Disclosed is a rapid energy transfer annealing (RETA) device and process, where an energy plate is used to rapidly absorb the primary photonic energy of the light source, such as a tungsten halogen lamp (or an xenon Arc lamp), to allow temperature elevation. The energy plate faces an amorphous thin film deposited above a glass or plastic substrate and releases the heat energy transferred by a gas or solid medium to the amorphous thin film,, so as to heat the amorphous thin film for transforming the amorphous thin film into a polycrystalline film.
