Plasma sputtering is a technique used in material science and engineering to deposit thin films on a substrate by bombarding a target material with energetic ions from a plasma, causing atoms to be ejected and settle onto a surface. This versatile process enables precise control over film thickness and composition, making it integral for applications like semiconductor fabrication and coating technologies.

Material science and engineering

Thin films are layers of material ranging from fractions of a nanometer to several micrometers in thickness, used to modify surface properties or fabricate microelectronic devices. They play a crucial role in various industries, including semiconductors, optics, and photovoltaics, due to their unique physical and chemical properties that differ from bulk materials.

Thin Films

A substrate is the underlying substance or layer that supports or is the surface on which an organism grows or is attached, or it is the substance on which an enzyme acts in biochemical reactions. Understanding substrates is crucial in fields such as biology, chemistry, and environmental science as they influence the behavior and interaction of organisms and reactions.

Substrate

Target material refers to the specific substance or element that is subjected to a process or experiment, often to observe its reactions or properties under certain conditions. It plays a crucial role in fields like physics, chemistry, and materials science, where understanding its interactions can lead to advancements in technology and scientific knowledge.

Target Material

Energetic ions

Plasma is a state of matter, distinct from solids, liquids, and gases, characterized by its unique properties such as being electrically conductive and responsive to magnetic fields. It is composed of free electrons and ions and is found naturally in stars, including the sun, and artificially in neon lights and plasma TVs.

Atoms

A surface is a two-dimensional manifold that represents the boundary or outermost layer of a three-dimensional object. It is a fundamental concept in geometry and topology, playing a crucial role in fields such as physics, engineering, and computer graphics for modeling and analyzing shapes and spaces.

Surface

Film thickness refers to the measurement of the depth or thickness of a film or coating layer, which is crucial for ensuring the desired performance and functionality of the material. Accurate measurement and control of film thickness are essential in various industries to optimize product quality, durability, and efficiency.

Film Thickness

Composition refers to the arrangement and organization of elements within a work, whether in art, music, or writing, to create a harmonious and effective whole. It is foundational in guiding the viewer or reader’s experience and in conveying the intended message or emotion of the creator.

Composition

Semiconductor fabrication is a complex, multi-step process that involves creating integrated circuits on semiconductor wafers, primarily silicon. It requires precision engineering and advanced technologies to achieve the miniaturization and performance enhancements needed for modern electronic devices.

Semiconductor Fabrication

Coating technologies involve the application of a layer or covering to a surface to enhance its properties, such as durability, appearance, or resistance to environmental factors. These technologies are crucial in various industries, including automotive, aerospace, and electronics, for improving product performance and extending lifespan.
