    摘要: A field effect transistor is formed having wrap-around, vertically-aligned, dual gate electrodes. Starting with a silicon-on-insulator (SOI) structure having a buried silicon island, a vertical reference edge is defined, by creating a cavity within the SOI structure, and used during two etch-back steps that can be reliably performed. The first etch-back removes a portion of an oxide layer for a first distance over which a gate conductor material is then applied. The second etch-back removes a portion of the gate conductor material for a second distance. The difference between the first and second distances defines the gate length of the eventual device. After stripping away the oxide layers, a vertical gate electrode is revealed that surrounds the buried silicon island on all four side surfaces.

    摘要: A method for simultaneously forming multiple line-widths, one of which is less than that achievable employing conventional lithographic techniques. The method includes providing a structure which includes a memory layer and a sidewall image transfer (SIT) layer on top of the memory layer. Then, the SIT layer is patterned resulting in a SIT region. Then, the SIT region is used as a blocking mask during directional etching of the memory layer resulting in a first memory region. Then, a side wall of the SIT region is retreated a retreating distance D in a reference direction resulting in a SIT portion. Said patterning comprises a lithographic process. The retreating distance D is less than a critical dimension CD associated with the lithographic process. The SIT region includes a first dimension W2 and a second dimension W3 in the reference direction, wherein CD

    摘要: Novel semiconductor structures and methods are disclosed for forming a buried recombination layer underneath the bulk portion of a hybrid orientation technology by implanting at least one recombination center generating element to reduce single event upset rates in CMOS devices thereabove. The crystalline defects in the buried recombination layer caused by the recombination center generating elements are not healed even after a high temperature anneal and serve as recombination centers where holes and electrons generated by ionizing radiation are collected by. Multiple buried recombination layers may be formed. Optionally, one such layer may be biased with a positive voltage to prevent latchup by collecting electrons.
