jaAtmosfääripaineCVD

jaAtmosfääripaineCVD, often abbreviated as APCVD, is a chemical vapor deposition technique used in materials science and semiconductor manufacturing. It involves depositing thin films onto a substrate by reacting precursor gases at atmospheric pressure. The process typically occurs within a reaction chamber where the substrate is heated to a specific temperature. Precursor gases are introduced into the chamber, and their chemical reaction at the heated substrate surface leads to the formation and deposition of a solid thin film.

APCVD is known for its relatively simple and cost-effective setup compared to low-pressure CVD techniques. It is capable of depositing a variety of materials, including dielectrics, conductors, and semiconductors. The high deposition rates achievable with APCVD make it suitable for large-scale production. However, the process can sometimes result in films with lower purity or poorer step coverage compared to other CVD methods, especially on complex three-dimensional structures. Despite these limitations, APCVD remains a valuable tool for certain applications where high throughput and cost-efficiency are primary concerns, such as in the production of some types of integrated circuits and protective coatings.
