Abstract:
A single-substrate-heat-treating apparatus for a semiconductor process system, comprising:an airtight process chamber;a worktable arranged within said process chamber and having a top surface configured to place a target substrate thereon;an exhaust mechanism configured to exhaust said process chamber;a supply mechanism configured to supply a process gas into said process chamber; anda heating mechanism configured to heat said target substrate placed on said worktable;wherein said supply mechanism comprises a shower head including an outside pipe having a ring shape with a diameter larger than a diameter of said target substrate, and inside pipes connected to an inside of said outside pipe and combined to form a lattice, and wherein said inside pipes are provided with first spurting holes for spouting said process gas downward, in a first direction toward the target substrate, and part of said inside pipes defining a central opening of said shower head are provided with second spurting holes for spouting said process gas inward in a second direction perpendicular to the first direction, such that flows of the process gas spouted from said second spurting holes hit each other and form flows flowing downward in the first direction to be supplied to a center of the target substrate.
