摘要： PROBLEM TO BE SOLVED: To provide a semiconductor element exhibiting excellent high speed operability, and to provide its convenient fabricating process.
SOLUTION: The semiconductor element 10 comprises a 6H-SC substrate 11 of hexagonal system, and a 3C-SiC thin film 12 of cubic system wherein a gate oxide film 13 and a gate electrode 14 are provided on the film surface of the thin film 12 and a source 15 and a drain 16 are provided on the left and right of the thin film 12. Energy level of band gap is shifted between the 6H-SiC substrate 11 and the 3C-SiC thin film 12 due to difference of the crystal structure (hexagonal system and cubic system) wherein the conduction band of the substrate 11 is higher than that of the thin film 12 and the valence band of the substrate 11 is also higher than that of the thin film 12. Furthermore, conduction band of the thin film 12 is higher than the valence band of the substrate 11. Based on the characteristics of the band gap, electrons are made to exist in the conduction band of the thin film 12 on the lower energy level side whereas holes are made to exist in the conduction band of the substrate 11 on the higher energy level side.

摘要： PURPOSE:To produce an iron-base sintered alloy for valve seat excellent in wear resistance. CONSTITUTION:A powder mixture is prepared by mixing, by weight ratio, 2-30% of Ni-base alloy powder having a composition consisting of 5-20% Mo, 20-40% Cr, 10-20% W, and the balance Ni with inevitable impurities and 0.2-2% of graphite powder with an iron-base alloy powder having a composition consisting of, by weight ratio, 2-15% Co, 2-10%, preferably >3%-10%, Mo, and the balance Fe with inevitable impurities, which is compacted. Further, 0.2-2% of solid lubricant is mixed with the above, if necessary, and they are compacted. The resulting green compact is sintered at a temp. between 1323K and the melting point of the Ni-base alloy powder. Because alloy powders are used and matrix structure is sintered, the degree of homogenization of entering into solid solution of alloying elements in a matrix is increased and superior corrosion resistance, oxidation resistance, and wear resistance can be obtained with minimal alloy quantity, and further, wear resistance can be improved because Mo, Cr, and W in the Ni-base alloy powder combine with C to form carbides. Moreover, machinability can be improved by adding free cutting agent.
