Direct answer
Semiconductor fabrication facility is a defined term in the International Fire Code (IFC) 2009, in Semiconductor Fabrication Facilities. The code's own words are: “A building or a portion of a building in which electrical circuits or devices are created on solid crystalline substances having electrical conductivity greater than insulators but less than conductors. These circuits or devices are commonly known as semiconductors.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Semiconductor Fabrication Facilities (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Definitions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

What does this term mean?
Semiconductor Fabrication Facility — IFC 2009, Semiconductor Fabrication Facilities:
A building or a portion of a building in which electrical circuits or devices are created on solid crystalline substances having electrical conductivity greater than insulators but less than conductors. These circuits or devices are commonly known as semiconductors.
What must be verified before using this guidance?
Semiconductor Fabrication Facility is defined once in this corpus, in the Semiconductor Fabrication Facilities chapter of the International Fire Code (IFC) 2009:
A building or a portion of a building in which electrical circuits or devices are created on solid crystalline substances having electrical conductivity greater than insulators but less than conductors. These circuits or devices are commonly known as semiconductors.
Where semiconductor fabrication facility is used in the code
The term appears in 3 chapters of the 2009 I-Codes hosted here. The chapters that lean on it hardest are the ones to read next.
| Chapter | Code | Mentions |
|---|---|---|
| Semiconductor Fabrication Facilities | IFC 2009 | 2 |
| Special Detailed Requirements Based on Use and Occupancy | IBC 2009 | 1 |
| Definitions | IFC 2009 | 1 |
The terms semiconductor fabrication facility is built out of
The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what semiconductor fabrication facility covers:
- Building — IBC 2009: Any structure used or intended for supporting or sheltering any use or occupancy.
- Solid — IBC 2009: A material that has a melting point, decomposes or sublimes at a temperature greater than 68°F (20°C).

Frequently asked questions
What is the code definition of semiconductor fabrication facility?
The International Fire Code (IFC) 2009 defines it in Semiconductor Fabrication Facilities as: “A building or a portion of a building in which electrical circuits or devices are created on solid crystalline substances having electrical conductivity greater than insulators but less than conductors. These circuits or devices are commonly known as semiconductors.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Which parts of the code depend on semiconductor fabrication facility?
In this corpus the term is used across 3 chapters, led by Semiconductor Fabrication Facilities in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What is a semiconductor fabrication facility?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Semiconductor Fabrication Facilities: “A building or a portion of a building in which electrical circuits or devices are created on solid crystalline substances having electrical conductivity greater than insulators but less than conductors. These circuits or devices are commonly known as semiconductors.” It is defined in IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
