摘要： A process for the fabrication of devices that integrate protected microstructures, comprising the following steps: forming, in a body of semiconductor material, at least one microstructure having at least one first portion and one second portion which are relatively mobile with respect to one another and are separated from one another by at least one gap region, which is accessible through a face of the body; and sealing the gap. The sealing step includes depositing on the face of the body a layer of protective material, in such a way as to close the gap region, the protective layer being such as to enable relative motion between the first portion and the second portion of the microstructure.

摘要： A read/write assembly for magnetic hard disks includes at least: one supporting element; one read/write (R/W) transducer; one micro-actuator, set between the R/W transducer and the supporting element; one electrical-connection structure for connection to a remote device carried by the supporting element and connected to the R/W transducer and to the micro-actuator. In addition, a protective structure, set so as to cover the micro-actuator is made of a single piece with the electrical-connection structure.

摘要： Described herein is a read/write transducer for a hard disk drivewith dual actuation stage, comprising at least one hard disk and at least one suspension carrying the read/write transducer. The read/write transducer comprises a supporting body having a substantially parallelepipedal shape, a read/write head arranged on a front face of the supporting body, and a grating defined on one of the side faces of the supporting body during the process of manufacture of the read/write transducer. The grating enables measurement of the position of the read/write transducer with respect to the corresponding suspension in an optical way using a laser transmitter emitting and directing towards the grating a laser beam, and a laser receiver arranged to intercept the laser beam reflected by the grating and outputting a position signal on the basis of which it is possible to calculate, in a simple way, the position of the read/write transducer with respect to the corresponding suspension.
