Methods and apparatus for detecting a failed temperature sensor within a data storage device and for mitigating the loss of the sensor are provided. One such data storage device includes a non-volatile memory (NVM), a set of temperature sensors, and a processor coupled to the NVM and the temperature sensors. The processor is configured to detect failure of one of the temperature sensors and obtain temperature data from the other temperature sensors. The processor is further configured to estimate, based on the obtained temperature data, the temperature at the failed sensor, and then control at least one function of the data storage device based on the estimated temperature, such as controlling entry into a Read Only mode. In some examples, the processor estimates the temperature at the failed sensor or at various virtual sensor locations using pre-determined formulas having offsets and coefficients determined during an initial machine learning calibration procedure.

Provided are gas distribution apparatus with a showerhead having a front plate and a back plate spaced to form a gas volume, the front plate having an inner surface adjacent the gas volume and an outer surface with a plurality of apertures extending therethrough, the gas volume having a center region and an outer region; a first inlet in fluid communication with the center region of the gas volume, the inlet having an inside and an outside; and a mixer disposed on the inside of the inlet to increase gas flow temperature. Also provided are processing chamber apparatus and methods of depositing a film.
