  • Publication number: 20210249088
    Abstract: Methods, systems, and media for decoding data are described. A sequence of read-level voltages for decoding operations may be determined based on a trend of decoding success indicators, including a first decoding success indicator and a second decoding success indicator. The first decoding success indicator is obtained from a more recent successful decoding operation. The first one of the sequence may be set to a read-level voltage of the first decoding success indicator. If the read-level voltage of the first decoding success indicator is less than a read-level voltage of the second decoding success indicator, then the trend is decreasing, and the second one of the sequence may be set to a read-level voltage less than that of the first one of the sequence. After executing one or more decoding operations, the decoding success indicators may be updated based on the read-level voltage of the current successful decoding operation.

  • Publication number: 20210233802
    Abstract: Methods and apparatus for cleaving a substrate in a semiconductor chamber. The semiconductor chamber pressure is adjusted to a process pressure, a substrate is then heated to a nucleation temperature of ions implanted in the substrate, the temperature of the substrate is then adjusted below the nucleation temperature of the ions, and the temperature is maintained until cleaving of the substrate occurs. Microwaves may be used to provide heating of the substrate for the processes. A cleaving sensor may be used for detection of successful cleaving by detecting pressure changes, acoustic emissions, changes within the substrate, and/or residual gases given off by the implanted ions when the cleaving occurs.
