  • Patent number: 5349234
    Abstract: Apparatus and a method for the packaging of semiconductor chips to simplify assembly while improving thermal dissipation from the chip and reducing stress in the chip due to differential thermal expansion between the chip and its package as they are cycled over a temperature range are disclosed. An adhesive tape covers an active area of the chip and leaving bonding pads on the chip exposed through a recess in the adhesive tape. A body with a similar recess supports the other side of the tape. Wire bonds are made in the recess to connect bonding pads on the body to the chip. A lid covers the recess to protect the wire bonds.

  • Patent number: 4617556
    Abstract: A simplified and efficient sound generating device consisting of a self-contained audible signaling device and a means of affording said device protection against moisture and cold temperatures, comprised of a photoelectric cell, a source of energy, a sound transducer means, and appropriate container that permits the entry of light therein. When positioned in an appropriate darkened enclosure, the device permits an immediate audible signal upon the opening of said enclosure and the introduction of light therein. Said device is particularly suited for use as an aid to behavior modification programs that are associated with the need to eliminate the habitual and compulsive over-consumption of food from the diet.
