摘要： There is formed on a semiconductor substrate a lamination of a first insulating film of nondoped silicon glass or the like and, on this first insulating film, a second insulating film of boron phosphor silicate glass or the like, with a conductor layer between the two insulating films. A hole is first dry-etched in the second insulating film, leaving the substrate surface covered by the first insulating film. Then the second insulating film is heated to a reflow temperature such that the hole is thermally deformed, flaring as it extends away from the insulating film. Then a second hole is dry-etched in the first insulating film through the first recited hole in the second insulating film, with the consequent exposure of the semiconductor surface. Then a contract electrode is fabricated by filling the first and the second hole with an electroconductive material into direct contact with the substrate surface. Being covered by the first insulating film, the substrate surface is not to be contaminated with impurities during the heating of the second insulating film.

摘要： The operation of a HEMT is monitored on an on-chip basis without increasing the power consumption rate. In a semiconductor device 10, an electron supply layer 12 is formed on a channel layer 11. A two-dimensional electron gas (2DEG) layer 13 is formed at the side of the channel layer of the hetero-junction interface. Electrons flow through the 2DEG layer 13 between a source electrode 14 formed on the surface of the electron supply layer 12 and a drain electrode 15 that is formed on the same surface. A potential detection electrode 17 is arranged on the electron supply layer 12 between the gate electrode 16 and the source electrode 14. A resistor 18 having a sufficiently high resistance value makes the electric current flowing to the potential detection electrode 17 negligible relative to the drain current in operation.

摘要： The file storage system of the present invention comprises a first server including a first file system (FS), and a second server including a second FS. The first and second servers respectively store first and second difference management tables. Upon receiving a write request, the first server stores a difference of a first file in the first FS, updates the first difference management table, and sends, to the second server, a difference storage notification showing that the difference of the first file has been stored in the first FS. The second server receives the difference storage notification, and updates the second difference management table.
