Sputtering target, physical vapour deposition, PVD metal scrap
Rp123.00
Our Sputtering machine is a piece of vacuum deposition equipment used to deposit a thin film of material onto a substrate using the physical vapor deposition (PVD) process. It works by bombarding a source material (target) with high-energy ions within a plasma, causing atoms to be ejected and condense as a coating on a desired surface.
How It Works:
Vacuum Environment: The chamber is first evacuated to a high vacuum to remove air and potential contaminants.
Gas Introduction: An inert process gas, usually argon (Ar), is flowed into the chamber, and the pressure is regulated.
Plasma Generation: A high voltage is applied between the target (cathode) and the substrate (anode), which ionizes the argon gas and creates a glowing plasma.
Ion Bombardment: Positive argon ions (
Ar+cap A r raised to the positive power
𝐴𝑟+
) are accelerated towards the negatively charged target material.
Ejection and Deposition: The impact of the energetic ions physically knocks atoms off the target surface. These neutral atoms travel through the vacuum chamber and settle onto the substrate, forming a thin, uniform film.
Applications:
Electronics & Semiconductors: Creating interconnects and barrier layers in integrated circuits and transistors.
Optics: Depositing anti-reflective, high-reflectivity, or filtering coatings on lenses and architectural glass.
Data Storage: Manufacturing magnetic and magneto-optical layers for hard disks and CDs.
Solar Technology: Applying conductive and light-absorbing layers in thin-film solar cells.
Medical Devices: Coating implants and surgical instruments with biocompatible and wear-resistant films.
Industrial/Decorative: Providing durable, aesthetically pleasing, and protective finishes on tools, watches, and automotive parts.
