Linear batch chemical vapor deposition system

A linear batch chemical vapor deposition (CVD) system comprising:

• a deposition chamber having a wall with a window therein;
• a substrate carrier disposed in the deposition chamber and having a plurality of receptacles each configured to receive a planar disc substrate, all of the receptacles in the substrate carrier having a diameter and being arranged in a single row that is parallel to a length of the deposition chamber to hold the planar disc substrates in a straight line and horizontal coplanar configuration;
• a showerhead disposed above the substrate carrier and having a plurality of gas injectors, each of the gas injectors having a port in the shape of a linear slot having a length that is greater than the diameters of the receptacles, each of the linear slots being parallel to the linear slots of the other gas injectors and parallel to the single row of receptacles, each of the gas injectors supplying a different gas through the respective one of the ports toward the substrate carrier;
• a translation mechanism coupled to the showerhead and configured to move the showerhead over the substrate carrier in a direction perpendicular to the single row of receptacles;
• a film thickness sensor to acquire film thickness data for a planar disc substrate, the film thickness sensor disposed above one of the planar disc substrates with the window of the deposition chamber therebetween;
• a temperature sensor configured to acquire temperature data for one of the planar disc substrates;
• and
• a heating system comprising at least one heating element and a heating control module for uniformly controlling a temperature of the planar disc substrates.
