WHAT IS LASER ANNEALING?
WHAT IS LASER ANNEALING?
Laser annealing enables precise heat treatment exclusively on the surface of wafers or glass substrates, allowing for selective surface modification processes such as crystallization, alloying, and activation. Among various technologies, the line-beam excimer laser annealing system developed by JSW Aktina stands out for its ability to perform uniform annealing over a wide area. This system has also been widely adopted in the mass production of semiconductor and FPD devices.
Crystallization process
  • Non-crystalline state:Amorphous (a-Si)

    The dark gray spheres indicate silicon atoms, while the white spheres represent hydrogen. In the initial amorphous state, atoms are arranged in a random, disordered structure.

  • Laser Annealing Process
  • Crystalline state:Polysilicon (Poly-Si)

    Through the laser annealing process, the atoms align themselves regularly and transform into a crystalline state.
