Abstract: A chemical vapor deposition (CVD) apparatus is provided. The CVD apparatus comprises a deposition chamber and a main chamber. The deposition chamber comprises at least one single injector and one or more exhaust channels. The main chamber supports the deposition chamber and includes at least one gas inlet to inject at least one gas into the main chamber. The gases are removed through the exhaust channels, thereby creating an inwardly flowing purge which acts to isolate the deposition chamber. At least one semi-seal is formed between the deposition chamber and the substrate which acts to confine reactive chemicals within each deposition region.

Abstract: An injector and deposition chamber for delivering gases to a substrate or wafer for processing of said substrate or wafer is provided. The injector is provided comprising an elongated member with end surfaces and at least one gas delivery surface extending along the length of the member and which includes a number of first elongated passages formed therein for received a gas. The gas delivery surface contains rounded side regions and a center recessed region. Also formed within the member are a number of thin distribution channels which extend between the first elongated passages and the center recessed region of the gas delivery surface. In another embodiment, the injector further includes at least one second elongated passage formed therein for receiving an etchant species. The etchant species is conveyed via at least one thin distribution channel which extends between the second elongated passage and one of the rounded side regions of the gas delivery surface.

Abstract: A single body injector for delivering gases to a surface is provided. The injector is comprised of an elongated member with end surfaces and at least one gas delivery surface extending along the length of the member and which includes a number of elongated passages formed therein. Also formed within the member are a number of thin distribution channels which extend between the elongated passages and the gas delivery surface. In another embodiment of the invention a number of metering tubes may be inserted into each elongated passage and are spaced from the walls of the passages and extend between the ends. Gases are conveyed to the elongated passages, through the distribution channels to the gas delivery surface where they are directed to a desired region where they mix, react and form a uniform thin film on the substrate positioned beneath the injector.

Abstract: A gated electron-emitter is fabricated by a process in which particles (26) are deposited over an insulating layer (24). Gate material is provided over the insulating layer in the space between the particles after which the particles and any overlying material are removed. The remaining gate material forms a gate layer (28A or 48A) through which gate openings (30 or 50) extend at the locations of the removed particles. When the gate material deposition is performed so that part of the gate material extends into the spaces below the particles, the gate openings are beveled. The insulating layer is etched through the gate openings to form dielectric openings (32 or 52). Electron-emissive elements (36A or 56A) are formed in the dielectric openings. This typically involves introducing emitter material through the gate openings into the dielectric openings and using a lift-off layer (34), or an electrochemical technique, to remove excess emitter material.

Abstract: A method and apparatus for accurately characterizing the electron density and distribution of a confined plasma on the basis of high-frequency, broadband electromagnetic measurements is disclosed herein. The technique involves noninvasive, broadband measurement of electromagnetic transmission through a plasma. In one implementation, multivariate analysis techniques are employed to correlate features of the resultant spectra with plasma characteristics such as electron density or electron distribution. Alternately, such techniques are used to correlate the resultant spectra with parameters relating to conditions under which the plasma is generated. More specifically, the quantitative plasma characterization technique involves generating a set of broadband calibration spectra by measuring transmission of electromagnetic energy through a calibration plasma. Each broadband calibration spectrum is obtained using a different set of reference parameters being related to predefined quantitative characteristics.

Abstract: A method for depositing silicon dioxide on the surface of a substrate or the like using a nitrogen-containing precursor is disclosed herein. In a preferred implementation the deposition is performed using an atmospheric pressure reactor, into which is directed toward the substrate surface a stream of source gas comprised of ozonated oxygen. A stream of a nitrogen-containing precursor such as, for example, hexamethyldisilazane (HMDS) is also directed into the reactor toward the substrate surface. In addition, a stream of a nitrogen-containing separator gas is directed into the reactor between the streams of precursor and source gases. The inventive deposition method has been shown to result in improved film nucleation on a variety of substrate surfaces.
