摘要:
A semiconductor chip 2 is disposed within a device hole as formed in a tape base material 1a of a tape carrier 1, which chip is smaller in thickness than the tape base material 1a, and then sealing is performed using a seal resin 3 to permit both the principal surface and back surface of such semiconductor chip 2 to be coated therewith. And, the position of the semiconductor chip 2 in a direction along the thickness of the tape base 1a is set to correspond to a stress neutral plane of the TCP as a whole.

Described herein is a stacked package according to the present invention, wherein a plurality of tape carriers which seal semiconductor chips, are multilayered in upward and downward directions. In the stacked package, one ends of leads formed over the whole surfaces of each tape carrier are electrically connected to their corresponding connecting terminals of the semiconductor chip. Other ends of the leads are electrically connected to their corresponding through holes defined in the tape carrier. Connecting terminals common to the plurality of semiconductor chips are formed at the same places of the plurality of tape carriers and withdrawn to the same external connecting terminals through a plurality of mutually-penetrated through holes.

The semiconductor wafer is made thin without any cracks and warp under good workability. The semiconductor wafer thinning process includes the first step of preparing a carrier 1 formed of a base 1a and a suction pad 1b provided on one surface of the base 1a or formed of a base film with an adhesive, the second step of bonding a semiconductor wafer to the carrier 1 in such a manner that a rear surface of the semiconductor wafer 2 with no circuit elements formed therein is opposite to the carrier to form a wafer composite 10, and the third step of holding the carrier of the wafer composite 10 with its semiconductor wafer 2 side up and spin-coating an etchant on the rear surface of the semiconductor wafer 2 thereby to make the semiconductor wafer 2 thin.

An image forming apparatus has an image forming unit for forming an image on a recording material and a fixing unit for fixing the image to the recording material by nipping and conveying the recording material, the fixing unit including a heater which does not generate heat during a standby period in which a printing operation can be started. The heater generates heat for a predetermined period after the start of power supply to the apparatus and then the apparatus is rendered capable of the printing operation.

An antiskid braking device for a motorcycle includes a single pump unit which is used to repressurize braking mechanisms of front and rear wheels of the motorcycle and mounted almost in a central portion of a body frame of the motorcycle and a master cylinder of the front wheel. Middle portions of front wheel brake pipes connecting the pump unit to the braking mechanisms are formed of metallic pipes, both ends of the metallic pipes are connected to the braking mechanisms, the master cylinder and the pump unit through flexible brake hoses, and the metallic pipes are arranged along an inside face of a pair of bilateral tank rails of the body frame extending rearward from a head pipe of the motorcycle. The pump unit is mounted so as to extend in a longitudinal dimension thereof along a longitudinal direction of the motorcycle and a brake pipe port section faces front and rear directions of the body of the motorcycle.
摘要:
A plate replacing apparatus for a printing press having plate lockup devices for fixing the two ends of a plate located in a gap of the circumferential surface of a plate cylinder and wound around the circumferential surface includes an old plate holding mechanism and a new plate holding mechanism. The old plate holding mechanism receives and holds an old plate removed upon release of the plate lockup devices and pivotal movement of the plate cylinder. The new plate holding mechanism removes the old plate and feeds a new plate to the plate cylinder.
