Explore MIPI PCB design guidelines for CSI, DSI, and PHY interfaces, ensuring high-speed data transfer and signal integrity in your PCB designs.

John Burkhert shares his design experience and talks about the four biggest mistakes he's made during his career as a PCB designer, so that you can try and avoid them in your career as well.

Both techniques play pivotal roles in ICs. Generally, vapor deposition is best suited for processes in IC manufacturing and sputtering is best suited for IC packaging.

Within the realm of electronics design, a process called thin-film deposition transforms raw materials into functional components for things such as microchips, optical lenses, and photovoltaic panels. For Integrated Circuit (IC) manufacturing and packaging, the most applicable methods of thin-film deposition are Vapor Deposition and  Sputtering.

Ion Beam Sputtering: Ions are accelerated and focused into the target material, dislodging atoms or molecules that subsequently deposit on the substrate. Ion beam sputtering offers exceptional precision and control, making it suitable for applications demanding extreme film quality, such as optical coatings.

If application uniformity and substrate compatibility are the goal, then sputtering is the most appropriate method of thin-film application. Sputtering is best for:

Physical Vapor Deposition (PVD): Thermal evaporation removes raw material from a solid source. The vaporized material is then transported to the substrate, where it condenses into a solid film. PVD is widely favored for its ability to produce high-quality, dense films and is frequently used in applications where precise control over film thickness is paramount.

Thin-film deposition is a process within electronic design that transforms solid materials into thin, functional layers on substrates.

Vapor deposition creates insulating layers between the metal interconnects in ICs to ensure electrical isolation between the conductive parts of the semiconductor device

Sputtering is a process by which a solid material is bombarded with high-energy ions, ejecting molecules onto a nearby substrate to form a thin film. Within the range of sputtering techniques, there are two prominent variations.

Whether through sublimation, evaporation, or chemical reaction, vapor deposition is a process by which a raw material is transformed into a gaseous state and subsequently deposited onto a substrate, forming a thin film of the material on the substrate's surface. There is an array of techniques, but physical vapor deposition and chemical vapor deposition are two of the most prominent.

The needs of the situation are what determine which thin-film deposition method is the best. If application precision and high-quality film are the goal, then vapor deposition is the most appropriate method of thin-film application. Vapor deposition is best for:

Vapor deposition is a technique that converts solid materials into a gaseous state and then deposits them as a thin film on substrates. Sputtering is a deposition technique where material atoms are ejected from a solid target and then deposited as a thin film on nearby substrates.

Magnetron Sputtering: Magnetic fields near the target material enhance plasma confinement and ensure a more efficient, stable sputtering process. Magnetron sputtering is known for its ability to produce uniform, high-quality films with superior adhesion.

Chemical Vapor Deposition (CVD): Chemical reactions between gaseous precursors deposit a solid material on the substrate through variations like laser CVD, atomic layer deposition, etc. CVD’s superior conformal coating capabilities make it suitable for complex 3D structures, integrated circuits, and protective coatings.
