    Abstract: A radiation detector of the ΔE-E type is proposed. The detector is integrated in a chip of semiconductor material with a front surface and a back surface opposite the front surface, the detector having at least one detection cell arranged on the front surface for receiving a radiation to be evaluated, wherein the detector includes: a first region of a first type of conductivity extending into the chip from the front surface to a first depth; a second region of a second type of conductivity extending into the chip from the back surface to a second depth so as to reach the first region; and for each detection cell a third region of the second type of conductivity extending into the first region from the front surface to a third depth lower than the first depth and the second depth, a thin sensitive volume for absorbing energy from the radiation being defined by a junction between the first region and each third region, and a thick sensitive volume for absorbing further energy from the radiation being defined by a further junction between the first region and the second region. For each detection cell the detector further includes insulation means arranged around the third region and extending from the front surface into the first region to an insulation depth comprised between the first depth and the third depth.

    Abstract: A process including the steps of: carrying out a directional etching in a semiconductor material body to form trenches having a first width; carrying out an isotropic etching of the semiconductor material body under the trenches to form cavities having a width larger than the trenches; covering the walls of the cavities with dielectric material; depositing non-conducting material different from thermal oxide to fill the cavities at least partially, so as to form a single-crystal island separated from the rest of the semiconductor material body. The isotropic etching permits the formation of at least two adjacent cavities separated by a support region of semiconductor material, which is oxidized together with the walls of the cavities to provide a support to the island prior to filling with non-conducting material.
