A semiconductor device having a capacitor formed in a multilayer wiring structure, the semiconductor device comprising a multilayer wiring structure including a plurality of wiring layers formed on a substrate, a capacitor arranged in a predetermined wiring layer in the multilayer wiring structure and having a lower electrode, a dielectric film, and an upper electrode, a first via formed in the predetermined wiring layer and connected to a top surface of the upper electrode of the capacitor, and a second via formed in an overlying wiring layer stacked on the predetermined wiring layer, the second via being formed on the first via.

Semiconductor device having capacitor formed in multilayer wiring structure

A semiconductor apparatus is provided that includes a radiator for efficiently radiating heat generated in a wiring layer used in a surge current path of an electrostatic discharge protection circuit, and also for protecting the wiring layer itself used as the surge current path. The semiconductor apparatus includes an input protection circuit coupled to a wiring provided between an external terminal and an internal circuit, the input protection circuit includes a protection element for protecting the internal circuit from an excessive electrostatic surge input supplied to the external terminal. The semiconductor apparatus further includes a first metal wiring layer coupled to the input protection circuit and included in a current path for the surge electrostatic surge input, and a radiator including a sufficient thermal conductivity material coupled to the first metal wiring layer.

Semiconductor apparatus including a radiator for diffusing the heat generated therein

An oil pump attachment structure is provided for an engine. The oil pump attachment structure includes an oil pump,coaxially driven by the crankshaft,A pump housing,of the pump,is disposed between a front cover,for covering timing chains,and crank sprockets,while leaving a clearance against the front cover,The pump housing,is also fastened to a cylinder block,so as to straddle the timing chains,, through stays,by bolts,With this arrangement, pulsation produced during the operation of the oil pump,is not transmitted to the front cover,directly, so that noise radiated from a front face of the front cover,can be reduced.

Oil pump attachment structure for engine

An oil filter unit comprising a housing (4) and a filter element (14) accommodated therein is fitted to an engine (1) via a bracket (3) having a cylindrical holder (5). The housing (4) is secured to the holder (5) by screwing a male screw (19) on its outer circumference to a female screw (17) formed in the inner circumference of the holder (5). A first cut-out (24) is formed across the female screw (17) and a second cut-out (23) is formed across the male screw (19). When these cut-outs (24, 23) meet together, they form a drain passage which drains the oil in the housing (4) to outside. With this construction, the oil in the housing is drained via a predetermined path and prevented from scattering around, when the filter unit is removed from the engine (1).

Oil filter fixing structure

A mask for evaluation of an aligner includes, on a transparent substrate, a plurality of resistance measurement pattern blocks each including a plurality of resistance measurement patterns which have shapes identical to each other. Resistance values of respective measurement patterns of conductive film portions on a substrate exposed and formed by using a mask having a plurality of the same measurement patterns vary in dependency upon the accuracy of a lens, etc. of the aligner. Accordingly, this evaluation mask is used to carry out exposure process to etch a conductive film to measure resistance values of the conductive film portions to compare them to each other, thereby making it possible to carry evaluation of an aligner including evaluation of a lens therefor.
