X-RAY DETECTOR AND METHOD OF ITS MANUFACTURING Russian patent published in 2020 - IPC H01L31/203 

FIELD: image-processing device.

SUBSTANCE: disclosed group of inventions relates to the manufacture of image detecting devices. Disclosed X-ray detector comprises a housing and a matrix of photosensitive elements arranged therein, consisting of at least four fragments arranged with gaps relative to each other to form a common photosensitive surface. To manufacture the disclosed detector, a corresponding intermediate element is attached to each of the fragments, which enables to connect the input of each of the X-ray image forming means with the outputs of the corresponding photosensitive elements to form a temporary assembly, installation of each of fragments of the above matrix on the corresponding separate base, supply of vacuum to each of separate bases for fixation of the corresponding fragment. Electric connection of each of contact pads of corresponding fragment and appropriate contact platform of said intermediate element is created. A layer of liquid translucent adhesive material is applied on the corresponding side of the fiber-optic plate. Each of said temporary assemblies is arranged on said layer of translucent adhesive material with gaps relative to each other. Said temporary assemblies are aligned to provide gaps between them of constant width. Vacuum supply to each of said separate bases is terminated and temporarily separated. Said fragments are pressed to said layer of translucent adhesive material, said layer is cured with translucent adhesive. Each of said separate bases is fixed on corresponding fragment of said matrix. An input of each of said X-ray imaging means is connected to outputs of corresponding photosensitive elements. There is a layer of material which converts X-rays into visible light over said matrix, placing the obtained assembly in a housing.

EFFECT: technical result consists in improvement of reliability and durability of detector, high quality of obtained X-ray image, high manufacturability of detector, reduced amount of rejects of finished products.
