Abstract:
Integrated circuits and methods for fabricating integrated circuits are provided. In an exemplary embodiment, an integrated circuit includes a semiconductor substrate doped with a first conductivity-determining impurity. The semiconductor substrate has formed therein a first well doped with a second conductivity-determining impurity that is different from the first conductivity-determining impurity, a second well, formed within the first well, and doped with the first conductivity-determining impurity, and a third well spaced apart from the first and second wells and doped with the first conductivity-determining impurity. The integrated circuit further includes a floating gate structure formed over the semiconductor substrate. The floating gate structure includes a first gate element disposed over the second well and being separated from the second well with a dielectric layer, a second gate element disposed over the third well and being separated from the third well with the dielectric layer, and a conductive connector.

Abstract:
Integrated circuits that include bi-directional protection diode structures are disclosed. In one example, an integrated circuit includes a test circuit portion for testing the functionality of the integrated circuit during or after fabrication of the integrated circuit. The test circuit portion includes first, second, and third diode structures and a resistor structure. The first and third diode structures are in parallel with one another and in series with the resistor, and the resistor and the first and third diode structures are in series with the second diode structure. The first and third diode structures are configured for current flow in a first direction and the second diode structure is configured for current flow in a second direction that is opposite the first direction.
