Abstract:
A method for fabricating an SRAM, comprising the steps of:forming a drive transistor on a substrate, the drive transistor including a gate electrode and a first gate insulating layer interposed between the gate electrode and the substrate;forming first impurity regions in the substrate on opposite sides of the gate electrode of the drive transistor;forming an insulating layer over the substrate, the insulating layer having a contact hole exposing a portion of the gate electrode of the drive transistor;forming a semiconductor layer connected to the gate electrode of the drive transistor through the contact hole on the insulating layer;forming a second gate insulating layer on the semiconductor layer;forming an access transistor over the substrate, the access transistor including a gate electrode on the second gate insulating layer;forming second impurity regions in the semiconductor layer on opposite sides of the gate electrode of the access transistor;forming a load resistor connected to a first one of the second impurity regions; andforming a bit line connected to a second one of the second impurity regions.
