  • Patent number: 10403577
    Abstract: Dielets on flexible and stretchable packaging for microelectronics are provided. Configurations of flexible, stretchable, and twistable microelectronic packages are achieved by rendering chip layouts, including processors and memories, in distributed collections of dielets implemented on flexible and/or stretchable media. High-density communication between the dielets is achieved with various direct-bonding or hybrid bonding techniques that achieve high conductor count and very fine pitch on flexible substrates. An example process uses high-density interconnects direct-bonded or hybrid bonded between standard interfaces of dielets to create a flexible microelectronics package. In another example, a process uses high-density interconnections direct-bonded between native interconnects of the dielets to create the flexible microelectronics packages, without the standard interfaces.

  • Patent number: 10381599
    Abstract: A highly reliable light-emitting device is provided. Damage to an element due to externally applied physical power is suppressed. Alternatively, in a process of pressure-bonding of an FPC, damage to a resin and a wiring which are in contact with a flexible substrate due to heat is suppressed. A neutral plane at which stress-strain is not generated when a flexible light-emitting device including an organic EL element is deformed, is positioned in the vicinity of a transistor and the organic EL element. Alternatively, the hardness of the outermost surface of a light-emitting device is high. Alternatively, a substrate having a coefficient of thermal expansion of 10 ppm/K or lower is used as a substrate that overlaps with a terminal portion connected to an FPC.
