  • Patent number: 11949051
    Abstract: A wavelength conversion member includes a substrate, a phosphor layer, and a ventilated blade. The substrate is configured to rotate based on an axis. The phosphor layer is disposed on the substrate. The ventilated blade is disposed on the substrate and has a pore density between 10 ppi and 500 ppi or a volume porosity between 5% and 95%.

  • Publication number: 20240088246
    Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.

  • Publication number: 20240072219
    Abstract: A wavelength conversion member includes a substrate, a phosphor layer, and a non-ventilated blade. The substrate is configured to rotate based on an axis. The phosphor layer is disposed on the substrate. The non-ventilated blade has a roughness between 5 ?m and 1.25 mm, or a specific surface area of the non-ventilated blade exceeds a geometric area of the non-ventilated blade by more than 10%.

  • Publication number: 20130015589
    Abstract: A multi-die semiconductor device is disclosed. The device may include one or more first-sized die on a substrate and one or more second-sized die affixed over the one or more first-sized die. The second-sized die may have a larger footprint than the first-sized die. An internal molding compound may be provided on the substrate having a footprint the same size as the second-sized die. The second-sized die may be supported on the internal molding compound. Thereafter, the first and second-sized die and the internal molding compound may be encapsulated in an external molding compound.
