Abstract:
Pour simplifier la structure d'une source d'ions métalliques, en particulier pour l'implantation de faibles doses de métaux difficilement évaporables dans des tranches de silicium semiconductrices, la source d'ions métalliques comporte une cathode incandescente chauffable électriquement sous la forme d'un filament chauffant à l'intérieur d'une chambre à ions (1a), ledit filament chauffant (3) étant disposé près d'une pièce métallique (6) dans le métal destiné au dégagement d'ions métalliques et placé essentiellement au potentiel dudit métal.
Abstract:
In various embodiments, eroded sputtering targets are partially refurbished by spray- depositing particles of target material to at least partially fill certain regions (e.g., regions of deepest erosion) without spray-deposition within other eroded regions (e.g., regions of less erosion). The partially refurbished sputtering targets may be sputtered after the partial refurbishment without substantive changes in sputtering properties (e.g., sputtering rate) and/or properties of the sputtered films.
Abstract:
Improvement of control of size and structure of nanoclusters with a nanocluster production apparatus is intended. Increase of an obtained amount and a yield of nanoclusters having size and structure, at least one of which is selected, is intended. A nanocluster production apparatus has a vacuum chamber, a sputtering source that generates plasma by pulse discharge, a pulse power supply that supplies a pulsed power to the sputtering source, a first inert gas supply device that supplies a first inert gas to the sputtering source, a nanocluster growth cell stored in the vacuum chamber and a second inert gas introduction device that introduces a second inert gas into the nanocluster growth cell.
