  • Publication number: 20240186399
    Abstract: Disclosed are HfO2—ZrO2 superlattice heterostructures such as a gate stack (24), stabilized with mixed ferroelectric-antiferroelectric order. directly integrated onto silicon (Si) transistors and scaled down to ˜20 ?. the same gate oxide thickness required for high-performance transistors. The overall equivalent oxide thickness in metal-oxide-semiconductor capacitors is ˜6.5 ? effective SiO2 thickness, which is even smaller than the interfacial SiO2 thickness (8.0-8.5 ?) itself. and the resulting large capacitance cannot be achieved in conventional HfO2-based high-? dielectric gate stacks without scavenging the interfacial SiO2. which has adverse effects on the electron transport and gate leakage current. Accordingly. the disclosed gate stacks (24), which do not require such scavenging.

  • Patent number: 6921926
    Abstract: Light emitting diode (LED) packages are made by first providing a platelike frame having a plurality of cells, each of which is composed of a main plate and a separate arm. Secondly, an LED die and a reflecting ring are respectively mounted on top of each main plate such that the die is located at a center of the reflecting ring. Then a conductive wire is connected between the top surface of the die and a top surface of the separate arm by wire bonding. A domed transparent encapsulant is then molded on each of the cells. The encapsulant encapsulates the die, the reflecting ring and the conductive wire and covers the main plate and the separate arm, and fills a space between the main plate and the separate arm to remain their spaced apart. Finally, the frame is cut according to the size of each cell to obtain the LED packages.
