A tray for a vaporization vessel that includes a tray having a side wall, a bottom plate, one or more apertures that extend through the bottom plate, and a duct that extends through and from the bottom plate. The tray configured to support a solid reagent to be vaporized. A method of assembling the tray that includes forming a first tray that has the side wall and the bottom plate. A vaporization vessel that includes one or more of the trays.

Vaporization vessel and method

A chemical delivery system includes a bulk container, a run/refill chamber, a first conduit and a second conduit. The bulk container stores a precursor. The run/refill chamber includes a plurality of spaced tubes having a plurality of surfaces for receiving the precursor in vapor form and storing the precursor in solid form. The first conduit connects the bulk container to the run/refill chamber for transporting the precursor from the bulk container to the run/refill chamber in vapor form. The second conduit connects the run/refill chamber to a deposition chamber for transporting the precursor from the run/refill chamber to the deposition chamber in vapor form.

Chemical delivery system and method of operating the chemical delivery system

A solid delivery precursor is described, which is useful for volatilization to generate precursor vapor for a vapor deposition process. The solid delivery precursor comprises solid bodies of compacted particulate precursor, e.g., in a form such as pellets, platelets, tablets, beads, discs, or monoliths. When utilized in a vapor deposition process such as chemical vapor deposition, pulsed chemical vapor deposition, or atomic layer deposition, the solid delivery precursor in the form of solid bodies of compacted particulate precursor provide substantially increased flux of precursor vapor when subjected to volatilization conditions, in relation to the particulate precursor. As a result, vapor deposition process operation can be carried out in shorter periods of time, thereby achieving increased manufacturing rates of products such as semiconductor products, flat-panel displays, solar panels, LEDs, optical coatings, and the like.

Cold sintering of solid precursors

Cleaning of an ion implantation system or components thereof, utilizing temperature and/or a reactive cleaning reagent enabling growth/etching of the cathode in an indirectly heated cathode for an ion implantation system by monitoring the cathode bias power and taking corrective action depending upon compared values to etch or regrow the cathode.

Ion source cleaning in semiconductor processing systems

A method and apparatus for cleaning residue from components of semiconductor processing systems used in the fabrication of microelectronic devices. To effectively remove residue, the components are contacted with a gas-phase reactive material for sufficient time and under sufficient conditions to at least partially remove the residue. When the residue and the material from which the components are constructed are different, the gas-phase reactive material is selectively reactive with the residue and minimally reactive with the materials from which the components of the ion implanter are constructed. When the residue and the material from which the components are constructed is the same, then the gas-phase reactive material may be reactive with both the residue and the component part. Particularly preferred gas-phase reactive materials utilized comprise gaseous compounds such as XeF, XeF, XeF, NF, IF, IF, SF, CF, F, CF, KrF, Cl, HCl, ClF, ClO, NF, NF, NF, NFH, NHF, HOBr, Br, CF, CF, CF, CHF, CHF, CHF, COF, HF, CHF, CHF, CHF, CHF, CHF, CF, and organochlorides such as COCl, CCl, CHCl, CHCland CHCl.
