What is MF or Mid-Frequency AC Sputtering?

Mid-Frequency AC SputteringMid-frequency AC Sputtering has become a mainstay of thin film sputtering technologies, particularly for the deposition of dielectric or non-conducting film coatings on surfaces such as solar panels, optical glass such as telescope mirrors or rolls of plastic. It is largely replacing RF Sputtering for coating dielectrics because it operates in the kHz rather than MHz range requiring less sophisticated and expensive power sources and is a process that is adaptable to large scale applications. …

What is PVD Gold Sputtering?

PVD Gold SputteringGold is one of the most beautifully luminescent and valuable metals on Earth because of its ability to throw light, reflect energy and resist tarnishing. PVD or Physical Vapor Deposition Gold Sputtering is commonly used in the watch and jewelry industry to produce coatings that are hard and durable and won’t rub off with constant contact with the skin or clothes and lose it sheen. …

What is HIPIMS? High Power Impulse Magnetron Sputtering

High Voltage Spark

High Power Impulse Magnetron Sputtering or HIPIMS is a relatively recent advance in sputtering technology used for the physical vapor deposition of thin film coatings based upon Magnetron Sputtering with a high voltage pulsed power source. HIPIMS utilizes a very high voltage, short duration burst of energy focused on the target coating material to generate a high density plasma that results in a high degree of ionization of the coating material in the plasma. …

What is RF Sputtering?

magnetron sputtering source

RF or Radio Frequency Sputtering is the technique involved in alternating the electrical potential of the current in the vacuum environment at radio frequencies to avoid a charge building up on certain types of sputtering target materials, which over time can result in arcing into the plasma that spews droplets creating quality control issues on the thin films – and can even lead to the complete cessation of the sputtering of atoms terminating the process. …

What is E-Beam Evaporation?

Electron-Beam Evaporation Equipment

E-Beam or Electron Beam Evaporation is a form of Physical Vapor Deposition in which the target material to be used as a coating is bombarded with an electron beam from a charged tungsten filament to evaporate and convert it to a gaseous state for deposition on the material to be coated. Taking place in a high vacuum chamber, these atoms or molecules in a vapor phase then precipitate and form a thin film coating on the substrate. …

What Is Thin Film Deposition? Deposition Equipment Types

What is Thin Film DepositionThin Film Deposition is the technology of applying a very thin film of material onto a “substrate” surface to be coated, or onto a previously deposited coating to form layers. Thin Film Deposition equipment and  manufacturing processes are at the heart of today’s semiconductor industry, solar panels, CDs, disk drives, medical implants and optical devices industries. …

Thin Film Deposition By Sputtering: Essential Basics

abstract sputtering glow

There are several methods of Thin Film Deposition which is a vacuum technology for applying coatings of pure materials to the surface of various objects. The coatings are usually in the thickness range of angstroms to microns and can be a single material, or multiple materials in a layered structure. …

What is Thin Film Deposition by Thermal Evaporation? Equipment Types

Thin Film Semiconductor Wafers

One of the common methods of Physical Vapor Deposition (PVD) is Thermal Evaporation. This is a form of Thin Film Deposition, which is a vacuum technology for applying coatings of pure materials to the surface of various objects. The coatings, also called films, are usually in the thickness range of angstroms to microns and can be a single material, or can be multiple materials in a layered structure. …
