  • Publication number: 20230230851
    Abstract: The present disclosure relates to use of 193-nm excimer laser-based lift-off (LLO) of Al0.26Ga0.74N/GaN High-electron mobility transistors (HEMTs) with thick (t>10 ?m) AlN heat spreading buffer layers grown over sapphire substrates. The use of the thick AlN heat spreading layer resulted in thermal resistance (Rth) of 16 Kmm/W for as-fabricated devices on sapphire, which is lower than the value of ?25-50 Kmm/W for standard HEMT structures on sapphire without the heat-spreaders. Soldering the LLO devices onto a copper heat sink led to a further reduction of Rth to 8 Kmm/W, a value comparable to published measurements on bulk SiC substrates. The reduction in Rth by LLO and bonding to copper led to significantly reduced self-heating and drain current droop. A drain current density as high as 0.9 A/mm was observed despite a marginal reduction of the carrier mobility (?1800 to ?1500 cm2/Vs). This is the highest drain current density and mobility reported to-date for LLO AlGaN/GaN HEMTs.

  • Publication number: 20230103072
    Abstract: A 1.8-times improved light extraction efficiency (LEE) is reported under DC test conditions for truncated cone AlGaN DUV micropixel LEDs when the pixel size was reduced from 90 to 5 µm. This is shown to be a direct consequence of the absorption of the TM-polarized photons travelling in a direction parallel to the device epitaxial layers. Presently disclosed cathodoluminescence measurements show the lateral absorption length for 275 nm DUV photons to be 15 µm, which is ~1000 times shorter than that for waveguiding in the A0.65Ga0.35N cladding layers. Results show the re-absorption of this laterally travelling emission by the multiple quantum wells and the p-contact GaN layer to be a key factor limiting the LEE. Hence, for DUV emitters, scaling down to sub-20 µm device dimensions is critical for maximizing LEE. Presently disclosed sub-20 µm AIGaN-based LEDs do not show pronounced edge recombination effects.

  • Patent number: 11513986
    Abstract: To improve data throughput and data transfer rate, a contiguous block of host memory can be allocated for data transfers between the host system and an integrated circuit device such as a peripheral component. By using a contiguous block of memory that acts as a circular buffer, the memory address field of memory descriptors can be eliminated because the host system only need to inform the data movement engine of the length of each data transfer. The data movement engine can maintain pointers to keep track of the memory address in the host memory to read from and write to. After each data transfer, the relevant pointer can be incremented by a value corresponding to the length indicated in the memory descriptor for the transfer. As such, it is not necessary for the host system to provide the data movement engine with the memory address of each transfer.
