본 명세서에 설명된 실시예들은 일반적으로 서셉터를 프로세스 챔버에 결합하기 위한 스템 어셈블리에 관한 것이다. 스템 어셈블리는 피벗 메커니즘; 피벗 메커니즘에 결합된 제1 가요성 밀봉부; 플레이트의 제1 면 상에서 플레이트에 결합된 제2 가요성 밀봉부 - 플레이트는 제1 가요성 밀봉부에 결합된 제2 면을 가짐 -; 제2 가요성 밀봉부에 결합된 하우징; 및 하우징을 X 축 및 Y 축으로 이동시키고 서셉터를 프로세스 챔버의 X-Y 평면에 대하여 각도적으로 위치시키도록 되어 있는 모션 어셈블리를 포함한다. The embodiments described herein generally relate to a stem assembly for coupling a susceptor to a process chamber. The stem assembly includes a pivot mechanism, a first flexible seal coupled to the pivot mechanism, a second flexible seal coupled to a plate on a first side of the plate, the plate having a second side coupled to the first flexible seal, a housing coupled to the second flexible seal, and a motion assembly adapted to move the housing in an X axis and a Y axis, and position the susceptor angularly relative to an X-Y plane of the process chamber.
