    Abstract: An IC (1), with a thick copper induction winding (20) located above a passivation layer (6) and having depending ends (12) connected to contact pads (5), is new. A new monolithic IC (1) has metallic contact pads (5), extending from flush with the upper surface (6) of a passivation layer (4) to an underlying semiconductor substrate layer (2), and an induction coil winding (20) which is located in a plane parallel to the passivation layer upper surface (6) and which consists of copper turns (21, 22, 23, 27, 28) of greater than 10 microns thickness, the winding ends (12) extending below the winding plane for connection to the contact pads (5). An Independent claim is also included for manufacturing a monolithic IC incorporating an inductive component by: (a) depositing a polyimide or benzocyclobutene layer on a semiconductor substrate (2) which is covered with a passivation layer (4) and which has metallic contact pads (5) extending from the passivation layer upper surface (6) to the substrate (2); (b) depositing a silica layer (16) on the polyimide or benzocyclobutene layer; (c) forming openings in the silica and polyimide or benzocyclobutene layers down to the contact pads (5); (d) applying a metal growth layer and a photosensitive resin layer on the structure; (e) exposing and developing the resin to form the lower face of the inductive component; (f) electrodepositing a copper layer on the exposed zones of the metal growth layer to form the inductive component strip; and (g) removing residues of the resin and the metal growth layer.

    Abstract: A magnetic switch includes a substrate having a recess therein. A rotor or rotors are provided on the substrate. The rotor includes a tail portion that overlies the recess, and a head portion that extends on the substrate outside the recess. The rotor may be fabricated from ferromagnetic material, and is configured to rotate the tail in the recess in response to a changed magnetic field. First and second magnetic switch contacts also are provided that are configured to make or break electrical connection between one another in response to rotation of the tail in the recess, in response to the changed magnetic field. Related operation and fabrication methods also are described.

    Abstract: A chip card for analyzing physicochemical properties of a cutaneous surface includes at least one body sensor which can deliver a signal representing a measurement of a physicochemical property of the cutaneous surface, and a processing unit used to treat signals delivered by the body sensor and an optional environment sensor and to then store signals in a storage unit on the card. An electrical energy source on the card provides electrical power to the body sensor and the processing unit.

    Abstract: Lockable microelectromechanical actuators include a microelectromechanical actuator, a thermoplastic material that is coupled to the microelectromechanical actuator to lock the microelectromechanical actuator, and a heater that melts the thermoplastic material to allow movement of the microelectromechanical actuator. When the thermoplastic material solidifies, movement of the microelectromechanical actuator can be locked, without the need to maintain power, in the form of electrical, magnetic and/or electrostatic energy, to the microelectromechanical actuator, and without the need to rely on mechanical friction to hold the microelectromechanical actuator in place. Thus, the thermoplastic material can act as a glue to hold structures in a particular position without the need for continuous power application. Moreover, it has been found unexpectedly, that the thermoplastic material can solidify rapidly enough to lock the microelectromechanical actuator at or near its most recent position.
