(FR) COMPOSANTS DE CHAMBRE À SEMI-CONDUCTEUR POUR COMMANDE DE RÉTRODIFFUSION
Abstract
(EN) Exemplary semiconductor processing systems may include a remote plasma source and a processing chamber. The processing chamber may include a gasbox defining an access into the processing chamber. The systems may include an adapter positioned between the remote plasma source and the processing chamber. The adapter may include a mounting block defining a central aperture. The remote plasma source may be seated on a first surface of the mounting block. The adapter may include a mounting plate characterized by a first surface on which the mounting block is seated. The mounting plate may define a central aperture axially aligned with the central aperture defined through the mounting block. The mounting plate may define a recess in the first surface of the mounting plate extending about the central aperture through the mounting plate. The recess may form a volume between the mounting block and the mounting plate.
(FR) L'invention concerne des exemples de systèmes de traitement de semi-conducteur qui peuvent comprendre une source de plasma distant et une chambre de traitement. La chambre de traitement peut comprendre une boîte à gaz définissant un accès dans la chambre de traitement. Les systèmes peuvent comprendre un adaptateur positionné entre la source de plasma distant et la chambre de traitement. L'adaptateur peut comprendre un bloc de montage définissant une ouverture centrale. La source de plasma distant peut être placée sur une première surface du bloc de montage. L'adaptateur peut comprendre une plaque de montage caractérisée par une première surface sur laquelle le bloc de montage est logé. La plaque de montage peut définir une ouverture centrale alignée axialement avec l'ouverture centrale définie à travers le bloc de montage. La plaque de montage peut définir un évidement dans la première surface de la plaque de montage s'étendant autour de l'ouverture centrale à travers la plaque de montage. L'évidement peut former un volume entre le bloc de montage et la plaque de montage.
