A method and system for monitoring crystallization of an amorphous silicon (a-Si) thin film, and a method of manufacturing a thin film transistor (TFT) by using the method and system are disclosed. The method of monitoring the crystallization of the a-Si thin film includes: irradiating light from a light source onto a monitoring a-Si thin film to anneal the monitoring a-Si thin film; annealing the monitoring a-Si thin film and concurrently measuring a Raman scattering spectrum of light scattered by the monitoring a-Si thin film at set time intervals; and calculating a crystallization characteristic value of the monitoring a-Si thin film based on the Raman scattering spectrum.
