  • Patent number: 7968950
    Abstract: A semiconductor device includes a gate electrode having ends that overlap isolation regions, wherein the gate electrode is located over an active region located within a semiconductor substrate. A gate oxide is located between the gate electrode and the active regions, and source/drains are located adjacent the gate electrode and within the active region. An etch stop layer is located over the gate electrode and the gate electrode has at least one electrical contact that extends through the etch stop layer and contacts a portion of the gate electrode that in one embodiment overlies the active region, and in another embodiment is less than one alignment tolerance from the active region.

  • Publication number: 20100052025
    Abstract: A silicon on insulator (SOI) multi-gate field effect transistor electrically Programmable Read-Only Memory (MuFET EPROM) includes a substrate having a dielectric surface. A first semiconducting region is in or on the dielectric surface. A source region, a drain region and a channel region interposed between the source and drain are formed in first semiconducting region. A gate dielectric layer is on the channel region. At least a second semiconducting region in or on the dielectric surface is spaced apart from the first semiconducting region. A first electrode layer comprises a first electrode portion including a transistor gate electrode and a control gate electrode electrically isolated from one another. The transistor gate overlies the channel region to form a transistor. The control gate extends to overlay a portion of the second semiconducting region.
