  • Publication number: 20220382168
    Abstract: In a method of manufacturing a semiconductor device, in an EUV scanner, an EUV lithography operation using an EUV mask is performed on a photo resist layer formed over a semiconductor substrate. After the EUV lithography operation, the EUV mask is unloaded from a mask stage of the EUV scanner. The EUV mask is placed under a reduced pressure below an atmospheric pressure. The EUV mask is heated under the reduced pressure at a first temperature in a range from 100° C. to 350 C°. After the heating, the EUV mask is stored in a mask stocker.

  • Patent number: 10721617
    Abstract: To facilitate LWA PDCP setting/scheduling, a method of providing dynamic PDCP status report polling is proposed. To enhance scheduling efficiency, the transmitter (can be eNB from DL or UE for UL) can dynamically poll PDCP status report for LWA behavior. The polling can be done by a standalone PDCP control PDU or use reserved bit in PDCP data PDU. The triggering condition for PDCP status polling includes: PDCP without poll time exceeds a first threshold, PDCP without poll bytes exceeds a second threshold, PDCP without poll PDU numbers exceeds a third threshold, a data buffer is empty, and when LWA is deactivated.
