Abstract:
A single-substrate-processing apparatus for performing a semiconductor, comprising:an airtight process chamber; a worktable having a mount face configured to horizontally support a target substrate within the process chamber; a supply section configured to supply a process gas into the process chamber; an exhaust section configured to vacuum-exhaust the process chamber; a plurality of lifter pins configured to move the target substrate to and from the mount face, the lifter pins being respectively disposed in lifter holes formed through the worktable; a plurality of ventilation holes formed through the worktable; and a plurality of ventilation grooves formed on the mount face, and comprising first ventilation grooves communicating with the lifter holes and second ventilation grooves communicating with the ventilation holes; wherein a gap space between the target substrate and the mount face communicates with an inner space of the process chamber around the worktable through the first and second ventilation grooves, the ventilation holes, and the lifter holes.
