The Tokyo Electron Trias is a chemical vapor deposition (CVD) system. The Trias is manufactured by Tokyo Electron. The Trias model designation is Trias.[1][2][3][4][5]
What it is
How it works
General reference — not yet source-verifiedA CVD tool such as the Trias introduces precursor gases into a reaction chamber, where they undergo a chemical reaction at the heated substrate surface, forming a solid film. By-products are removed by the gas flow. The process can be carried out at low pressure or with plasma enhancement to lower deposition temperatures.
Where it fits in the process flow
General reference — not yet source-verifiedIn a semiconductor fab, CVD tools are used after surface preparation and before patterning or metallization steps. The Trias can be employed in both front-end-of-line and back-end-of-line process flows for depositing dielectric or insulating layers. Upstream steps typically include cleaning and oxidation; downstream steps may involve etch or chemical-mechanical planarization.
