Abstract
The invention relates to field effect transistors having a non-volatile memory effect of the MIS type. According to the invention the transistor comprises, in addition to substrate (17), a source (21), a drain (22), a grid formed by a semi-insulating film (18) and an insulating layer (19), whose semi-insulating film (18) has a thickness below 100 angstroms and is formed from a semiconductive material of groups III-V having a broader forbidden band than that of the active layer (16) on which it is deposited. Useful applications of the invention include ultra-high frequency transistors for telecommunications.
