Patent ID: 7242006

Claim:
A method for manufacturing a detector for determining the position and/or energy of photons and/or charged particles comprising a plurality of diodes made of a semiconductor material and n-contacts and p-contacts, the n-contacts being provided by subdividing an n-layer into individual segments in which the segments of the n-layer are at least 20 μm wide, the n-contacts being made by Li-diffusion and have a thickness in the range of 10 to 30 μm, the thickness being achieved by removal of a surface layer of the contacts after Li-diffusion, comprising the steps of diffusing Li ions in one side of the semi-conductor material to form an n-contact; forming a desired thickness of the diffused n-contact by the subsequent removal of a top layer of the n-contact; vapor-depositing a metal layer thereon; and etching trenches through the n-contact by means of lithography for segmentation.
