Bismuth Selenide Sputtering Target Description

A Bismuth Selenide Sputtering Target is a type of ceramic material composed of bismuth and selenium, commonly used in sputtering processes. This target is typically employed in thin film deposition and various specialized applications due to the unique properties of the bismuth-selenium combination.

BismuthBismuth is a chemical element with the symbol “Bi” and an atomic number of 83. The name “bismuth” originates from the German word ‘Bisemutum,’ a corruption of ‘Weisse Masse,’ meaning white mass. It was first used in 1753 and discovered by Claude François Geoffroy. Bismuth is located in Period 6 and Group 15 of the periodic table, belonging to the p-block elements. Its relative atomic mass is approximately 208.98040 Daltons, with the number in parentheses indicating a margin of uncertainty.

SeleniumSelenium is a chemical element with the symbol “Se” and an atomic number of 34. The name “selenium” is derived from the Greek word ‘selene,’ meaning moon. It was first identified in 1817 by Jöns Jacob Berzelius and Johan Gottlieb Gahn, who also later accomplished and announced its isolation. Selenium is located in Period 4 and Group 16 of the periodic table, classified within the p-block elements. Its relative atomic mass is approximately 78.96 Daltons, with the number in parentheses indicating a margin of 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).
