Onex Communications Corporation (Onex) was formed in 1999 to design and sell integrated circuits for use in the telecommunications industry.1 Its efforts yielded the OMNI *644chip,2 early versions of which were produced, sold, and tested in 2001 before the device became generally available on the market in 2002. Able to accommodate thirty-two distinct voice channels on each of its 1,344 virtual circuits, a single OMNI chip could perform the work of ten chips made with prior technology. The product was revolutionary for its time and enabled substantial reductions in power use and system costs.

In 2002, the Department of Revenue (department) audited Onex’s purchases of personal property. The audit period began on August 1, 1999, and extended through September 21, 2001.3 Over the course of the audit period, Onex had purchased $2,723,510 of personal property for research and development (R&D) purposes, paying neither sales nor use tax. In December, 2002, the Commissioner of Revenue (commissioner) advised Onex that its R&D purchases had been taxable and that the department intended to assess use taxes of $136,175 plus interest and penalties. Onex requested an abatement, contending that the items purchased were “materials, machinery and replacement parts . . . used directly and exclusively in R&D” and were, as such, exempted from the use tax by G. L. c. 64H, § 6(r) and (s), as incorporated by G. L. c. 641, § 7(b).4 The request was denied on the grounds that Onex had qualified as neither a manufacturing nor a research and development corporation under G. L. c. 63, §§ 38C or 42B.5 In the circumstances, at least one such qualification was necessary for Onex’s R&D purchases to come within *645the scope of the exemptions set forth in G. L. c. 64H, § 6(r) and (S).

Onex challenged the denial of its requested abatement before the Appellate Tax Board (board). The board ruled that Onex had been a manufacturing corporation within the meaning of G. L. c. 63, § 42B, throughout the audit period, and that assessment of the use tax had been improper.6 Because we agree that Onex qualified as a § 42B manufacturing corporation throughout the audit period, we affirm the board’s order directing a use tax abatement of $136,175 and cancellation of all penalties and interest.

“Finished product” limitation. The commissioner maintains that Onex could not have been a manufacturing corporation during the audit period essentially because, at the conclusion of that period, Onex had yet to achieve a finished product.7 That analysis may have superficial appeal, but it is not compelled by the statute. Indeed, the statutory text does little, if anything, to clarify what exactly the Legislature intended to qualify within the ambit of manufacturing. The relevant provision, G. L. c. 63, § 42B, states only that a “manufacturing corporation” is one “engaged in manufacturing.” See Commissioner of Rev. v. Houghton Mifflin Co., 423 Mass. 42, 44 (1996).8

*646The pertinent decisional law, moreover, ascribes a far broader meaning to manufacturing than the minimalist interpretation urged by the commissioner. Massachusetts cases instruct that “[t]he words ‘engaged in manufacturing’ are not to be given a narrow or restricted meaning.” Assessors of Boston v. Commissioner of Corps. & Taxn., 323 Mass. 730, 748-749 (1949). Rather, the phrase is to be fairly construed and reasonably applied to effectuate legislative intent. Id. at 741. We have long inferred, without contradiction from the Legislature, that the tax exemption at issue was intended “[to] induc[e] new industries to locate [in the Commonwealth] and to foster the expansion and development of [its existing] industries . . . .’’Ibid. Set Houghton Mifflin Co., 423 Mass. at 46-47.

That purpose would be substantially frustrated were we to interpret §§ 38C and 42B to mean that no corporation may be designated a manufacturing corporation until it has achieved its intended finished product. In particular, we note that such a policy would place new or specialized corporations in a highly disadvantageous tax position. Consider the R&D purchases of an established corporation that, in addition to its R&D efforts, engages in the assembly and sale of an entirely unrelated product. Provided these latter, clearly manufacturing activities are substantial, the corporation will be entitled to classification as a manufacturing corpora*647tion, and its R&D purchases, despite their irrelevance to the corporation’s existing finished product, will be exempt from sales and use taxation.9 Now consider identical R&D purchases, made in furtherance of R&D efforts identical to those underway at the established corporation, but this time by a new corporation that has no preexisting finished product. Under the commissioner’s interpretation of the statute, the new corporation would be barred from qualifying as a manufacturing corporation and its R&D purchases would be subject to taxation.10 That result is arbitrary and inimical to the Legislature’s purpose in enacting the statute.

Classification of Onex’s activities. Having dispensed with the commissioner’s contemplated finished product limitation, we must now consider at what times, if any, Onex was engaged in substantial manufacturing activities.

