    Abstract: An apparatus comprises a housing having a process space, a support unit supporting the substrate in the process space, a process gas supply unit supplying a process gas into the process space, and a plasma source generating plasma from the process gas. The support unit comprises a support member on which the substrate is placed, a heating member that heats the substrate supported on the support member, and a heat transfer gas supply member that supplies a heat transfer gas to a backside of the substrate. The heating member comprises heaters that heat regions on the substrate on the support member viewed from above. The support member comprises a protrusion that partitions a space between the support member and the backside of the substrate placed on the support member into gas regions, and at least one of heating regions is divided into regions by the protrusion viewed from above.
