摘要: A method for manufacturing a semiconductor device, a first structure is formed on a first substrate. A first bonded body is formed by bonding a supporting substrate lower in rigidity than the first substrate to a first principal surface, on which the first structure is formed, of the first substrate. The first substrate is removed from the first bonded body. A second structure is formed on a second substrate. A third structure is formed on a third substrate. A second bonded body is formed by bonding a second principal surface, on which the second structure is formed, of the second substrate to a third principal surface, on which the third structure is formed, of the third substrate. The second substrate is removed from the second bonded body. A third bonded body is formed by bonding a fourth principal surface, which is exposed after the first substrate is removed, of the first bonded body to a fifth principal surface, which is exposed after the second substrate is removed, of the second bonded body. The supporting substrate is removed from the third bonded body.

摘要: A method of producing graphene or other two-dimensional material such as graphene including heating the substrate held within a reaction chamber to a temperature that is within a decomposition range of a precursor, and that allows two-dimensional crystalline material formation from a species released from the decomposed precursor; establishing a steep temperature gradient (preferably >1000° C. per meter) that extends away from the substrate surface towards an inlet for the precursor; and introducing precursor through the relatively cool inlet and across the temperature gradient towards the substrate surface. The steep temperature gradient ensures that the precursor remains substantially cool until it is proximate the substrate surface thus minimizing decomposition or other reaction of the precursor before it is proximate the substrate surface. The separation between the precursor inlet and the substrate is less than 100 mm.

摘要: Energy bands of a thin film containing molecular clusters are tuned by controlling the size and the charge of the clusters during thin film deposition. Using atomic layer deposition, an ionic cluster film is formed in the gate region of a nanometer-scale transistor to adjust the threshold voltage, and a neutral cluster film is formed in the source and drain regions to adjust contact resistance. A work function semiconductor material such as a silver bromide or a lanthanum oxide is deposited so as to include clusters of different sizes such as dimers, trimers, and tetramers, formed from isolated monomers. A type of Atomic Layer Deposition system is used to deposit on semiconductor wafers molecular clusters to form thin film junctions having selected energy gaps. A beam of ions contains different ionic clusters which are then selected for deposition by passing the beam through a filter in which different apertures select clusters based on size and orientation.

摘要: A method for forming a heteroepitaxial layer includes forming an epitaxial grown layer on a monocrystalline substrate and patterning the epitaxial grown layer to form fins. The fins are converted to porous fins. A surface of the porous fins is treated to make the surface suitable for epitaxial growth. Lattice mismatch is compensated for between an epitaxially grown monocrystalline layer grown on the surface and the monocrystalline substrate by relaxing the epitaxially grown monocrystalline layer using the porous fins to form a relaxed heteroepitaxial interface with the monocrystalline substrate.

A gate stack including a gate electrode layer and a gate dielectric layer extending in a second direction perpendicular to the first direction is formed over the channel layer covering a portion of the length of the fin structure. The source and drain contacts are formed over trenches that extend into a portion of a height of the fin structure.
