Silicon Crystal Annealing Furnace from Japan

Rapid thermal annealing equipment for semiconductor crystals uses precisely controlled heating/cooling cycles to relieve stresses in silicon boules post-grinding, preventing wafer cracking. Temperature treatment process per Chapter 84. HTS 8419.89.95 for non-furnace specific semiconductor thermal equipment.

Import Tips

Document ramp rates (e.g

50°C/sec) proving semiconductor-grade thermal control

Avoid 8514 classification by emphasizing process integration over furnace function

Include boule size compatibility (150-450mm) specs
