摘要： An electro-luminescent material and solid state electro-luminescent device comprising a mixed material layer formed of a mixture of silicon and silicon oxide doped with rare earth ions so as to show intense room-temperature photo- and electro-luminescence is described. The luminescence is due to internal transitions of the rare earth ions. The mixed material layer has an oxygen content ranging from 1 to 65 atomic % and is produced by vapor deposition and rare earth ions implant. A separated implant with elements of the V or III column of the periodic table of elements gives rise to a PN junction. The so obtained structure is then subjected to thermal treatment in the range 400.degree.-1100.degree. C.

The method comprises the steps of: chemically altering the surfaces of the silicon plates to have different functional groups provided in the undercut from those in the remainder of the surfaces; and selectively reacting the functional groups provided in the undercut with an organic molecule having a reversibly reducible center and a molecular length substantially equal to the width of the undercut, thereby to establish a covalent bond to each end of the organic molecule.

摘要： A method of controlling the quantity and uniformity of distribution of bonded oxygen atoms at the interface between the polysilicon and the monocrystalline silicon includes carrying out, after having loaded the wafer inside the heated chamber of the reactor and evacuated the chamber of the LPCVD reactor under nitrogen atmosphere, a treatment of the wafer with hydrogen at a temperature generally between 500 and 1200° C. and at a vacuum generally between 0.1 Pa and 60000 Pa. The treatment is performed at a time generally between 0.1 and 120 minutes, to remove any and all the oxygen that may have combined with the silicon on the surface of the monocrystalline silicon during the loading inside the heated chamber of the reactor even if it is done under a nitrogen flux. After such a hydrogen treatment, another treatment is carried out substantially under the same vacuum conditions and at a temperature generally between 700 and 1000° C. with nitrogen protoxide (N2O) for a time generally between 0.1 and 120 minutes.

摘要： A MOS-gated power device integrated structure comprises a plurality of elementary units formed in a semiconductor material layer of a first conductivity type. Each elementary unit is formed in a body stripe of a second conductivity type. There are a plurality of body stripes of the second conductivity type extending substantially in parallel to each other and at least one source region of the first conductivity type disposed within each body stripe. A conductive gate layer is insulatively disposed over the semiconductor material layer between the body stripes in the form of a first web structure. A second web structure of the second conductivity type is formed in the semiconductor material layer and comprises an annular frame portion surrounding the plurality of bodystripes and at least one first elongated stripe extending between two sides of the annular frame portion in a direction substantially orthogonal to the body stripes and that is merged at each end with the annular frame portion. The body stripes are divided by the at least one first elongated stripe into at least two groups of body stripes, wherein one end of each body stripe is merged with the annular frame portion of the second conductivity type and the other end is merged with the at least one first elongated stripe. A conductive gate finger is insulatively disposed above the first elongated stripe and is part of the first web structure. A conductive gate ring surrounds the conductive gate layer and the conductive gate finger and completes the first web structure. A metal gate finger is disposed above the conductive gate finger and is merged at its ends with a metal gate ring structure disposed above the conductive gate ring to provide a third web structure. Source metal plates cover the at least two groups of body stripes and contact each source region and each body stripe to form a source electrode of the power device. A bottom surface of the semiconductor material layer forms a drain of the power device.
