Claim Objections
The previous objections to claims 9, 14, and 17 are withdrawn based on the amendment to claims 9, 14, and 17.
Claim Interpretation
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are : “processing apparatus” and “delivery mechanism” in claim 9.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.

(See Lam, Abstract, Figs. 1-6, paragraphs 25-33, and 37.)
Lam teaches an evaporator (180), but does not explicitly teach an evaporator configured to evaporate the solvent of the solution delivered from the delivery mechanism and accommodated in the vaporizer to separate the solid raw material.
Marganski is directed to system for delivery of reagents from solid sources.
Marganski teaches an evaporator (276) configured to evaporate the solvent of the solution delivered from the delivery mechanism and accommodated in the vaporizer (276) to separate the solid raw material (solid source material). (See Marganski, Abstract, paragraphs 113-115, 221-229, 233; and Fig. 6.)
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include an evaporator configured to evaporate the solvent of the solution delivered from the delivery mechanism and accommodated in the vaporizer to separate the solid raw material; because Marganski teaches this structure enables separation of the solvent from the solid and facilitates the refurbishment and reuse of the supply vessel and materials after the volatilization operation is complete. (See Marganski, Abstract, paragraphs 113-115, 221-229, 233; and Fig. 6.)
Additionally regarding claim 9, Lam teaches the vaporizer includes a container, a tray assembly provided in the container, and a plurality of shelves (trays 112) configured to accommodate the solution (hold liquid precursor). (See Lam, Abstract, Figs. 1-6, paragraphs 25-33, and 37.)
Additionally regarding claim 9, Lam teaches the plurality of shelves (trays 12) are stacked in a vertical direction. (See Lam, Abstract, Figs. 1-6, paragraphs 25-33, and 37.)

Regarding claims 14 and 17, Lam does not explicitly teach a plurality of vaporizers including a first vaporizer and a second vaporizer connected in parallel with one another; and a controller configured to output a control signal which allows, when the first vaporizer of the plurality of vaporizers is in a state capable of supplying the raw material gas to the processing apparatus, the solution to be delivered from the solution source to the second vaporizer of the plurality of vaporizers such that the solid raw material is separated from the solution in the other part of the plurality of vaporizers
Logue teaches using a plurality of vaporizers in a deposition process.
Logue teaches include a plurality of vaporizers (126 or 128) connected in parallel with one another; and a controller (automatic user interface 114) configured to output a control signal which allows, when a part of the plurality of vaporizers (126 is in a state capable of supplying the raw material gas to the processing apparatus (142), the solution to be delivered from the solution source to the other part of the plurality of vaporizers (128) such that the solid raw material is separated from the solution in the other part of the plurality of vaporizers (128). (See Logue, Abstract, Figs. 1-3, paragraphs 6, 11, 21, 23, 29, 30, 37, 41-51, 54.) (Examiner is considering utilizing the other vaporizer (128) supplying high pressure output to the reactor when the first vaporizer (126) is suppling low pressure output to be equivalent to when a part of the plurality of vaporizers is in a state capable of supplying the raw material gas to the processing apparatus, the solution to be delivered from the solution source to the other part of the plurality of vaporizers such that the solid raw material is separated from the solution in the other part of the plurality of vaporizers based on paragraphs 49-57.) Examiner is considering a control configured to output a control signal to be equivalent to an automatic interface.
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include a plurality of vaporizers including a first vaporizer and a second vaporizer connected in parallel; and a controller configured to output a control signal which allows, when the first vaporizer of the plurality of vaporizers is in a state capable of supplying the raw material gas to the processing apparatus, the solution to be delivered from the solution source to the second vaporizer of the plurality of vaporizers such that the solid raw material is separated from the solution in the other part of the plurality of vaporizers; because Logue teaches this structure allows precursor gas can be accumulated to provide run-to-run and tool-to-tool matching based on the controlled and stable delivery of flux. (See Logue, Abstract, Figs. 1-3, paragraphs 6, 11, 21, 23, 29, 30, 37, 41-51, 54.)

Response to Arguments
Applicant’s arguments with respect to claims 9-10, 14, and 17 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
US 20150191819 A1 to Hendrix et al Assignee: Entegris, Inc. (hereinafter Hendrix) is being used to address the limitations added to claim 9 in a first set of rejections.

Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US Pat. Pub. No. 20100255198 A1 to Cleary et al teaches projections disposed in a spiral assembly in a sublimator or vaporizer. (See Cleary, paragraph 194, and Fig. 9.)
