Abstract: This application provides a hard disk format conversion method and apparatus, and a storage device, and belongs to the field of storage technologies. In this application, a storage format of a storage unit is converted from an SMR format to a PMR format. Because IOPS in the PMR format is higher than IOPS in the SMR format, IOPS in the storage unit can be increased after the storage format is converted. Alternatively, a storage format of a storage unit is converted from the PMR format to the SMR format. Because a storage capacity in the SMR format is higher than a storage capacity in the PMR format, a storage capacity of the storage unit can be increased after the storage format is converted.

Abstract: Embodiments described herein relate to methods of tuning within semiconductor processes to improve plasma stability. In these embodiments, multiple matching networks are provided. Each of the matching networks couple a radio frequency (RF) source to one of multiple connection points located on an electrode. Based on tuning parameter information and physical geometry information, a controller determines a tuning sequence for the multiple matching networks. As such, some of the matching networks are tuned while the other matching networks are locked. Using multiple matching networks leads to a more uniform plasma within the process volume of the process chamber. Improved plasma uniformity leads to less substrate defects and better device performance. Additionally, in these embodiments, the ability to tune each of the matching networks in a sequence decreases or prevents interference from occurring between the matching networks.
