    摘要: A cartridge-like chemical sensor is formed by a housing having a base and a cover fixed to the base and provided with an input opening, an output hole and a channel for a gas to be analyzed. The channel extends in the cover between the input opening and the output hole and faces a printed circuit board carrying an integrated circuit having a sensitive region open toward the channel and of a material capable to bind with target chemicals in the gas to be analyzed. A fan is arranged in the housing, downstream of the integrated device, for sucking the gas after being analyzed, and is part of a thermal control system for the integrated circuit.

    摘要: A method of forming buried cavities in a wafer of monocrystalline semiconductor material with at least one cavity formed in a substrate of monocrystalline semiconductor material by timed TMAH etching silicon; covering the cavity with a material inhibiting epitaxial growth; and growing a monocrystalline epitaxial layer above the substrate and the cavities. Thereby, the cavity is completely surrounded by monocrystalline material. Starting from this wafer, it is possible to form a thin membrane. The original wafer must have a plurality of elongate cavities or channels, parallel and adjacent to one another. Trenches are then excavated in the epitaxial layer as far as the channels, and the dividers between the channels are removed by timed TMAH etching.

    摘要: A process manufactures a wafer using semiconductor processing techniques. A bonding layer is formed on a top surface of a first wafer; a deep trench is dug in a substrate of semiconductor material belonging to a second wafer. A top layer of semiconductor material is formed on top of the substrate so as to close the deep trench at the top and form at least one buried cavity. The top layer of the second wafer is bonded to the first wafer through the bonding layer. The two wafers are subjected to a thermal treatment that causes bonding of at least one portion of the top layer to the first wafer and widening of the buried cavity. In this way, the portion of the top layer bonded to the first wafer is separated from the rest of the second wafer, to form a composite wafer.

    摘要: For manufacturing an SOI substrate, the following steps are carried out: providing a wafer of semiconductor material; forming, inside the wafer, a plurality of passages forming a labyrinthine cavity and laterally delimiting a plurality of pillars of semiconductor material; and oxidizing the pillars of semiconductor material to form a buried insulating layer. For forming the labyrinthine cavity, a trench is first formed in a substrate; an epitaxial layer is grown, which closes the trench at the top; the wafer is annealed so as to deform the pillars and cause them to assume a minimum-energy handlebar-like shape, and a peripheral portion of the wafer is removed to reach the labyrinthine cavity, and side inlet openings are formed in the labyrinthine cavity. Oxidation is performed by feeding an oxidizing fluid through the side inlet openings.

    摘要: A process for manufacturing a SOI wafer with buried oxide regions without cusps that includes forming, in a wafer of monocrystalline semiconductor material, trenches extending between, and delimiting laterally, protruding regions; forming masking regions, implanted with nitrogen ions, the masking regions surrounding completely the tips of the protruding regions; and forming retarding regions on the bottom of the trenches, wherein nitrogen is implanted at a lower dose than the masking regions. A thermal oxidation is then carried out and starts at the bottom portion of the protruding regions and then proceeds downwards; thereby, a continuous region of buried oxide is formed and is overlaid by non-oxidized regions corresponding to the tips of the protruding regions and forming nucleus regions for a subsequent epitaxial growth. The masking regions and the retarding regions are formed through two successive implants, including an angle implant, wherein the protruding regions shield the bottom portions of the adjacent protruding regions, as well as the bottom of the trenches, and a vertical implant is made perpendicularly to the wafer.
