IPC: H03H9/64
Filed: 1982-07-27
Abstract: PURPOSE:To minimize the loss of a filter, by extending a common bus bar of electrodes adjacent to each other and at the same time crossing the grating of a reflector for elastic display waves and increasing gradually the width of the bus bar in the grating. CONSTITUTION:A common bus bar 7 for inter-digital transducer electrodes 5 and 6 formed on a piezoelectric substrate is extended to cross the gratings of reflectors 8 and 9 provided across the electrodes 5 and 6 with no connection to these gratings. At the same time, the width of the bar 7 is increased gradually in the gratings, and a wire is bonded to the bar 7 for grounding at the part close to both sides of the grating where the width of the bar 7 is large. Thus, the ohmic loss of the bus 7 is minimized, and therefore the filter loss can also be minimized.

Filed: 1980-09-23
Abstract: PURPOSE:To prevent the erroneous operation of alpha-ray emission of an MOSLSI by epitaxially growing a high specific resistance layer of low impurity density on a low resistance Si substrate and electrically isolating the epitaxial layer with a selectively oxidized film reaching the low resistance substrate. CONSTITUTION:A P type epitaxial layer 2 having, for example, 10OMEGAcm is grown in 5mum on a P type substrate 1 having, for example, 0.05OMEGAcm. Then, with Si intrided film as a mask, a field oxidized film 3 is formed by a selective oxidation method. The film 3 is formed in the depth reaching the substrate 1, but when a high density region (channel stopping layer) 4 is formed between the film and the substrate 1, the film 3 may e reduced in thickness. Subsequently, an MOSFET or the like is formed in an ordinary step in the layer 2. In this manner, minority carrier generated in the substrate 1 by alpha-ray emission is mostly recombined in the substrate due to short diffusion length, thereby enabling to eliminate the influence to the element characteristics.

A shot process is applied to the inner circumference of the taper hole 5 to form a minutely uneven face on the abovementioned inner circumference for a chrome plating not to be separated easily. After a degreasing process by e.g. organic solvent such as trichlene is applied to the inner circumference of the taper hole 5, a hard chrome plating layer is formed on the inner circumference. Finally, the surface of the above chrome plating layer is cut in slight thickness to be finished. Thus, the hard chrome plating layer can be formed on only the taper face of the main shaft and the main shaft having superior rigidity and wear resistance can be manufactured.
