    摘要: Process for the production of an oriented monocrystalline silicon film with localized defects on an insulating support.This process consists of covering a monocrystalline silicon support of orientation (100) with a SiO.sub.2 layer, producing in the latter a configuration having in the form of oriented (100) parallel insulating strips, an alternation of overhanging parts and recessed parts carrying out the etching of the SiO.sub.2 layer in order to locally form at the ends of said layer at least one opening, said etching being continued until the substrate is exposed, depositing on the etched SiO.sub.2 layer a silicon film, covering the silicon film with an encapsulating layer, carrying out a heat treatment of the structure obtained in order to recrystallize the silicon film in monocrystalline form with the same orientation as the substrate and eliminating the encapsulating layer.

    摘要: Processes are provided for fabricating a substrate having a silicon-on-insulator (SOI) or silicon-on-nothing (SON) architecture, which are applicable to the manufacture of semiconductor devices, especially transistors such as those of the MOS, CMOS, BICMOS, and HCMOS types. In the fabrication processes, a multilayer stack is grown on a substrate by non-selective full-wafer epitaxy. The multilayer stack includes a silicon layer on a Ge or SiGe layer. Active regions are defined and masked, and insulating pads are formed so as to be located around the perimeter of each of the active regions at predetermined intervals and placed against the sidewalls of the active regions. The insulating trenches are etched, and the SiGe or Ge layer is laterally etched so as to form an empty tunnel under the silicon layer. The trenches are filled with a dielectric. In the case of an SOI archiutecture, the tunnel is filled with a dielectric.

    摘要: A transistor including a germanium-rich channel. The germanium-rich channel is produced by oxidation of the silicon contained in the silicon-germanium intermediate layer starting from the lower surface of the said intermediate layer. The germanium atoms are therefore caused to migrate towards the upper surface of the silicon-germanium intermediate layer, and are stopped by the gate insulating layer. The migration of the atoms during the oxidation step is thus less prejudicial to the performance of the transistor, since the gate insulator of the transistor has already been produced and is not modified during this step. The migration of the germanium atoms towards the gate insulator, which is immobile, leads to a limitation of the surface defects between the channel and the insulator.

    摘要: A method for forming a single-crystal semiconductor layer portion above a hollowed area, including growing by selective epitaxy on an active single-crystal semiconductor region a sacrificial single-crystal semiconductor layer and a single-crystal semiconductor layer, and removing the sacrificial layer. The epitaxial growth is performed while the active region is surrounded with a raised insulating layer and the removal of the sacrificial single-crystal semiconductor layer is performed through an access resulting from an at least partial removal of the raised insulating layer.

    摘要: Silicon-based single-crystal portions are produced on a surface of a substrate, selectively in zones where a single-crystal material is initially exposed. To do this, a layer is firstly formed over the entire surface of the substrate, using a silicon precursor of the non-chlorinated hydride type, and under suitable conditions so that the layer is a single-crystal layer in the zones of the substrate where a single-crystal material is initially exposed and amorphous outside these zones. The amorphous portions of the layer are then selectively etched so that only the single-crystal portions of the layer remain on the substrate.
