摘要:
The semiconductor device of the present invention includes: particles or interface states for passing charge formed on a p-type silicon substrate via a barrier layer; and particles for holding charge formed above the charge-passing particles via another barrier layer. The charge-holding particles are different from the charge-passing particles in parameters such as the particle diameter, the capacitance, the electron affinity, and the sum of electron affinity and forbidden bandwidth, to attain swift charge injection and release as well as stable charge holding in the charge-holding particles.

The invention provides a semiconductor device, having a variety of functions such as a bistable memory and a logic circuit, in which a MOS semiconductor element, a resonance tunnel diode, a hot electron transistor and the like are formed on a common substrate. An n-type Si layer and a p-type Si layer surrounded with an isolation oxide film are formed on an SOI substrate. A mask oxide film and a gate oxide film are formed, and the n-type Si layer is subjected to crystal anisotropic etching by using the mask oxide film as a mask, so as to change the n-type Si layer into the shape of a thin Si plate. After first and second tunnel oxide films are formed on side faces of this n-type Si layer, first and second polysilicon electrodes of a resonance tunnel diode and a polysilicon electrode working as a gate electrode of a MOS semiconductor element are formed out of a common polysilicon film. Thus, a Si/SiO.sub.2 type quantum device can be manufactured with ease at a low cost.
