Φ-factory DAΦNE at the INFN Laboratori Nazionali di Frascati (LNF), has started in mid 2011. KLOE-2 is the first experiment using the GEM technology with a cylindrical geometry, developed at LNF by the Inner Tracker group and within the RD51 Collaboration as one of the key activities. Three layers of the Inner Tracker have been completed and the construction of the fourth and last layer has started. The production's procedure will be reported together with the first results obtained with 5.9 keV X-rays and cosmic-ray muons collected at LNF Inner Tracker test stand.
