For the purpose of development of novel functional devices such as quantum information devices, single electron transistors, and sensitive sensors, quantum dots (QDs) attract a great deal of attention. We develop experimentally and theoretically various QD device structures in Si [1-4]. In order to fabricate lithographically-defined Si QDs, we utilize electron beam lithography, reactive ion etching, and oxidation, in a metal-oxide-semiconductor (MOS) structure on a non-doped silicon-oninsulator (SOI) substrate. We apply the fabrication process of Si MOS technologies into our QD devices. We study both n-channel and p-channel Si QD devices. We clearly observed Coulomb oscillation, which is the evidence of single carrier tunneling. Charge detection of change in number of carriers (electrons for n-channel QDs and holes for p-channel QDs) in QDs, one by one, has been successfully demonstrated using the device where we attached single QDs as charge sensors in the vicinity of the double QDs. Few-electron and few-hole regimes in QDs are also realized in n- channel and p- channel QD devices, respectively. These achievements are the important steps for realizing quantum information devices, single electron transistors, and sensitive sensors.
