OBS

Chemical vapor deposition (CVD) deposits atoms or molecules by reducing the decomposition of a chemical-vapor precursor species that contains the material to be deposited. The reduction is normally accomplished using hydrogen at an elevated temperature. Decomposition is accomplished by thermal activation. The use of a plasma allows the reduction or decomposition to be done at a lower temperature than using temperature alone.

La deposición de películas delgadas de materiales dieléctricos para separar eléctricamente partes de los dispositivos electrónicos a realizar es inevitable en la mayor parte de los casos. Una de las técnicas mejor establecidas para ello es la deposición en fase vapor asistida por plasma [...], que permite obtener dieléctricos con baja porosidad y uniformes en tallas laterales de sustrato grandes, conformes con la topología del sustrato, y con velocidades de depósito altas.
