Embodiment Construction

[0034] In general, the invention relates to an image detector comprising a sensor comprising: a set of pixels arranged in rows and columns in a matrix; a row addressing block; a column reading block; linking rows of pixels to row addressing the row conductors of the blocks; and the column conductors linking the columns of pixels to the column readout blocks. It should be noted that in the context of this patent application the concepts column and row have only a relative meaning, a row of pixels and a column of pixels being nothing but rows of pixels arranged eg at right angles to each other. Row conductors and column conductors are defined to be oriented parallel to the rows of pixels and the columns of pixels, respectively.

[0035] Figure 1arepresents a conventional image detector 10 . The image probe 10 comprises a sensor 11 produced on a first monolithic substrate 12 . The first monolithic substrate 12 comprises sets of pixels P(i,j) arranged in rows Li and columns Cj ...

Abstract

According to the invention, the image detector (100; 110; 120; 130; 200; 300; 400; 500) comprises a sensor (101; 111; 121; 131; 201; 301; 401; 501) produced on a first monolithic substrate (12) comprising a set of pixels (P(i.j)) organised in a matrix (13) in rows (Li) and columns (Cj) and configured so as to generate signals based on a radiation hitting the detector (100; 200; 300; 400); column conductors (Yj), each connecting the pixels (Pi,j) of a same column (Cj) and designed to transport the signals generated by the pixels; and at least one contact stud (14, 140) situated at the periphery of the first substrate (12) and outside the matrix (13) of pixels (P(i,j)) and connected to the column conductors (Cj). At least two column conductors (Yj) are connected to one another on the first substrate (12) outside the matrix (13) of pixels (P(i,j)), and the column conductors (Yj) connected to one another converge toward the at least one contact stud (14, 140).

Description

technical field [0001] The present invention relates to imaging devices. The invention can be implemented for image capture in detectors. Such devices include a large number of sensitive points, called pixels, typically arranged in a matrix or linear array. Background technique [0002] The invention is useful for generating visible images, but is not limited to this field. In the context of the present invention, the term "imaging" should be understood in a broad sense. For example, pressure or temperature maps or even two-dimensional representations of chemical or electrical potentials can be produced. These maps or representations form pictures of physical quantities. [0003] In a detector, a pixel represents the basic sensitive element of the detector. Each pixel converts a physical phenomenon into an electrical signal to which it is exposed. The electrical signals from the different pixels are collected during the matrix readout phase and subsequently digitized s...
