    Abstract: A support section (28) for supporting a wafer (1) is convexly formed in the center of a receiving section (26) of a support groove (25) of a boat 21. At the time of boat loading of the boat (21), in which wafers (1) respectively received by the supporting sections (28) are aligned, from a standby chamber (33) to a processing chamber (14), the pressure in the standby chamber (33) and processing chamber (14) is set to 200 pascals or more, and 3000 pascals or less. By supporting the wafer upwards from the receiving section with use of the support section, even if peeling of the film on the wafer occurs from a large frictional force between the supported surface of the wafer and the support section under a reduced pressure, the particles from the peeling are caught by the receiving section and therefore particles are prevented from adhering to the IC fabrication surface of the wafer directly below the receiving section.

    Abstract: A barrier layer including a titanium film is formed at a low temperature, and a TiSix film is self-conformably formed at the interface between the titanium film and the base. In forming the TiSix film 507, the following steps are repeated without introducing argon gas: a first step of introducing a titanium compound gas into the processing chamber to adsorb the titanium compound gas onto the silicon surface of a silicon substrate 502; a second step of stopping introduction of the titanium compound gas into the processing chamber and removing the titanium compound gas remaining in the processing chamber; and a third step of generating plasma in the processing chamber while introducing hydrogen gas into the processing chamber to reduce the titanium compound gas adsorbed on the silicon surface and react it with the silicon in the silicon surface to form the TiSix film 507.

    Abstract: A method can be used for the production of a coated substrate. The coating contains copper. A copper precursor and a substrate are provided. The copper precursor is a copper(I) complex which contains no fluorine. A copper-containing layer is deposited by means of atomic layer deposition (ALD) at least on partial regions of the substrate surface by using the precursor. Optionally, a reduction step is performed in which a reducing agent acts on the substrate obtained in the layer deposition step. In various embodiments, the precursor is a complex of the formula L2Cu(X?X) in which L are identical or different ?-donor-? acceptor ligands and/or identical or different ?,?-donor-? acceptor ligands and X?X is a bidentate ligand which is selected from the group consisting of ?-diketonates, ?-ketoiminates, ?-diiminates, amidinates, carboxylates and thiocarboxylates.

  • Patent number: 7842581
    Abstract: When a metal layer formed by reaction of a metal source and an oxygen (O2) source is deposited, oxidization of a conductive layer disposed under or on the metal layer can be reduced and/or prevented by a method of forming the metal layer and a method of fabricating a capacitor using the same. Between forming the conductive layer and the metal layer, and between forming the metal layer and the conductive layer, a cycle of supplying a metal source, purging, supplying an oxygen source, purging, plasma processing of reduction gas and purging is repeated at least once. In this case, the metal layer is formed by repeating a cycle of supplying a metal source, purging, supplying an oxygen source and purging.

  • Patent number: 7838353
    Abstract: Disclosed are embodiments of field effect transistors (FETs) having suppressed sub-threshold corner leakage, as a function of channel material band-edge modulation. Specifically, the FET channel region is formed with different materials at the edges as compared to the center. Different materials with different band structures and specific locations of those materials are selected in order to effectively raise the threshold voltage (Vt) at the edges of the channel region relative to the Vt at the center of the channel region and, thereby to suppress of sub-threshold corner leakage. Also disclosed are design structures for such FETs and method embodiments for forming such FETs.

  • Patent number: 7838379
    Abstract: In a phase change memory, electric property of a diode used as a selection device is extremely important. However, since crystal grain boundaries are present in the film of a diode using polysilicon, it involves a problem that the off leak property varies greatly making it difficult to prevent erroneous reading. For overcoming the problem, the present invention provides a method of controlling the temperature profile of an amorphous silicon in the laser annealing for crystallizing and activating the amorphous silicon thereby controlling the crystal grain boundaries. According to the invention, variation in the electric property of the diode can be decreased and the yield of the phase-change memory can be improved.
