Product Code : ST-Au-5N-Cu
Gold sputtering target has the same properties as precious metal gold (Au). Gold is a chemical element originated from the Anglo-Saxon word gold (aurum in Latin, meaning glow of sunrise). It was early used before 6000 BC and discovered by people from the Middle East. “Au” is the canonical chemical symbol of gold. Its atomic number in the periodic table of elements is 79 with a location at Period 6 and Group 11, belonging to the d-block. The relative atomic mass of gold is 196.966569(4) Dalton, the number in the brackets indicating the uncertainty.
Gold is one of the most beautiful precious metals with a lustrous, yellow luster. It is soft, dense, malleable, ductile, and an excellent conductor of heat and electricity. Deposited films of gold sputtering targets and gold evaporation materials are used as layers in the production of semiconductors, sensors, batteries, and data storage.

Sputtering Targets Requirements
General requirements such as size, flatness, purity, impurity content, density, N/O/C/S, grain size, and defect control. Special requirements include surface roughness, resistance value, grain size uniformity, composition and tissue uniformity, magnetic conductivity, ultra-high density, ultra-fine grains, etc.
Application of Gold Sputtering Target
The gold sputtering target is used for standard scanning electron microscopy (SEM) coating. It is utilized to cover a specimen with a thin layer of conducting material viz. gold. It is needed to prevent the charging of specimens with an electron beam in conventional SEM mode as well as to increase the signal to noise ratio.
Others: Physical vapor deposition (PVD) of thin films, laser ablation deposition (PLD), magnetron sputtering for semiconductor, display, LED and photovoltaic devices.
