A detector device comprises a substrate (50), a source region (S) and a drain region (D), and a channel region (65) between the source and drain regions. A nanopore (54) passes through the channel region, and connects fluid chambers (56,58) on opposite sides of the substrate. A voltage bias is provided between the fluid chambers, the source and drain regions and a charge flow between the source and drain regions is sensed. The device uses a nanopore for the confinement of a sample under test (for example nucleotides) close to a sensor. The size of the sensor can be made similar to the spacing of adjacent nucleotides in a DNA strand. In this way, the disadvantages of PCR based techniques for DNA sequencing are avoided, and single nucleotide resolution can be attained.

A method of manufacturing a semiconductor device with a MOS transistor having an LDD structure. A gate dielectric (6) and a gate electrode (7, 8) are formed on a surface (5) of a silicon substrate (1). The surface adjacent the gate electrode is then exposed, and a layer of semiconductor material (10) is formed on an edge (9) of the surface adjoining the gate electrode. Ions (13, 14) are subsequently implated, with the gate electrode and the layer of semiconductor material acting as a mask. Finally, a heat treatment is carried out whereby a source zone (16, 17) and a drain zone (18, 19) are formed through activation of the implanted ions and through diffusion of atoms of a dopant from the layer of semiconductor material. The portions (b) of these zones formed by diffusion are weakly doped here and lie between the more strongly doped portions (a) formed through activation of implanted ions and the channel zone (20, 21). An LDD structure has thus been formed. In the method, a layer of semiconductor material formed by Si1-xGex, 0.1

A method of forming a transistor structure on a substrate (SOI) is disclosed, wherein the substrate comprises a supporting Si layer, a buried insulating layer, and a top Si layer. The method comprises forming a gate region of the transistor structure on the top Si layer, wherein the gate region is separated from the top Si layer by a dielectric layer, and wherein the top Si layer comprises a high dopant level. The method further comprises forming an open area on the top Si layer demarcated by a demarcating oxide and/or resist layer region, forming high level impurity or heavily-damaged regions by ion implantation, and exposing the open area to an ion beam, wherein the ion beam comprises a combination of beam energy and dose, and wherein the demarcating layer region and the gate region act as an implantation mask.
