Gas phase etching device and gas phase etching apparatus are provided. The gas phase etching device includes: a reaction chamber body, defining a space as a reaction chamber; a pedestal, disposed inside the reaction chamber for holding a workpiece; an inlet member, connected to the reaction chamber body for introducing etchants into the reaction chamber; a pressure regulating assembly, connected to the reaction chamber body for regulating a pressure inside the reaction chamber; a first temperature controller, connected to the reaction chamber body for controlling a temperature therein to a first temperature; and a second temperature controller, connected to the pedestal for controlling a temperature to a second temperature. The first temperature is a temperature that prevents the reaction chamber from being corroded by the etchants. The second temperature is a temperature under which the workpiece held by the pedestal satisfies a temperature requirement for directly performing a subsequent process.
