An optical blocking region formed with patterned metal reduces light reflection toward pixel sensors in a pixel sensor array. The optical blocking region may be formed of a metal nanoscale grid in order to reflect more light away from the pixel sensors. The optical blocking region may include a dielectric layer, supporting the patterned metal, with high absorption structures or shallow deep trench isolation structures in order to increase absorption and thus reduce light reflection toward the pixel sensors.

The motor including a stator provided with a wave winding coil using a flat conductor and a stator core, and a rotor provided with a rotor shaft is configured such that the wave winding coil includes the cage coil formed of a first wave winding wire assembly wound in plural turns, this assembly being formed of a plurality of bent-end wave winding conductor wires formed in a meandering pattern and overlapped in sequence with displacements from each other, a coil end part of the cage coil at one end is bent toward the rotor with respect to in-slot portions of the stator core, and the coil end part at the one end is positioned closer to an axis of the rotor than an inner peripheral surface of the stator core is.

A predetermined part of one conductive wire is pressurized and plastically worked to form a slot portion having a desired cross section, a part separated from the slot portion by a predetermined dimension is pressed to form a top portion, and then a part separated from the top portion by a predetermined dimension is plastically worked to form the next slot portion. Through repetition of such steps, a conductive wire in which necessary numbers of slot portions and top portions are formed is manufactured. Using the top portion as a reference, the conductive wire is folded to form a coil end portion and is wound by a plurality of turns into a hexagonal shape, thereby forming a hexagonal coil in which the conductive wire is wound by a predetermined number of turns. In the hexagonal coil, bundles of the slot portions become two opposite sides and are inserted in the slots of the armature.

A method for shaping a one- or multi-part wave winding which is intended for insertion into a rotor, a stator or an insertion tool and consists of one or more conductor wires in a magazine is disclosed. The method includes introducing the wave winding, by means of straight portions of the conductor wires, into receptacles of the magazine; pressing the wave winding into the receptacles of the magazine, as a result of which shaping of the conductor wires is brought about and the conductor wires are molded to the receptacles; and them transferring the wave winding with the shaped conductor wires to an insertion tool, a stator, or a rotor. A wave winding, is produced according to the method, in which the straight wire portions have a cross section which is adapted to the groove.
