Abstract:
High density MOS technology power device structure, comprising body regions (31A-31D) of a first conductivity type formed in a semiconductor layer (1) of a second conductivity type, characterized in that said body regions comprise at least one plurality of substantially rectilinear and substantially parallel body stripes (32) each joined at its ends to adjacent body stripes (32) by means of junction regions (33), so that said at least one plurality of body stripes (32) and said junction regions (33) form a continuous, serpentine-shaped body region (31A-31D).
Abstract:
A method of fabricating a MOS transistor with a controllable and modulatable conduction path through a dielectric gate oxide is disclosed, wherein the transistor structure comprises a dielectric oxide layer (3) formed between two silicon plates (1,2), and wherein the silicon plates (1,2) overhang the oxide layer (3) all around to define an undercut (5) having a substantially rectangular cross-sectional shape. The method comprises the steps of: chemically altering the surfaces of the silicon plates (1,2) to have different functional groups (6,7) provided in the undercut (5) from those in the remainder of the surfaces; and selectively reacting the functional groups (6,7) provided in the undercut (5) with an organic molecule (8) having a reversibly reducible center and a molecular length substantially equal to the width of the undercut (5), thereby to establish a covalent bond to each end of the organic molecule (8).
Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling a highly reliable pedometer based on the use of an inertia sensor and a pedometer for executing the method. SOLUTION: A method for controlling a pedometer includes the steps of: generating a signal (Az) correlated to the movement of a user of the pedometer; and detecting the walking steps of the user (200-225, 300-320) on the basis of the signal (Az). The method moreover envisages the steps of checking whether sequences of detected walking steps (K-2, K-1, K) satisfy the predetermined conditions of regularity (230, 320, 345); updating a total number of valid walking steps (N VT , 265, 325, 350) when the conditions of regularity (230, 320, 345) are satisfied; and preventing the updating of the total number of valid walking steps (N VT ) when the conditions of regularity (230, 320, 345) are not satisfied.
