HB6055, the “SEMI Investment Act,” would amend the Internal Revenue Code to expand and extend the advanced manufacturing investment credit for semiconductor-related facilities. The bill broadens the definition of an “advanced manufacturing facility” to include facilities primarily engaged in manufacturing semiconductors, semiconductor manufacturing equipment, or semiconductor materials. It also creates detailed definitions for “semiconductor materials,” distinguishing between direct production materials that are physically incorporated into a finished semiconductor and indirect production materials used in production, testing, inspection, packaging, and related processes.
The bill specifically identifies a wide range of covered inputs, including substrates, thin-film and layering materials, packaging substrates, bonding and interconnect materials, process chemicals, photolithography materials, cleaning and planarization materials, testing and inspection materials, packaging process materials, wafer-handling materials, and certain chamber materials. It also authorizes the Secretary of the Treasury, in consultation with the Secretary of Commerce, to publish and update a list of qualifying materials and to determine additional qualifying materials through taxpayer petitions. In addition, the bill extends the credit period by changing the sunset date from December 31, 2026, to December 31, 2031.
If enacted, the bill would affect federal tax law by expanding eligibility for the semiconductor manufacturing investment credit under section 48D of the Internal Revenue Code and by lengthening the time during which qualifying property can receive the credit. The practical effect would be to increase the number of semiconductor supply-chain investments that may qualify for tax incentives, including upstream materials and process inputs that were not clearly covered under the narrower existing definition.
The available context shows no committee debate or recorded votes, so there is no documented public sentiment in the materials provided. Based on the bill’s sponsorship and structure, it appears to have been framed as a pro-manufacturing, pro-semiconductor-supply-chain measure intended to strengthen domestic industrial investment and support U.S. chip production capacity.
No specific points of contention are recorded in the provided context, but the bill’s detailed material definitions and the Treasury/Commerce determination process suggest possible areas of debate over how broadly the credit should apply, which materials should qualify, and whether the extension and expansion of the tax credit is an appropriate federal incentive. Potentially affected parties include semiconductor manufacturers, equipment suppliers, materials producers, and taxpayers seeking to claim the credit.
The bill would amend section 48D of the Internal Revenue Code to expand the scope of the advanced manufacturing investment credit and extend its availability through property construction beginning after December 31, 2026, with the credit period running through December 31, 2031. It would also require Treasury, in consultation with Commerce, to identify qualifying semiconductor materials and allow taxpayers to petition for determinations, thereby broadening federal tax incentives for semiconductor and related manufacturing investments.
No votes or committee transcripts are provided, so there is no recorded legislative sentiment in the available materials. The bill’s text and title indicate a generally supportive, industry-promoting purpose focused on strengthening domestic semiconductor manufacturing and industrial investment.
The main potential contention is the breadth of the expanded credit: the bill covers not only finished semiconductor facilities but also a wide array of direct and indirect materials used in fabrication, testing, inspection, and packaging. Another possible point of debate is the administrative role given to Treasury and Commerce in defining qualifying materials, which could affect how expansive or restrictive the credit becomes. No specific objections or supporters are documented in the provided context.
