摘要:
An improved feeder system and method for continuous vapor transport deposition that includes at least two vaporizers couple to a common distributor through an improved seal for separately vaporizing and collecting at least any two vaporizable materials for deposition as a material layer on a substrate. Multiple vaporizer provide redundancy and allow for continuous deposition during vaporizer maintenance and repair.

This is to provide a film forming method, etc., which can form a film containing a high concentration of an impurity under atmospheric pressure efficiently without using a harmful and poisonous gas. The film forming method is constituted by heating a solid source such as boron and phosphorus pentaoxide, etc., and evaporating to generate a gas, and the obtained gas is jetted to the surface(s) of a preheated substrate to form a film.

PECVD apparatus for depositing material onto a moving substrate is provided comprising a process chamber, a precursor gas inlet to the process chamber, a pumped outlet, and a plasma source disposed within the process chamber. The plasma source produces one or more negative glow regions and one or more positive columns. At least one positive column is disposed toward the substrate. The plasma source and precursor gas inlet are disposed relative to each other and the substrate such that the precursor gas is injected into the positive column adjacent the substrate. Apparatus is provided to channel the precursor gas into the positive column away from the negative glow region.
摘要:
The present invention relates to the field of semiconductor processing and provides apparatus and methods that improve chemical vapor deposition (CVD) of semiconductor materials by promoting more efficient thermalization of precursor gases prior to their reaction. In preferred embodiments, the invention comprises heat transfer structures and their arrangement within a CVD reactor so as to promote heat transfer to flowing process gases. In certain preferred embodiments applicable to CVD reactors transparent to radiation from heat lamps, the invention comprises radiation-absorbent surfaces placed to intercept radiation from the heat lamps and to transfer it to flowing process gases.

Es wird eine Vorrichtung zum Versorgen einer Vielzahl von Abnehmerstationen mit einer vorbestimmten Menge eines Prozessmediums, insbesondere eine Beschichtungsvorrichtung für Behälter beschrieben, die eine Zufuhrleitung für das Prozessmedium und einen Anschluss an der Abnehmerstation aufweist. Um eine derartige Vorrichtung konstruktiv einfacher und preisgünstiger auszugestalten, wird vorgeschlagen, eine Einrichtung zum Konstanthalten einer vorbestimmter Durchflussmenge einzusetzen, die eine der vorbestimmten Menge des Prozessmediums entsprechend bemessene Kapillarstrecke vor jedem Anschluss und eine einer Mehrzahl von Anschlüssen zugeordnete Einrichtung zum Aufrechterhalten einer definierten Strömungsgeschwindigkeit über die Kapillarstrecke aufweist.
摘要:
An improved vapor-phase deposition method and apparatus for the application of multilayered films/coatings on substrates is described. The method is used to deposit multilayered coatings where the thickness of an oxide-based layer in direct contact with a substrate (106) is controlled as a function of the chemical composition of the substrate, whereby a subsequently deposited layer bonds better to the oxide-based layer.
