Abstract:
The reliability of a semiconductor device is improved. A sealing resin (sealed body) is formed between a sub-substrate (first base member) and a base substrate (second base member) that are provided individually and distinctly to be integrated therewith, and then, the sub-substrate is electrically coupled to the second base member. As a means for electrically coupling the sub-substrate to the base substrate, lands (first lands) formed on the sub-substrate and lands (second lands) formed on the base substrate are disposed such that the respective positions thereof are aligned. After through holes are formed from the lands of the sub-substrate toward the lands of the base substrate, a solder member (conductive member) is formed in each of the through holes.
Abstract:
Provided is a substrate for a thin-film photoelectric conversion device which makes it possible to produce the device having improved characteristics at low cost and high productivity. The substrate includes a transparent base member, with a transparent underlying layer and a transparent electrode layer successively stacked on one main surface of the transparent base member. The underlying layer includes transparent insulating fine particles and transparent binder, and the particles are dispersed to cover the one main surface with a coverage factor of particles—ranging from 30% or more to less than 80%. An antireflection layer is provided on the other main surface of the transparent base. The antireflection layer includes transparent insulating fine particles and transparent binder, and the particles are dispersed to cover the other main surface with a coverage factor greater than the underlying layer. The transparent electrode layer contains zinc oxide deposited by low-pressure CVD method.
Abstract:
The reliability of the semiconductor device which has the structure which stores a plurality of semiconductor chips with which plane sizes differ in the same sealing body in the state where they are accumulated via the insulating film which has adhesive property is improved.In the semiconductor device which has the structure which stores a plurality of semiconductor chips with which plane sizes differ in the same sealing body in the state where they are accumulated via DAF, thickness of DAF of the back surface of the uppermost semiconductor chip with which the control circuit was formed was made thicker than each of DAF of the back surface of the lower layer semiconductor chip with which the memory circuit was formed. Hereby, the defect that the bonding wire which connects the uppermost semiconductor chip and a wiring substrate contacts the main surface corner part of a lower layer semiconductor chip can be reduced.

Abstract:
There is provided a system and method for quantitative analysis of a cause of tire trouble capable of quantitatively analyzing whether the tire trouble is caused by the tire itself or in a matter of harshness of a tire using condition in light of not only a force acting on a tire mounted on a running vehicle but also harshness of a tire using condition such as a traveling speed of the vehicle, level difference of a road surface, a curve and gradient information. The method for quantitative analysis of a cause of tire trouble according to the present invention is characterized by comprising the steps of receiving positional data of a running vehicle from the GPS, simultaneously measuring triaxial accelerations which are accelerations acting on the running vehicle in back-and-forward, right-and-left and up-and-down directions while time synchronizing with the received data, quantitatively analyzing harshness of a tire using condition from the received positional data and the triaxial acceleration data, and displaying an analysis result.
