摘要： Electrode pads are formed on a tape circuit to correspond to positions of solder bumps on an IC. A plurality of pins formed on a periphery of the tape circuit provide electrical connection between the tape circuit and a mother socket. An elastomer sheet is provided between a portion of the tape circuit, on which the electrode pads are formed and the IC is mounted, and the mother socket, and a side surface of the sheet, which contacts with the tape circuit, is formed with cut grooves in lattice fashion such that respective centers of the electrode pads substantially coincide with intersections of the grooves. Thus portions defined by the grooves on the sheet are made independent from one another to enable accommodating pushing forces from the solder bumps, so that, even if dispersion in height generates between the solder bumps, the respective portions defined by the grooves are hardly influenced by one another, and so accommodate the pushing forces from the solder bumps to permit the solder bumps and the electrode pads to surely contact with each other.

摘要： A method for measuring an adhesion strength of a resin material which is capable of accurately and readily measuring a universal adhesion strength independent of dimensions and shapes of specimen. A delamination portion is partially formed between a resin and an adherend material. Loads in two different directions are applied to an adhering interface such that opposed shear stresses are generated. As a result, a true adhering strength can be obtained from an apparent delamination propagating strength in each case.

摘要： In a semiconductor device in which a plurality of semiconductor chips are stacked, performance is enhanced without deteriorating productivity. The semiconductor device has a plurality of elements, an interlayer insulating film, a pad, and a bump electrode electrically connected with the pad sequentially formed on a main surface of a silicon substrate and has a back-surface electrode formed on a back surface of the silicon substrate and electrically connected with the bump electrode. The bump electrode has a protruding portion penetrating through the pad and protruding toward the silicon substrate side. The back-surface electrode is formed so as to reach the protruding portion of the bump electrode from the back surface side of the silicon substrate toward the main surface side and to cover the inside of a back-surface electrode hole portion which does not reach the pad, so that the back-surface electrode is electrically connected with the bump electrode.

摘要： When a through-hole electrode and a rear-surface wire are formed on a rear surface of a chip, a convex portion is formed on the rear surface of the chip due to a rear-surface wiring pad which is a part of the through-hole electrode and the rear-surface wire. This causes the air leakage when the chip is sucked, and therefore, the reduction of the sucking force of the chip occurs. A concave portion is formed in advance in a region where a rear-surface wiring pad and a rear-surface wire are formed. The rear-surface wiring pad and the rear-surface wire are provided inside the concave portion. Thus, a flatness of the rear surface of the chip is ensured by a convex portion caused by thicknesses of the rear-surface wiring pad and the rear-surface wire, so that the reduction of the sucking force does not occur when the chip is handled.
