Abstract:
A closed chemical introduction system used to deliver active ingredients in liquid chemical to a chemical vapor deposition system includes a robust, moisture-free cartridge containing a defined dose of liquid chemical. The cartridge is placed on a mounting slot specially configured to receive the cartridge. Upon initiating the system, a first linear mechanical actuator securely holds the cartridge in the slot, while an extraction lance attached to a second linear mechanical actuator punctures the cartridge from the bottom, extracts the liquid chemical and delivers it to a vaporization chamber. The vaporization chamber evaporates the liquid chemical and delivers the vapors containing the active ingredients to the chemical vapor deposition system. The chemical vapor deposition system may include a treatment chamber, a conveyor, a compressed clean air system to provide separate treatment compartments within the chamber, a moisture system, a chemical vapor system, and a neutralization system to neutralize harmful byproducts.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung von polykristallinem Silicium, bei dem ein Reaktionsgas enthaltend eine Silicium enthaltende Komponente und Wasserstoff in einen Reaktor eingeleitet wird, wobei der Reaktor wenigstens einen Trägerkörper aus Silicium umfasst, der durch direkten Stromdurchgang erhitzt wird, wobei die Silicium enthaltende Komponente zersetzt wird und sich polykristallines Silicium auf dem wenigstens einen Trägerkörper abscheidet, dadurch gekennzeichnet, dass der wenigstens eine Trägerkörper aus Silicium eine Oxidschicht aufweist, die vor Beginn der Abscheidung von polykristallinem Silicium auf dem wenigstens einen Trägerkörper dadurch entfernt wird, dass der wenigstens eine Trägerkörper auf eine Temperatur von 1100-1200°C aufgeheizt und bei einem Druck von 0,1 bis 5 barü einer Atmosphäre enthaltend Wasserstoff ausgesetzt wird, indem ein Spülgas enthaltend Wasserstoff dem Reaktor zugeführt wird.
Abstract:
A reactor device (1) for chemical vapour deposition comprises a reaction chamber (4) having a purge gas inlet (106). A gas discharge channel (100) is linked to said reaction chamber (4) via a circumferential opening (49a) in the inner wall (19) of said chamber. The reaction chamber (4) is arranged such that a purge gas stream (200) flows from the purge gas inlet (106) to the discharge channel (100). Said inner wall (19) of the reaction chamber comprises means for exchanging heat with the purge gas, for example fins.
Abstract:
Atomic layer deposition (ALD) processes for forming Group VA element containing thin films, such as Sb, Sb-Te, Ge-Sb and Ge-Sb-Te thin films are provided, along with related compositions and structures. Sb precursors of the formula Sb( SiR1R2R3)3 are preferably used, wherein R1, R2, and R3 are alkyl groups. As, Bi and P precursors are also described. Methods are also provided for synthesizing these Sb precursors. Methods are also provided for using the Sb thin films in phase change memory devices.

Abstract:
A decorative coating and a method for forming a decorative coating on a substrate (2). The decorative coating comprises an absorbing film (1) to attenuate the transmission of visible light through the coating. The method comprises the steps of bringing the substrate (2) into a reaction space, and depositing the absorbing film (1) on the substrate (2). Depositing the absorbing film (1) on the substrate comprises the steps of forming a preliminary deposit of transition metal oxide on the deposition surface and subsequently purging the reaction space, and treating the deposition surface with an organometallic chemical comprising first metal and subsequently purging the reaction space. The steps of forming the preliminary deposit and treating the deposition surface are alternately repeated to increase absorption of the absorbing film (1).
