    摘要： A multilevel sense circuit includes a memory MOSFET having one of at least two different current carrying states and a pair of reference MOSFETs one of which has one of the two current carrying states and the other of which has the other current carrying state. A first current supplying circuit is connected to the memory MOSFET for supplying a predetermined amount of current thereto when the memory MOSFET is activated. A second current supplying circuit is connected to the pair of reference MOSFETs and also to the first current supplying circuit, such that twice the aforementioned predetermined amount of current is supplied to the pair of reference MOSFETs when the memory MOSFET is activated. A multilevel semiconductor memory device includes a MOSFET having a channel whose width is varyingly set by providing a non-inverting region in a selected area of the channel by ion implantation.

    摘要： A method of manufacturing a semiconductor integrated circuit device having a SOI structure includes the following steps. The first step is to form a semiconductor layer on a dielectric substrate. The second step is to form an oxide layer on the formed semiconductor layer. The third step is to form a nitride layer on the formed oxide layer. The fourth step is to remove a part of a plurality of layers composed of the semiconductor layer, the oxide layer, and a nitride layer so as to form a separated region in the layers. The fifth step is to coat a cooling agent on a surface of the nitride layer. The sixth step is to irradiate an energy beam from an outer surface of the cooling agent so as to monocrystallize the semiconductor layer. The seventh step is to remove the cooling agent from the surface of the nitride layer. And the final step is to oxidize a portion of the semiconductor layer located in the separated region by using the nitride layer. A semiconductor integrated circuit device having a SOI structure includes a semiconductor layer formed on a dielectric substrate, an oxide film formed on the semiconductor layer, a nitride layer formed on the oxide film, and a monocrystallized and oxidized semiconductor layer formed in hole portions formed in the semiconductor layer passing through the oxide layer and the nitride layer.
