摘要:
A method for fine processing includes a first step in which a first reaction gas is introduced into a reaction chamber which contains a material to be processed, followed by irradiation with light to form an active layer on the surface of the material through photochemical reaction between the material and the first reaction gas, a second step in which the active layer is selectively irradiated with energy in an atmosphere of a second reaction gas to cause a chemical change only in the irradiated portion to form a latent image layer, a third step in which either the latent image layer or active layer is removed and a fourth step in which, using the portion left unremoved in the third step as a shield mask, the portion other than the masked portion is etched.

摘要:
A matrix circuit has a plurality of blocks each including a plurality of semiconductor unit elements, the semiconductor unit elements of each block being adapted to be impressed with a predetermined voltage at the same time, each unit element becoming active when impressed with the predetermined voltage, and a drive device for impressing the predetermined voltage to the plurality of blocks sequentially. The matrix circuit includes a first selective device for selecting either ground or a desired other than ground voltage, and a second selective device for selecting one of the output of the drive device and the output of the first selective device whereby the output of the second selective device renders active the plurality of unit elements of each block.
摘要:
A photoconductive type sensor which comprises a photoconductive layer having a photosensing region. A pair of main electrodes are provided which are disposed on the photosensing region of the photoconductive layer. The sensor also comprises a gate electrode for applying a bias voltage to the photosensing region. The gate electrode provides a bias of one polarity so as to suppress the generation of a channel in the photosensing region.
摘要:
There is a photosensor comprising: a photoconductive layer containing amorphous silicon provided on a substrate in which this photoconductive layer consists of laminated films of two or more layers having different refractive indexes and the refractive index of the lowest layer of the laminated films is not larger than 3.2 for the incident light of a wavelength of 6328 .ANG.; a pair of electrodes provided in electrical contact with the photoconductive layer; and a photo sensing section. A long size image sensor unit is constituted by a plurality of such photosensors arranged like an array, a matrix drive circuit to matrix-drive each photosensor, and a light source such as light emitting diodes or a fluorescent lamp to illuminate an original to be read. With this image sensor unit, it is possible to provide a low-cost image reading apparatus which can read an image on the original at a high speed in which: the uniformity of the characteristic of each photosensor is improved; a variation in signal between the bits is reduced; a correction circuit for such a variation is unnecessary; and the peel-off of the photoconductive layer does not occur. A method of manufacturing such photosensors is also disclosed.
