摘要： By improving profile of impurity concentration in a channel portion of an FET or an IGBT of a trench gate type, variation of threshold value is lessened, and a destruction caused by current concentration is prevented while suppressing deterioration of cut-off characteristics. An island of a base region of p-type is formed in a semiconductor substrate of n-type by carrying out high acceleration ion implantation twice followed by annealing, so that the impurity concentration profile in a channel portion changes gradually in a depth direction. Accordingly, it is possible to lessen variation of the threshold value and to reduce pinch resistance while at the same time improving sub-threshold voltage coefficient and conductance characteristics.

摘要： A semiconductor substrate has a trench for forming a gate insulation film and a gate electrode therein, or an insulated isolation isolating a semiconductor element like a transistor from other elements. The trench is formed by anisotropic dry etching. After that, a shape of the trench is improved so that a bottom portion and an opening portion are rounded or tapered by a wet process using a mixed solution containing hydrofluoric acid and nitric acid. By modifying the shape of the trench, electrical characteristics of the trench are improved. For example, an oxide film formed in the trench has high quality, whereby a gate withstanding voltage is improved.

摘要： A waste treatment furnace includes a first waste treatment chamber with a first burner chamber communicating therewith, and a second waste treatment chamber with a second burner chamber communicating therewith. A common bottom wall is positioned under the first and second waste treatment chambers which is inclined downwardly from the first chamber to the second chamber to facilitate transfer of waste. Each burner chamber includes a burner and a plurality of protuberances disposed across its inner surface. The protuberances effectively reflect heat from the first and second burners so that the heater air in the first and second burner chambers is homogenized.

摘要： A shaft 6 includes a textile layer. The textile layer has a biaxial textile 20 composed of warps and wefts. The warp is oriented substantially parallel to an axial direction of the shaft. The weft is oriented substantially perpendicularly to the axial direction of the shaft. When a tensile elastic modulus of the warp is defined as ET (tf/mm2) and a tensile elastic modulus of the weft is defined as EY (tf/mm2), the tensile elastic modulus ET is smaller than the tensile elastic modulus EY. Preferably, the warp is a PAN carbon fiber and the weft is a pitch carbon fiber. Preferably, when a tensile strength of the warp is defined as ST (kgf/mm2) and a tensile strength of the weft is defined as SY (kgf/mm2), the tensile strength ST is greater than the tensile strength SY.
