    摘要: A method of fabricating a semiconductor structure includes the steps of providing a semiconductor substrate having a material disposed thereon, masking the material with a mask having an appropriate pattern for forming a semiconductor structure, etching unmasked portions of the material so as to form the semiconductor structure, wherein the etching produces a film which attaches onto the semiconductor structure and/or on the semiconductor substrate, and removing the film from the semiconductor structure according to the steps of producing a cryogenic jet stream having cryogenic particles therein, and directing the cryogenic jet stream at the film such that the crogenic jet stream impinges on and causes the film to decrease in temperature so that a high temperature gradient develops between the film and the semiconductor structure, the film detaching from the semiconductor structure and fracturing due to contraction caused by the decrease in temperature and high temperature gradient.

    摘要: An aerosol cleaning apparatus for cleaning a substrate includes an aerosol producing means having a nozzle head. The nozzle head is positioned at a selected proximity and orientation to the substrate which is held by a rotatable holder. The aerosol spray dislodges particles from the substrate and the rotation of the substrate further assists in the removal of the loosened particles. A method of aerosol cleaning includes rotating a substrate at a preselected speed and spraying an aerosol jet in conjunction with the rotation to help in the removal of particles from the substrate.

    摘要: An apparatus for producing aerosol from a substance includes a heat exchanger for receiving and cooling a substance. The heat exchanger includes a housing; a cryogenic reservoir comprising a solid material mounted within the housing; temperature control means for controllably cooling the reservoir; and energy exchange means for allowing thermal contact between the reservoir and the substance for effectuating transfer of cooling energy from the cryogenic reservoir to the substance for controllably cooling the substance. A delivery line has an inlet for receiving the substance from the heat exchanger at a first pressure. A nozzle is connected to the delivery line for receiving the substance from the delivery line. The nozzle has at least one exit opening which allows passing of the substance therethrough for expanding the substance from the first pressure to a second pressure which is lower than the first pressure for solidifying the substance and producing aerosol. Condensation preventing means is provided for preventing condensation from forming on the delivery line and/or on the nozzle.

    摘要: A method of producing submicron nonagglomerated particles in a single stage reactor includes introducing a reactant or mixture of reactants at one end while varying the temperature along the reactor to initiate reactions at a low rate. As homogeneously small numbers of seed particles generated in the initial section of the reactor progress through the reactor, the reaction is gradually accelerated through programmed increases in temperature along the length of the reactor to promote particle growth by chemical vapor deposition while minimizing agglomerate formation by maintaining a sufficiently low number concentration of particles in the reactor such that coagulation is inhibited within the residence time of particles in the reactor. The maximum temperature and minimum residence time is defined by a combination of temperature and residence time that is necessary to bring the reaction to completion. In one embodiment, electronic grade silane and high purity nitrogen are introduced into the reactor and temperatures of approximately 770.degree. K. to 1550.degree. K. are employed. In another embodiment silane and ammonia are employed at temperatures from 750.degree. K. to 1800.degree. K.
