  • Patent number: 10840424
    Abstract: Standardized photon building blocks are used to make both discrete light emitters as well as array products. Each photon building block has one or more LED chips mounted on a substrate. No electrical conductors pass between the top and bottom surfaces of the substrate. The photon building blocks are supported by an interconnect structure that is attached to a heat sink. Landing pads on the top surface of the substrate of each photon building block are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self-align within the interconnect structure. Conductors on the interconnect structure are electrically coupled to the LED dice in the photon building blocks through the contact pads and landing pads. The bottom surface of the interconnect structure is coplanar with the bottom surfaces of the substrates of the photon building blocks.

  • Patent number: 10833081
    Abstract: Structures and methods that facilitate forming isolated contacts in stacked vertical transport field effect transistors (VTFETs). A pair of stacked VTFETs are formed on a substrate and isolated from each other. A via or hole is formed to extend to a drain of the second VTFET and a source of the first VTFET. The via is filled with a metal below the first VTFET to form the second contact. The second contact is capped with a non-conductive material and the remaining portion of the via is filled with metal to form the first contact. Alternatively, a via or hole is formed to extend to a source of the second VTFET and a source of the first VTFET. The second contact may serve as a local interconnect, a ground, or a voltage source connection.

  • Patent number: 10818679
    Abstract: In a MONOS memory of the split-gate type formed by a field effect transistor formed on a fin, it is prevented that the rewrite lifetime of the MONOS memory is reduced due to charges being locally transferred into and out of an ONO film in the vicinity of the top of the fin by repeating the write operation and the erase operation. By forming a source region at a position spaced downward from a first upper surface of the fin in a region directly below a memory gate electrode, the current is prevented from flowing concentratedly at the upper end of the fin.

A base material (200) is supported by a frame body (250) so that a second surface (204) of the base material (200) is oriented obliquely upward from the standard direction (S). Thereby, a reference direction (R) is oriented obliquely upward from the standard direction (S). Light from the light-emitting system (20) has standard chromaticity in the standard direction (S). In addition, the light from the light-emitting system (20) has first chromaticity and second chromaticity in a first side direction (S1) and a second side direction (S2), respectively, the first side direction (S1) and the second side direction (S2) being symmetric with respect to the standard direction (S). A difference between the first chromaticity and the standard chromaticity is smaller than a difference between the second chromaticity and the standard chromaticity.
