    Abstract: A power device (D) integrated on a semiconductor substrate (1) with double thickness of a gate dielectric layer (S) and a corresponding manufacturing method for said power device (D), said method comprising the following steps: forming first dielectric portions (3) having a first thickness; forming on the whole semiconductor substrate (1) a first dielectric layer (4) thinner than the first dielectric portions (3); forming a conductive layer (5) on the first dielectric layer (4); forming a second dielectric layer (6,13) on the conductive layer (5); performing an etching step of the second dielectric layer (6,13) and of the conductive layer (5) to form first spacers (7,14) and a gate electrode (5a), to define, between the gate electrode (5a) and the substrate (1), second dielectric portions (4a) in the first dielectric layer (4), the second dielectric portions (4a) being auto-aligned with the first portions (3). An etching step may be carried out to remove the portion of the conductive layer (5) overlying the thick dielectric portions (3). A body contact trench (12) may be formed using second spacers (11).

    Abstract: A method of filtering and an image filter (10) is disclosed. The filter is provided for a digital camera including image sensors sensitive to light, a color filter placed over sensitive elements of the sensors and patterned according to a Bayer mosaic pattern layout and an interpolation algorithm joining together the digital information provided by differently colored adjacent pixels in said Bayer pattern. The filter (10) is adaptive and includes a noise level computation block (26) for operating directly on a said Bayer pattern data set of for each color channel thus removing noise while simultaneously preserving picture detail.

    CPC classification number: G01C19/5712

    Abstract: Described herein is an integrated microelectromechanical structure (30), provided with: a driving mass (3), anchored to a substrate (2) via elastic anchorage elements (8a, 8b) and moved in a plane (xy) with a driving movement; and a first sensing mass (16a'), suspended inside, and coupled to, the driving mass via elastic supporting elements (20') so as to be fixed with respect to the driving mass (3) in the driving movement and to perform a detection movement of rotation out of the plane (xy) in response to a first angular velocity (© x ); the elastic anchorage elements (8a, 8b) and the elastic supporting elements (20') cause the detection movement to be decoupled from the driving movement. The elastic supporting elements are coupled to the first sensing mass (16a') at an end portion (31; 31') thereof, and the axis of rotation of the detection movement extends, within the first sensing mass, only through the aforesaid end portion.
