Title: Vapor deposition method
Inventor: HOSHINA JUNICHI
IPC: H01L21/205
Filed: 1990-10-01
Abstract: PURPOSE:To enable crystal growth with no contaminants in the upstream side of an inner tube susceptor by mounting a crystal substrate the same as a growth substrate as the second substrate in the upstream side of the susceptor. CONSTITUTION:A furnace core tube 1 incorporates a susceptor 6 which mounts a first substrate 8 to grow a thin film. To prevent the convection of raw material gas in the furnace core tube 1, convection gas is flowed from a convection gas inlet 4 and exhausted from a gas exhaust 5; further the temperature of the susceptor 6 is raised by heating the furnace core tube 1, and raw material gas is flowed from a raw material gas inlet 3. A second substrate 15 is mounted in the upstream side with respect to the raw material gas stream of the susceptor 6 to grow a thin film by deposition of contaminants in the furnace core tube 1 during thin film growth on the second substrate 15; then, the second substrate 15 is exchanged, and a thin film is grown on the first substrate 8 with the inner tube 2 kept clean. This process allows removal of deposits (contaminants) produced by decomposition of the raw material gas; thereby making crystal growth with no contaminants on the upstream side of the susceptor 6.

Filed: 1987-10-20
Abstract: PURPOSE:To improve the characteristics when superconductive materials are laminated and to improve crystallizability of interface by forming a layer (insulation film between layers) consisting of oxidized yttrium between superconductive material layers of ceramics family. CONSTITUTION:First of all, a superconductive material layer 2 of ceramics family with a composition of YBa2Cu3O7-x is formed on a substrate 1 under a temperature of 300 to 1000 deg.C by the EB deposition method or CVD method and then it is subject to oxygen thermal treatment under a temperature of 400-1000 deg.C within the same chamber. It allows introduction of oxygen to be adjusted properly, thus resulting in a high-temperature superconductor. After that, a Y2O3 layer 4 is formed on the superconductive material layer 2 under a temperature of 300-1000 deg.C within the same chamber by the sputtering method, EB deposition method, or CVD method. Then, the superconductive material layer 3 is formed on a Y2O3 layer using the same process as the process for forming the superconductive material layer 2. Thus, since a layer consisting of oxidized yttrium is formed between ceramics series superconductive material layers, stability and characteristics when superconductive materials are multi- layered are superb. Also, the crystallizability of interface can be improved.
