  The surface array of IceCube, IceTop, operates primarily as a cosmic-ray
detector, as well as a veto for astrophysical neutrino searches for the IceCube
in-ice instrumentation. However, the snow accumulation on top of the IceTop
detectors increases the detection threshold and attenuates the measured IceTop
signals. Enhancing IceTop by a hybrid array of scintillation detectors and
radio antennas will lower the energy threshold for air-shower measurements,
provide more efficient veto capabilities, enable more accurate cosmic-ray
measurements, and improve the detector calibration by compensating for snow
accumulation. After the initial commissioning period, a prototype station at
the South Pole has been recording air-shower data and has successfully observed
coincident events of both the scintillation detectors and the radio antennas
with the IceTop array. The production and calibration of the detectors for the
full planned array has been ongoing. Additionally, one station each has been
installed at the Pierre Auger Observatory and the Telescope Array for further
R\&D of these detectors in different environmental conditions. This
contribution will present the status and future plans of the hybrid detector
stations for the IceCube Surface Array Enhancement.
