Abstract
An electronic chip device includes an interface support film having a support film and at least one flat conductive interface placed on the support film, as well as a microcircuit connected to the interface. The interface support film possesses such properties that it can be creased or folded on itself without deterioration. The support film possesses a thickness of less than 75 μm, the best results being obtained with a thickness of between 10 μm and 30 μm. Preferably the support film is selected from among polypropylene (PP), polyethylene (PE), polyethylene teraphtalate (PET). In one embodiment, the device includes a compensation film placed on the support film. The compensation film has a recess containing the microcircuit and its connections. The recess can contain a material to encapsulate the microcircuit and its connections.
