Aluminum Silicon Sputtering Target Description

The aluminum silicon sputtering target from TFM is an alloy sputtering material composed of aluminum (Al) and silicon (Si).

Aluminum

Aluminum:

Aluminum, also known as aluminium, gets its name from the Latin word for alum, ‘alumen,’ meaning bitter salt. It was first mentioned in 1825 by H.C. Ørsted, who also successfully isolated it. The chemical symbol for aluminum is “Al,” and it has the atomic number 13. It is located in Period 3 and Group 13 of the periodic table, within the p-block. The relative atomic mass of aluminum is 26.9815386(8) Dalton, with the number in brackets indicating the uncertainty.

Silicon

Silicon:

Silicon is a chemical element named after the Latin words ‘silex’ or ‘silicis,’ meaning flint. It was first mentioned and observed in 1824 by J. Berzelius, who also succeeded in isolating it. The chemical symbol for silicon is “Si,” and it has the atomic number 14. Silicon is located in Period 3, Group 14 of the periodic table, belonging to the p-block. The relative atomic mass of silicon is 28.0855(3) Dalton, with the number in brackets indicating the uncertainty.

FAQ

It’s the source material (in solid form) used in sputter deposition to eject atoms or molecules that then form a thin film on a substrate.

Targets can be pure metals (e.g., gold, copper, aluminum), ceramics (e.g., Al₂O₃, SiO₂, TiO₂), alloys, or composites—chosen based on the film’s desired properties.

 

They are produced by processes such as melting/casting for metals or sintering (often with hot isostatic pressing) for ceramics and composite targets to ensure high density and purity.

 

In a vacuum chamber, a plasma (typically argon) bombards the target, ejecting atoms that travel and condense on a substrate, forming a thin film.

 

Key factors include the target’s purity, density, grain structure, and the sputtering yield (i.e. how many atoms are ejected per incident ion), as well as operating conditions like power density and gas pressure.

 

Operators monitor target erosion (often by measuring the depth of the eroded “race track”) or track total energy delivered (kilowatt-hours) until it reaches a threshold that can compromise film quality.

 

Fragile materials (such as many ceramics or certain oxides) and precious metals often require a backing plate to improve cooling, mechanical stability, and to allow thinner targets that reduce material costs.

 

DC sputtering is used for conductive targets, while RF sputtering is necessary for insulating targets (like many oxides) because it prevents charge buildup on the target’s surface.

 

In reactive sputtering, a reactive gas (e.g., oxygen or nitrogen) is introduced to form compound films on the substrate, but it may also “poison” the target surface if not carefully controlled.

 

Many manufacturers prefer to control raw material quality by sourcing their own powders; using external powders can risk impurities and inconsistent target properties.

 

Targets should be stored in clean, dry conditions (often in original packaging or re-wrapped in protective materials) and handled with gloves to avoid contamination, ensuring optimal performance during deposition.

Deposition rate depends on factors such as target material and composition, power density, working gas pressure, substrate distance, and the configuration of the sputtering system (e.g., magnetron design).
