Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. An integrated circuit structure, comprising:
a semiconductor material having a particular conductivity type;
a first transistor in a first active area in the semiconductor material;
a second transistor in a second active area in the semiconductor material;
a first conductor forming a control gate of the first transistor;
a second conductor forming a control gate of the second transistor; and
an isolation structure comprising a dielectric material deposited in a trench formed in the semiconductor material between the first active area and the second active area, the isolation structure further comprising:
a first edge portion extending below a surface of the semiconductor material to a first depth;
a second edge portion extending below the surface of the semiconductor material to the first depth; and
an interior portion between the first edge portion and the second edge portion, and extending below the surface of the semiconductor material to a second depth, less than the first depth, for a distance that si greater than or equal to a width of the first active area;

wherein the isolation structure has an orientation that is parallel to the first conductor and parallel to the second conductor.
