    摘要: An integrated circuit contains a planar first transistor and a diode. The diode is connected between a first source/drain region of the first transistor and a gate electrode of the first transistor such that a charge is impeded from discharging from the gate electrode to the first source/drain region. A diode layer that is part of the diode is disposed on a portion of the first source/drain region. A conductive structure that is an additional part of the diode is disposed above a portion of the gate electrode and is disposed on the diode layer. The diode can be configured as a tunnel diode. The diode layer can be produced by thermal oxidation. Only one mask is required for producing the diode. A capacitor can be disposed above the diode. The first capacitor electrode of the capacitor is connected to the conductive structure.

    摘要: Memory cell transistors with back-channel isolation are produced without using an SOI substrate. With the word line stack acting as a mask, the semiconductor material is etched on both sides of the world line, first anisotropically and then isotropically to widen the etch hole and form an undercut beneath the gate electrode and at a distance from the ONO storage layer forming the gate dielectric. The undercut is filled, whereby a buried oxide layer of at least 20 nm maximum thickness is formed underneath the channel region. The latter is p-doped at a density of at least 1017 cm−3.

    摘要: A memory array includes first, second, third and forth memory cell strings. Each of the first, second, third, and fourth memory cell strings includes a number of serially-coupled memory cells, including a first memory cell and a last memory cell. A first interconnect is coupled to a first bit line and to each of the first, second, third and fourth memory cell strings. The first interconnect includes first, second, third and fourth string input select gates. Each input select gate has a first terminal coupled to the first bit line, and a second terminal coupled to one of the respective first, second, third or fourth memory cell strings.

    摘要: A memory layer intended for trapping charge carriers over a source region and a drain region is interrupted over the channel so that a diffusion of the charge carriers, which are trapped over the source region and over the drain region, is prevented. The memory layer is limited to regions over the parts of the source region and of the drain region facing the channel and is embedded all around in oxide.
