An electrical device including a PTC conductive polymer sheet, and first and second electrodes physically contacted with opposite surfaces of the conductive polymer sheet is disclosed. The first and second electrodes have a plurality of protrusions protruded from surfaces thereof, respectively. The protrusions have an surface roughness (Rz) of 1 to 20 μm and an average width ({overscore (Rw)}) which is 0.5 to 2 times of the surface roughness (Rz), and an average gap ({overscore (Rg)}) between adjacent protrusions is 0.5 and 2 times of the surface roughness (Rz). The conductive polymer sheet has a thickness which is more than 5 times of the surface roughness (Rz).
Abstract:
Methods of fabricating high-k dielectric layers having reduced impurities for use in semiconductor applications are disclosed. The methods include the steps of: forming a stacked dielectric layer having a first dielectric layer and a second dielectric layer formed on a semiconductor substrate using an ALD method, in combination with a post-treatment step performed to the stacked dielectric layer. The steps of forming the stacked dielectric layer and performing the post-treatment are repeated at least once, thereby fabricating the high-k dielectric layer.
Abstract:
A torsion spring is equipped to provide a resilient force toward an opposite direction of a manipulation force of a driver's pedal and an magnetorheological damper is equipped to promptly actively attenuate the resilient force of the torsion spring and the manipulation force of the driver's pedal. Thereby, contributing to a wide control range of the reaction force of the pedal, an effective response, and a proper formation of hysteresis of the reaction force of the pedal.
Abstract:
A method for forming a dual gate includes providing a semiconductor substrate that has a first region of a first conductivity type and a second region of a second conductivity type. A gate insulating layer is formed on the semiconductor substrate. An initial metal nitride layer is formed on the gate insulating layer, opposite to the semiconductor substrate. Nitrogen ions are implanted into the initial metal nitride layer in the second transistor region to form a nitrogen-rich metal nitride layer. The initial metal nitride layer is patterned to form a first gate electrode in the first region. The nitrogen-rich metal nitride layer is patterned to form a second gate electrode in the second region. The work function of the nitrogen-rich metal nitride layer is higher than that of the initial metal nitride layer.
Abstract:
Field effect transistors include a semiconductor substrate having a channel region of first conductivity type therein extending adjacent a surface thereof. Source and drain regions of second conductivity type are also provided at opposite ends of the channel region. The source and drain regions extend in the semiconductor substrate and form P-N rectifying junctions with the channel region. A gate electrode extends on the channel region and comprises a first electrically conductive material having a first work function. A first sub-gate electrode extends on the channel region and comprises a second electrically conductive material having a second work function that is unequal to the first work function. The second electrically conductive material is preferably selected so that a difference between the second work function and a work function of the channel region is sufficient to form an inversion-layer in a portion of the channel region extending opposite the first sub-gate electrode when the first sub-gate electrode is at a zero potential bias relative to the channel region.
