Dark Matter in CCDs (DAMIC) has pioneered the detection of nuclear and electronic recoils induced by Dark Matter (DM) particles in charge-coupled devices (CCDs). Scientific CCDs are commonly used in the focal plane of astronomical telescopes for the digital imaging of faint astrophysical objects. Our non-standard use of CCDs was demonstrated at SNOLAB (Sudbury, Canada) where a 40-g prototype detector is currently operating. DAMIC-M is a 1 Kg detector to be installed at Laboratoire Souterrain de Modane (LSM) in France which profits from this experience and, at the same time, will greatly improve in sensitivity by further innovating the detector technology. CCDs show unique properties: a) unprecedented charge resolution, b) low leakage current, c) spatial resolution and 3D reconstruction, d) background identification and rejection.
