What is sputtered film?

Sputtered film tinting is a window film that is constructed from metal alloys, which is combined in a vacuum chamber with different gasses; and then applied onto the window.

Which type of technology is used in thin film?

Techniques used for epitaxial growth of thin films include molecular beam epitaxy, chemical vapor deposition, and pulsed laser deposition.

What is the sputtering technique?

Sputtering is a physical process in which atoms in a solid-state (target) are released and pass into the gas phase by bombardment with energetic ions (mainly noble gas ions). Sputtering is usually understood as the sputter deposition, a high vacuum-based coating technique belonging to the group of PVD processes.

What is sputtered on the whole wafer?

Explanation: Aluminium is sputtered on the whole wafer before removing the excess metal from the wafer.

What is the advantage of sputtering?

An important advantage of sputter deposition is that even materials with very high melting points are easily sputtered while evaporation of these materials in a resistance evaporator or Knudsen cell is problematic or impossible. Sputter deposited films have a composition close to that of the source material.

Why is sputtering useful?

Sputter deposition is widely used to deposit thin film metallization on semiconductor material, coatings on architectural glass, and reflective coatings on compact discs (CDs), and for magnetic films, dry film lubricants, hard coatings (tools, engine parts), and decorative coatings.

Why is thin film technology important?

Thin films are generally used to improve the surface properties of solids. Transmission, reflection, absorption, hardness, abrasion resistance, corrosion, permeation and electrical behaviour are only some of the properties of a bulk material surface that can be improved by using a thin film.

What is thin film semiconductor?

In general, semiconductor thin films are produced in one or more thin layers. Common applications of such structures include many electronic materials such as transistors, sensors, and photovoltaic devices.

What are the types of sputtering?

Several types of sputtering systems are used in practice including DC diode, RF-diode, magnetron diode, and ion beam sputtering.

What are the advantages of BiCMOS?

It follows that BiCMOS technology offers the advantages of: 1) improved speed over CMOS, 2) lower power dissipation than Bipolar (simplifying packaging and board requirements), 3) flexible I/Os (TTL, CMOS, or ECL), 4) high performance analog, and 5) latchup immunity [1.2].
