Abstract:
Apparatuses for low-temperature heat-treatment of semiconductor films upon thermally susceptible non-conducting substrates comprises:(a) induction coils continuously forming an upper layer and a lower layer in such a way that the electromagnetic force can be generated parallel to the in-plane direction of semiconductor films, wherein heat-treatment materials consisting of thermally susceptible non-conducting substrates and semiconductor films deposited thereon can be moved into the space between said upper layer and said lower layer; (b) magnetic cores covering the external surfaces of said upper layer and said lower layer, respectively; and, (c) preheating member heating the heat-treatment materials for preparation of induction-heat prior to its movement into the space between said upper layer and said lower layer, wherein the semiconductor films of the heat-treatment materials is heated to the extent that said semiconductor films can be induction-heated at the minimum thermal budget acceptable for the use of substrates.
