摘要:
A solid-state imager is disclosed wherein isolation regions (4) are covered with power supply lines (8), a light-transmitting lens film (24) whose surface forms continuous convex portions above the isolation regions (4) convex towards channel regions (5) is provided, and a light-transmitting material having a refractive index lower than that of the lens film (24) is provided over the lens film (24).

The present invention intends to provide a manufacturing method of a heat resistant micro-lens. The manufacturing method includes forming on a substrate an inorganic film having the optical transparency; forming, at positions that are on the inorganic film and correspond to lens formation positions, a resist films; etching a portion where the resist films are not formed of the inorganic film; removing the resist films that remain; and irradiating inert gas ions to the inorganic film from which the resist films are removed and that is patterned according to the etching.
摘要:
The flatness of the surface of the light-receiving portion must be increased when the upper structural layer of a light detector is etched. The present invention provides a method for manufacturing an integrated circuit in which an aperture is formed in a stack in which an underlayer, a light-receiving area pad, and an upper structural layer are layered on a substrate, the method comprising a light-receiving area pad etching step for etching the structural layer and the light-receiving area pad under etching conditions in which a high selectivity ratio is maintained between the upper structural layer and the light-receiving area pad; and an underlayer etching step for switching to etching conditions in which the light-receiving area pad has a high selectivity ratio in relation to the underlayer following the light-receiving area pad etching step, and etching the light-receiving area pad and the underlayer. The bottom surface of the aperture can thereby be made flatter and the amount of incident light in the plane of the light-receiving portion can be made more uniform.

A recording and reproducing apparatus has a communicating unit, a reading unit, a storing unit, a control unit, and an output unit. The communicating unit transmits and receives data to/from an information center in which a plurality of additional information have been stored. The reading unit reads out recorded data from a recording medium on which a plurality of data and index data of a plurality of data have been recorded. The data read out from the recording medium by the reading unit is stored in the storing unit. The control unit reads out the additional information corresponding to the recording medium from which the data is read out by the reading unit from the information center by the communicating unit and writes the read-out additional information into the storing unit as additional data of the recording medium which is read out by the reading unit. The output unit outputs the data stored in the storing unit and the additional data.

A floating chassis support mechanism is provided which can thin a disc reproduction apparatus. In the floating chassis support mechanism for a disc reproduction apparatus for supporting a floating chassis with springs and dampers vertically from the opposite side of a loaded disc, the damper is disposed outside of a projection area of the disc, and an area of the floating chassis supported by the dampers is retracted towards the disc side more than a lower surface of the disc.

A thread cutting device for a sewing machine includes a stationary blade which is disposed downwardly of a needle plate and a movable blade. The stationary blade is provided at its one end with a cutting edge. The movable blade which is formed with a cutout in the surface opposite to the stationary blade, is adapted to rotate about a shaft and pass over the needle plate and the stationary blade. The cutout is adapted to catch and guide a thread along a path for the thread and provided with a cutting edge to cooperate with the cutting edge of the stationary blade to cut the thread. A through hole is formed between the cutout and the cutting edge of the movable blade to meander the thread through the hole.

A bi-directional capacitor microphone is formed of first and second transducer sections, each section comprising a diaphragm and a back plate facing the diaphragm and separated therefrom. The diaphragm of the first transducer section includes an electret and the back plate of the second transducer section includes another electret. The back plates of the first and second transducer sections are disposed in a back-to-back configuration and are electrically coupled to each other and to one output. The diaphragms of the first and second transducer sections are connected to each other and to another output, so that an output signal appears between the outputs. Preferably, both electrets are selected to have a negative polarity. The bi-directional microphone so constructed exhibits superior response for lower audio frequencies.
