Patent ID: 6838674

Claim:
A method for producing a two-dimensional detector array ( 25 ) for detection of electromagnetic radiation, comprising the steps of: a) forming a stack ( 1 ) from a sequence of layers which are arranged one above the other in a stacking direction ( 3 ) and are connected to one another, said sequence of layers comprising at least one sensor layer ( 9 A, 9 B, . . . , 9 H) composed of a material (M) which is sensitive to said radiation and a separating layer ( 5 ), being produced repeatedly, b) breaking the stack ( 1 ) down into slabs ( 13 A, 13 B, . . . ) such that a row sequence in one slab ( 13 A, 13 B, . . . ) reproduces the layer sequence in the stack ( 1 ), c) applying a covering layer ( 15 ) on one of the surface faces of one slab ( 13 A, 13 B, . . . ), d) subdividing the rows of the one slab into individual sensor elements by incorporating separating spaces ( 21 ), all separating spaces originating from the face facing away from the covering layer ( 15 ) and extending into the covering layer ( 15 ), e) introducing a reflector material (R) which reflects radiation emitted from said material (M) into the separating spaces ( 2 l) produced during the subdivision step, and f) contacting the one slab ( 13 A, 13 B, . . . ), optically or electrically, on at least one of its surface faces, the resulting one slab with individual sensor elements being a two-dimensional detector array.
