Abstract: A method for the serial personalization of smart cards in a production chain includes a phase of detecting a smart card already personalized and physically defective, and a phase of retrieving a serial number of the physically defective smart card, to be assigned to a smart card not yet personalized in the production chain. The physically defective smart card and the smart card not yet personalized are loaded together in the production chain wherein the physically defective smart card is rendered unusable, and the not yet personalized smart card receives the serial number retrieved from the physically defective smart card.

Abstract: A MEMS piezoelectric device includes a monolithic semiconductor body having first and second main surfaces extending parallel to a horizontal plane formed by first and second horizontal axes. A housing cavity is arranged within the monolithic semiconductor body. A membrane is suspended above the housing cavity at the first main surface. A piezoelectric material layer is arranged above a first surface of the membrane with a proof mass coupled to a second surface, opposite to the first surface, along the vertical axis. An electrode arrangement is provided in contact with the piezoelectric material layer. The proof mass causes deformation of the piezoelectric material layer in response to environmental mechanical vibrations. The proof mass is coupled to the membrane by a connection element arranged, in a central position, between the membrane and the proof mass in the direction of the vertical axis.

Abstract: A photodiode structure is based on the use of a double junction sensitive to different wavelength bands based on a magnitude of a reverse bias applied to the photodiode. The monolithic integration of a sensor with double functionality in a single chip allows realization of a low cost ultra-compact sensing element in a single packaging useful in many applications which require simultaneous or spatially synchronized detection of optical photons in different spectral regions.
