Single-electron transistors are very sensitive electrometers which can easily detect even the presence of an electron or ion charge in its vicinity. We have developed a technique to fabricate a linear array of tips where on each tip a metal single-electron transistor is located. These single-electron transistors can be independently operated in parallel and show nicely Coulomb blockade effect below 0.1 Kelvin. Nowadays, we use this tip array in a scanning probe microscope working in a 3He–4He dilution refrigerator.
