maintaining the mechanical integrity of the ULK dielectric.

  • Patent number: 8129270
    Abstract: Top-down methods of increasing reflectivity of tungsten films to form films having high reflectivity, low resistivity and low roughness are provided. The methods involve bulk deposition of tungsten followed by a removing a top portion of the deposited tungsten. In particular embodiments, removing a top portion of the deposited tungsten involve exposing it to a fluorine-containing plasma. The methods produce low resistivity tungsten bulk layers having lower roughness and higher reflectivity. The smooth and highly reflective tungsten layers are easier to photopattern than conventional low resistivity tungsten films. Applications include forming tungsten bit lines.
