    摘要: A multi-bit non volatile memory cell includes a first floating gate sidewall spacer structure and a second floating gate sidewall spacer structure physically separated from the first floating gate sidewall spacer structure. Each floating gate sidewall spacer structure stores charge for logically storing a bit. The floating gate sidewall spacer structures are formed adjacent to a patterned structure by sidewall spacer formation processes from a layer of floating gate material (e.g. polysilicon). A control gate is formed over the floating gate sidewall spacer structures by forming a layer of control gate material and then patterning the layer of control gate material.

    摘要: A semiconductor process and apparatus use a predetermined sequence of patterning and etching steps to etch a gate stack (62) formed over a substrate (11) and a first spacer structure (42), thereby forming etched gate structures (72, 74) that are physically separated from one another but that control a substrate channel (71) subsequently defined in the substrate (11) by source/drain regions (82, 102, 84, 104) that are implanted around the etched gate structures (72, 74). Depending on how the first spacer structure (42) is positioned and configured, the channel (71) may be controlled to provide either a logical AND gate (100) or logical OR gate (200) functionality.

    摘要: A semiconductor device (10) having a gate (16, 18 or 16, 18, 26, 28) with a thin conductive layer (18) is described. As the physical dimensions of semiconductor devices are scaled below the sub-micron regime, very thin gate dielectrics (16) are used. One problem encountered with very thin gate dielectrics is that the carriers can tunnel through the gate dielectric material, thus increasing the undesirable leakage current in the device. By using a thin layer for conductive layer (18), quantum confinement of carriers within conductive layer (18) can be induced. This quantum confinement removes modes which are propagating in the direction normal to the interfacial plane 15 from the Fermi level. Thus, the undesirable leakage current in the device (10) can be reduced. Additional conductive layers (e.g. 28) may be used to provide more carriers.

    摘要: A semiconductor substrate having a silicon layer is provided. In one embodiment, the substrate is a silicon-on-insulator (SOI) substrate having an oxide layer underlying the silicon layer. An amorphous or polycrystalline silicon germanium layer is formed overlying the silicon layer. Alternatively, germanium is implanted into a top portion of the silicon layer to form an amorphous silicon germanium layer. The silicon germanium layer is then oxidized to convert the silicon germanium layer into a silicon dioxide layer and to convert at least a portion of the silicon layer into germanium-rich silicon. The silicon dioxide layer is then removed prior to forming transistors using the germanium-rich silicon. In one embodiment, the germanium-rich silicon is selectively formed using a patterned masking layer over the silicon layer and under the silicon germanium layer. Alternatively, isolation regions may be used to define local regions of the substrate in which the germanium-rich silicon is formed.

    摘要: Field isolation regions are formed using oxidation-resistant spacers or plugs that completely fill trenches within a semiconductor substrate prior to forming the field isolation regions. The spacers or plugs help to reduce encroachment of the field isolation regions under the spacers or plugs. The structure used as an oxidation mask for the field isolation process may include a silicon-containing member that is thicker than an overlying oxidation-resistant member. The thicker silicon-containing member may be capable of tolerating higher stress before defects in an underlying pad layer or substrate are formed.

    摘要: A semiconductor device is formed having a floating gate memory cell (11) that has its channel region (33) oriented vertically with a portion of the channel region (33) that is not capacitively coupled to a floating gate (32). The memory cell (11) is less likely to be over-erased and may be programmed by source-side injection. The cell (11) may not need to be repaired after erasing. Less power may be consumed during programming compared to hot electron injection and Fowler-Nordheim tunneling.
