A conduction-cooled superconducting power transmission cable wherein a High-Temperature Superconducting (HTS) wire is surrounded by an inner layer of thermal insulator, one or more layers of high thermal conductivity material, such as copper, and an outer layer of thermal insulator with cryogenic coolant sources distributed along the power transmission cable and coupled to the copper layers or both the copper layers and the HTS wire. The cryogenic coolant sources can be reservoirs, a distribution system of coolant or stand alone refrigeration systems. He Hor Nliquid coolant can be used. A method for calculating the parameters to maintain the critical temperature of the HTS wire and a method for calculating the cool down time from ambient conditions are disclosed.

A method for curing spin-on-glass formed on a wafer film which insulates the metal layers and flattens any step difference in the process for manufacturing a multi-layered metal layer of a highly integrated semiconductor device which comprises establishing a predetermined initial temperature in a heating chamber with an ultraviolet light source. A wafer, on which a SOG film to be cured is formed, is then introdued into the heated chamber and the temperature gradually increased to a predetermined maximum temperature. The SOG film is irradiated with ultraviolet light at a predetermined wavelength simultaneously with the application of heat at the maximum temperature for a predetermined time. The wafer is then cooled.
