    Abstract: Disclosed are a capacitor for DRAM, a DRAM including the same, and a method of fabricating the same. The DRAM capacitor according to an embodiment may include a first electrode of the DRAM; a second electrode spaced apart from the first electrode; and a dielectric layer including a HfZrO film disposed between the first electrode and the second electrode. The HfZrO film may have an intermediate state corresponding to a phase transition region between a first state in which a tetragonal crystalline phase with anti-ferroelectricity property or a tetragonal crystalline phase is dominant, and a second state in which the orthorhombic crystalline phase with anti-ferroelectricity property or the orthorhombic crystalline phase is dominant. The HfZrO film may include both of the tetragonal crystalline phase and the orthorhombic crystalline phase. The HfZrO film maintains an intermediate state corresponding to the phase transition region within the operating voltage range of the capacitor.

    Abstract: A steep-slope field-effect transistor and a fabrication method thereof are disclosed. The steep-slope field-effect transistor according to an embodiment of the inventive concept includes a source, a channel region, and a drain formed on a substrate; a gate insulating film formed on an upper portion of the channel region; a floating gate formed on an upper portion of the gate insulating film; a transition layer formed on an upper portion of the floating gate; and a control gate formed on an upper portion of the transition layer. The steep-slope field-effect transistor applies a reference potential or more to the control gate to discharge or bring in at least one charge stored in the floating gate.

    Abstract: An elasticity measurement apparatus includes a lower layer structure having first and second openings, first and second deformable membranes covering the first and second openings to define first and second chamber and deformable by pressure within the first and second chambers respectively, a support layer structure on the lower layer structure to protrude and configured to support the first and second deformable membranes to be spaced apart from the elastic body, a driving portion to apply pressure within the first and second chambers to deform the first and second deformable membranes, and first and second deformation detecting portions to detect deformations of first and second deformable membranes. When the pressure within the first and second chambers is increased from a first pressure to a second pressure, the first deformable membrane is deformed with contacting the elastic body, while the second deformable membrane is deformed without contacting the elastic body.