We first note, but do not rely on, an amendment to §§ 38C and 42B that took effect in 2006, several years after the present assessment against Onex. “[T]he development and sale of standardized computer software,” the text added by the amendment reads, “shall be considered a manufacturing activity, without regard to the manner of delivery of the software to the customer.” G. L. c. 63, §§ 38C, 42B, as amended through St. 2005, c. 163, §§ 27, 29, 59. Enactment of this language, which brings the creation of intangible software products within the statutory definition of manufacturing, cannot be reconciled with a legislative conception of manufacturing that is confined to the assembly line. Even before the aforementioned amendment to §§ 38C and 42B, however, Onex’s activities would properly have been classified as manufacturing.

The board found, on substantial evidence, that Onex was *648founded for the purpose of designing and manufacturing a microchip device to enhance data transmission over communications networks. Work on that device, ultimately branded as the OMNI chip, began from a blank sheet of paper. Onex engineers created, refined, integrated, and embedded OMNI’s numerous software and hardware components. From a physical standpoint, the board’s findings establish that “[t]iny internal modules had to be interwoven, integrated, and laid out to enable the intended functionality.” To that end, Onex engineers drafted intricate electronically-stored “blueprints” to direct, with absolute precision, the physical construction of the OMNI chip from raw silicon and the embedding of the software into the hardware.11 Testimony credited by the board established that the development of these blueprints “was an essential step in manufacturing the OMNI chip.” In sum, the board properly found, on the basis of the evidence before it, that “Onex’s activities during the audit period centered on taking the OMNI chip from abstract concept to production.” It then ruled, as matter of law, that the entirety of this process constituted manufacturing. We agree. “[PJrocesses which do not in themselves produce a finished product are nonetheless ‘manufacturing’ if they comprise an ‘essential and integral part of a total manufacturing process.’ ” Houghton Mifflin Co., 423 Mass. at 47, quoting from William F. Sullivan & Co. v. Commissioner of Rev., 413 Mass. 576, 580 (1992).

In Houghton Mifflin Co., 423 Mass. at 50, the court held that the creation of electronic proofs of the pages of a textbook constituted manufacturing. Preparation of the proofs began with editors, generally employees of Houghton Mifflin, engaging in “extensive research and development activities regarding a proposed book” to assess marketability and determine potential *649content and formatting. Id. at 43. Composition and editing of a manuscript followed, in addition to the creation or gathering of illustrative charts, graphs, drawings, and photographs. Id. at 43-44. The exact placement of these various items was specified in the electronic proofs ultimately sent to outside vendors for printing and binding. Id. at 44, 50-51. As such, the court observed that “[Houghton Mifflin] transforms ideas, art, information, and photographs, by application of human knowledge, intelligence, and skill, into computer disks, ready for use by independent printers, containing an immense amount of information in a highly organized form” and concluded that these activities sufficed to warrant designation as a manufacturing corporation. Id. at 48, 50-51. In reaching this conclusion, the court emphasized that the electronic proofs were not “valued solely for their artistic and intellectual content” but were, rather, “valuable principally because they [were] physically useful in making the finished product.” Id. at 49. See Commissioner of Rev. v. Fashion Affiliates, Inc., 387 Mass. 543, 545-546 (1982). The court, we note, was not concerned with whether the finished product had yet materialized. Its inquiry instead focused on the manufacturing process that was underway — one which, the context makes clear, was reasonably calculated to culminate in a finished product. The court agreed with the board that Houghton Mifflin’s operations “produce a significant degree of change and refinement to the materials involved and ... are essential and integral steps in the manufacture of conventional books.” Houghton Mifflin Co., 423 Mass. at 49. The court specifically acknowledged that some of the “materials” involved were intangible. Id. at 48.

The board’s ruling here drew many sound comparisons between Onex’s activities during the audit period and the manufacturing process delineated in Houghton Mifflin Co., supra. Onex’s creation of blueprints, the purpose of which was to direct with absolute specificity the manner in which the OMNI chip was to be assembled, does not admit of meaningful differentiation from Houghton Mifflin’s creation of electronic proofs of textbook pages. In each instance, a vast amount of information was marshaled in a manner sufficient to permit, and for the express purpose of permitting, assembly of a physical object intended to unleash the benefit of the information so organized. The board properly *650found that Onex’s activities throughout the audit period were directed toward devising and refining the blueprints that specified how to assemble the OMNI chip. As such, all of Onex’s activities during that period were essential and integral to the total manufacturing process, a circumstance entitling Onex to classification as a manufacturing corporation.

Conclusion. The decision of the board is affirmed in all respects.

So ordered.
