AbstractA novel method to control the recrystallization depth of amorphous silicon (a-Si) film during the excimer laser annealing (ELA) is proposed in order to preserve a-Si that is useful for fabrication of poly-Si TFT with a-Si offset in the channel. A XeCl excimer laser beam is irradiated on a triple film structure of a-Si thin native silicon oxide (~20Å)/thick a-Si layer. Only the upper a-Si film is recrystallized by the laser beam irradiation, whereas the lower thick a-Si film remains amorphous because the thin native silicon oxide layer stops the grain growth of the poly-crystalline silicon (poly-Si). So that the thin oxide film sharply divides the upper poly-Si from the lower a-Si.

AbstractAn ultra-low temperature (< 200°C) polycrystalline silicon (poly-Si) film is fabricated for the plastic substrate application using inductively coupled plasma chemical vapor deposition (ICP-CVD) and excimer laser annealing. The precursor active layer is deposited using the SiH4/He mixture at 150°C (substrate). The deposited silicon film consists of crystalline component as well as hydrogenated amorphous component. The hydrogen content in the precursor layer is less than 5 at%. The grain size of the precursor active silicon film is about 200nm and it is increased up to 500nm after excimer laser irradiation.

AbstractWe have successfully obtained large lateral grains with well-controlled grain boundary. The proposed excimer laser annealing (ELA) method produces 2-dimensionally controlled grain growth because the temperature gradient is induced in two directions. Along the channel direction, the floating active structure produces large thermal gradient due to very low thermal conductivity of the air-gap. Along the perpendicular direction to the channel, the surface tension effect also produces thermal gradient. The proposed ELA method can control the grain boundary perpendicular and parallel to current path with only one laser irradiation.

Excimer Laser Annealing

ABSTRACTThin silicon films with dendritic large grains can be obtained by Si+ or P+ implantation and subsequent low temperature annealing of the silicon film. We tried further exposing the films with an excimer laser after the grain growth. As a result, improvement of electronic properties such as high carrier mobility or low resistivity were obtained. By TEM observation, polycrystalline grains with a dendritic structure did not melt after laser annealing and it was found that the improvement of electronic properties were achieved mainly due to the improvement of crystallinity by U-V(Ultra-Violet) reflectance, ESR(Electron Spin Resonance) analysis and TFT characteristics. We are convinced that this advanced laser pulse annealing method is an ideal RTA process in the near future and is expected to be applicable to ULSI processes for inter connects, high density stacked SRAM and for large area electronics on glass such as a contact line sensor or LCD(Liquid Crystal Display).
