Abstract: PURPOSE:To obtain an extremely dense piezoelectric porcelain by adding organic binder, plasticizer, and solvent defined in compositions to piezoelectric powder to form slurry state, drying and solidifying it, while pressurizing a plurality of sheets formed under specified pressing pressure, and then sintering. CONSTITUTION:2.5-10% of organic binder such as polyvinyl acetate or polyvinyl butyral or the like is added to 100 parts of finely pulverized piezoelectric powder. Then, plasticizer such as dibutylphalate or dioctylphthalate or the like of 70-150% is added to the organic binder, and solvent such as methanol or ethyl acetate or the like is added in 15-30% to the piezoelectric powder, and the mixture is sufficiently mixed. Thereafter, slurry 1 thus obtained is flowed on a flat carrier 2, and is rolled with a blade 3 to form a sheet 4. The sheet 4 is dried, solidified, and separated to be cut in prescribed shape. Subsequently, a plurality of such sheets are superimposed, laminated and pressed under a pressure of 100-1,000kg/cm<2>, and is finally cut in a desired shape, and is then sintered.

Filed: 1986-05-12
Abstract: PURPOSE:To supply each internal load circuit with respectively uniform voltage only by varying and adjusting the design of a wiring pattern in a master slice type semiconductor device by making the positions of respective through-hole section to each first conductive layer differ in the cross direction of a second conductive layer. CONSTITUTION:Substantial wiring length positioned at positions nearer to both sides is made shorter than a first conductive layer 7a at a central position in succession in the substantial wiring length of each first conductive layer 7b-7i reaching respective through-hole 6a-6i from several internal load circuit 1a-1i, thus reducing wiring resistance, etc only by shortened sections. Consequently, the difference of resistance due to the difference of the positions of disposal of each through-hole 11b-11i in the longitudinal direction of second conductive layers can be compensated by the reduction section of wiring resistance in the first conductive layer 7a, thus equalizing wiring resistance up to the whole internal load circuits. Accordingly, the fluctuation of minimum voltage fed to respective internal load circuit 1a-1i from a constant-voltage generation circuit 9 can be prevented, thus constituting a semiconductor device having excellent electrical characteristics.
