Skipper CCD technology has recently unlocked unprecedented sensitivity to ionization signals as faint as a single electron, enabling new frontiers in direct dark matter searches. As a result, the DAMIC-M experiment at the Modane Underground Laboratory, based on Skipper CCDs, has delivered the most stringent constraints to date on sub-MeV dark matter interacting with electrons, probing both freeze-out and freeze-in scenarios in the dark sector for the first time. While Skipper CCDs represent a technological breakthrough by overcoming the readout noise floor of conventional CCDs, they do so at the cost of readout time. New recent improvements, including MAS-CCD, SiSeRO, and CMOS Skipper architectures, combine faster readout with Skipper-level performance. I will detail those and focus on the possibility of designing a future low-noise imager using Skipper CMOS technology.
