The etch mask is removed and the entirety of the lower semiconductor layer within the exposed region is metallized. A first metal semiconductor alloy vertically abutting the insulator region is formed, while exposed surfaces of the stack of two heterogeneous semiconductor layers, which comprises the materials of the upper semiconductor layer, are concurrently metallized to form a second metal semiconductor alloy. An inflection point for current and, consequently, a region of flux divergence are formed at the boundary of the two metal semiconductor alloys.

    Abstract: A mounting substrate and a method of manufacturing the mounting substrate. The mounting substrate can include an insulation layer, a bonding pad buried in one side of the insulation layer in correspondence with a mounting position of a chip, and a circuit pattern electrically connected to the bonding pad. By utilizing certain embodiments of the invention, the process for stacking a solder resist layer can be omitted, as the bonding pads can be implemented in a form recessed from the surface of the insulation layer. In this way, the manufacturing process can be simplified and manufacturing costs can be reduced. Since the surface of the mounting-substrate on which to mount a chip can be kept flat without any protuberances, the occurrence of voids in the underfill can be minimized. This is correlated to obtaining a high degree of reliability, and leads to a greater likelihood of successful mounting.

  • Publication number: 20080200021
    Abstract: A multi-layered gate electrode stack structure of a field effect transistor device is formed on a silicon nano crystal seed layer on the gate dielectric. The small grain size of the silicon nano crystal layer allows for deposition of a uniform and continuous layer of poly-SiGe with a [Ge] of up to at least 70% using in situ rapid thermal chemical vapor deposition (RTCVD). An in-situ purge of the deposition chamber in a oxygen ambient at rapidly reduced temperatures results in a thin SiO2 or SixGeyOz interfacial layer of 3 to 4A thick. The thin SiO2 or SixGeyOz interfacial layer is sufficiently thin and discontinuous to offer little resistance to gate current flow yet has sufficient [O] to effectively block upward Ge diffusion during heat treatment to thereby allow silicidation of the subsequently deposited layer of cobalt. The gate electrode stack structure is used for both nFETs and pFETs.
