摘要： A layered semiconductor device with a nonvolatile three dimensional memory comprises a storage channel which stores charge carriers. Charge carriers flow laterally through the storage channel from a source to a drain. Isolation material, either a Schottky barrier or a heterojunction, located in a trench of an upper layer controllably retains the charge within the a storage portion determined by the confining means. The charge is retained for a time determined by the isolation materials' nonvolatile characteristics or until a change of voltage on the isolation material and the source and drain permit a read operation. Flow of charge through an underlying sense channel is affected by the presence of charge within the storage channel, thus the presences of charge in the memory can be easily detected.

The floating layer is formed into a three-layer structure of a p-AlGaAs layer, an i-InGaAs layer and a p-AlGaAs layer. It is possible to provide a semiconductor device capable of securing its sufficient functionality at a room temperature by using a quantum dot structure, and achieving an ultimate high-density integration with high reliability. Also provided is a method capable of easily manufacturing semiconductor devices having such a construction.
