Abstract:
A method of crystallizing a thin film of material comprising the steps of:a) depositing a thin film of material over a substrate; b) irradiating regions of the material with a first array of beamlets by positioning a mask comprising the pattern of the first array of beamlets over the regions; c) stepping the mask until a second array of beamlets is positioned at least partially overlapping the regions irradiate by the first array of beamlets; d) irradiating regions adjacent to the regions irradiated by the first array of beamlets; e) stepping the mask until a third array of beamlets is positioned at least partially overlapping the regions irradiated by the first array of beamlets and the second array of beamlets; f) irradiating regions of the material with the third array of beamlets; g) stepping the mask until a forth array of beamlets is positioned at least partially overlap regions of the material irradiated by the third array of beamlets; and h) irradiating regions adjacent to the regions irradiated by the third array of beamlets.
