    Abstract: PURPOSE: To provide an integrated circuit structure, capable of forming a hybrid type integrated circuit having at least one EPROM without adding a special working step for the hybrid type integrated circuit regarding the integrated circuit. CONSTITUTION: An EPROM cell has an active region 18, and the region is formed by the same operation as the formation of a P-type region 17, in which an N -channel MOS transistor is housed. Likewise, each region of sources and drains is formed by the same operation as the formation of the source regions and drain regions 31 of the transistors, control electrodes 15 consisting of N - type regions are shaped by the same operation as the formation of deep regions 14 communicating each N -type embedded region, and floating gate electrodes 24 formed of one conductive material layer are formed by the same operation as the formation of the gate electrodes 23 of the transistors in an integrated circuit.

    Abstract: High-Q, variable capacitance capacitor (20, 20'), comprising a pocket (22) of semiconductor material; a field insulating layer (23), covering the pocket; an opening (24) in the field insulating layer, delimiting a first active area (24); an access region (25) formed in the active area and extending at a distance from a first edge (24a) of the active area and adjacent to a second edge (24b) of the active area. A portion (26) of the pocket (22) is comprised between the access region (15) and the first edge (24a) and forms a first armature; an insulating region (30) extends above the portion (26) of said body, and a polysilicon region (31) extends above the insulating region (30) and forms a second armature. A portion of the polysilicon region extends above the field insulating layer (23), parallel to the access region (25); a plurality of contacts (32) are formed at a mutual distance along the portion of the polysilicon region (31) extending above the field insulating layer (23).

    Abstract: An integrated circuit structure is disclosed wherein an EPROM cell has an active area (18) formed by the same operations as are necessary to form a P region (17) intended to contain an N-channel MOS transistor, source and drain regions formed by the same operations as are necessary to form the source and drain regions (31) of said transistor, a control electrode (15) consisting of an N+ region formed by the same operations as are carried out to form deep regions (14) intended to contact buried N+ regions, and a floating gate electrode (24) consisting of a layer of conductive material formed by the same operations as are carried out to form the gate electrodes (23) of the MOS transistors in the integrated circuit. The EPROM cell can, therefore, be formed in a mixed integrated circuit with no need for purposely added processing steps.
