  • Patent number: 8962417
    Abstract: A semiconductor structure including a p-channel field effect transistor (pFET) device located on a surface of a silicon germanium (SiGe) channel is provided in which the junction profile of the source/drain region is abrupt. The abrupt source/drain junctions for pFET devices are provided by forming an N- or C-doped Si layer directly beneath a SiGe channel layer which is located above a Si substrate. A structure is provided in which the N- or C-doped Si layer (sandwiched between the SiGe channel layer and the Si substrate) has approximately the same diffusion rate for a p-type dopant as the overlying SiGe channel layer. Since the N- or C-doped Si layer and the overlying SiGe channel layer have substantially the same diffusivity for a p-type dopant and because the N- or C-doped Si layer retards diffusion of the p-type dopant into the underlying Si substrate, abrupt source/drain junctions can be formed.

  • Patent number: 8951922
    Abstract: The present invention relates to a method for fabricating an interlayer, and particularly relates to a method for fabricating an interlayer PCBM which is difficult to be dissolved in organic solvents. The solubility of the interlayer (PCBM) in organic solvents is decreased by polymerization of the interlayer (PCBM). Therefore, the thickness of the interlayer (PCBM) can be efficiently controlled, and the yield rate and efficiency of photoelectric devices can be improved.

    Abstract: In a high volume method for manufacturing a microelectronic package, a spacer element and a first die, i.e., microelectronic element, can be attached face-down to a surface of a substrate, contacts on the first die facing a first through opening of the substrate. Then, a second die can be attached face-down atop the first die and the spacer element, contacts on the second die disposed beyond an edge of the first die and facing a second through opening in the substrate. Electrical connections can then be formed between each of the first and second dies and the substrate. The first and second dies can be transferred from positions of a single diced wafer which are selected to maximize compound speed bin yield of the microelectronic package.

  • Patent number: 8933449
    Abstract: Apparatus having a dielectric containing scandium and gadolinium can provide a reliable structure with a high dielectric constant (high k). In an embodiment, a monolayer or partial monolayer sequence process, such as for example atomic layer deposition (ALD), can be used to form a dielectric containing gadolinium oxide and scandium oxide. In an embodiment, a dielectric structure can be formed by depositing gadolinium oxide by atomic layer deposition onto a substrate surface using precursor chemicals, followed by depositing scandium oxide onto the substrate using precursor chemicals, and repeating to form a thin laminate structure. A dielectric containing scandium and gadolinium may be used as gate insulator of a MOSFET, a capacitor dielectric in a DRAM, as tunnel gate insulators in flash memories, as a NROM dielectric, or as a dielectric in other electronic devices, because the high dielectric constant (high k) of the film provides the functionality of a much thinner silicon dioxide film.
