    摘要: The present invention generally provides a deposition chamber for depositing materials which require vaporization, especially low volatility precursors, which are transported as a liquid to a vaporizer to be converted to vapor phase through one or more vaporizing elements and which must be transported at elevated temperatures to prevent unwanted condensation on chamber components. In one aspect, the chamber comprises a series of heated temperature controlled internal liners as vaporizing surfaces which are configured for rapid removal, cleaning and/or replacement and preferably are made of a material having a thermal coefficient of expansion close to that of the deposition material. The vaporizing surfaces “flash” sprayed liquid precursors on the surface of the vaporizing surfaces and then purify the flashed precursors before flowing further into the system. Particularly contemplated is an apparatus and process for the deposition of a metal-oxide film, such as a barium, strontium, titanium oxide (BST) film, on a silicon wafer to make integrated circuit capacitors useful in high capacity dynamic memory modules. Preferably, internal surfaces of the chamber are adjustable and maintainable at a suitable temperature above ambient, e.g., about 150° C. to about 300° C., to prevent decomposition and/or condensation of vaporized material on the chamber and related gas flow surfaces.

    摘要: The invention relates to an apparatus and process for the vaporization of liquid precursors and deposition of a film on a suitable substrate. Particularly contemplated is an apparatus and process for the vaporization of a metal-oxide film, such as a barium, strontium, titanium oxide (BST) film, for deposition on a silicon wafer to make integrated circuit capacitors useful in high capacity dynamic memory modules. The vaporizer comprises thermally controlled components which are adapted for easy assembly and disassembly. A main vaporizing section provides a large heated surface for flash vaporization. A high conductance blocker is disposed at a lower end of the vaporizer to provide an extended vaporization surface. Optionally, a filter may be employed to capture unvaporized precursor droplets.

    摘要: A tightening mechanism for adjustably setting a tape holder to an immovable state on a tape dispenser includes a tape holder being provided at an axially outer end with a flared round recess, a bushing ring having a bevel wall and being fitted in the flared round recess, and a locating member slightly smaller than the bushing ring for fitly seating in the bushing ring. A turning knob having a spring put thereon is sequentially extended through the locating member and the bushing ring to screw into a fixing bar, on which the tape holder is mounted. When the knob is turned, a tightness of the bushing ring against the flared round recess is progressively changed to thereby adjust the tape holder to different degrees of immobility, allowing the tape dispenser to apply to tapes of different adhesion ability.

    摘要: A packing structure for immovably mounting a tape holder on a tape dispenser includes a rubber seat having a conical body and defining an axially extended central bore. An upper edge of the conical body is provided with a plurality of equally spaced lugs, and a slot is centered between two adjacent lugs to extend downward by a predetermined distance. The seat is connected to an inner end of a sleeve in the tape holder and then mounted on a fixing bar of the tape dispenser. When a turning knob of the tape dispenser is turned to tighten the tape holder against the fixing bar, the conical and slotted seat enhances the tightening effect, and the slots on the seat allow adjusting of a tightness of the tape holder against the fixing bar.
