Abstract: According to one embodiment, a method is disclosed for manufacturing a semiconductor device. The method includes forming a second stacked body on the planarized interlayer insulating film and on the uppermost stair. The second stacked body includes a second conductive film thicker than the first conductive film and a second insulating film stacked on the second conductive film. The method includes dividing the second stacked body into a select gate on the uppermost stair and a plurality of wall portions in a staircase region below the uppermost stair. The method includes forming a plurality of vias piercing the interlayer insulating film under a region between the wall portions and reaching the first conductive film of each of the stairs.
Abstract: A process is described for producing silicon carbide crystals having increased minority carrier lifetimes. The process includes the steps of heating and slowly cooling a silicon carbide crystal having a first concentration of minority carrier recombination centers such that the resultant concentration of minority carrier recombination centers is lower than the first concentration.

Abstract: A method of controlling ferroelectric characteristics of integrated circuit device components includes forming a ferroelectrically controllable dielectric layer over a substrate; and forming a stress exerting structure proximate the ferroelectrically controllable dielectric layer such that a substantially uniaxial strain is induced in the ferroelectrically controllable dielectric layer by the stress exerting structure; wherein the ferroelectrically controllable dielectric layer comprises one or more of: a ferroelectric oxide layer and a normally non-ferroelectric material layer that does not exhibit ferroelectric properties in the absence of an applied stress.

Abstract: A semiconductor device may include a semiconductor layer having a convex portion and a concave portion surrounding the convex portion. The semiconductor device may further include a protrusion type isolation layer filling the concave portion and extending upward so that an uppermost surface of the isolation layer is a at level higher that an uppermost surface of the convex portion.
Abstract: A group III-V material CMOS device may have NMOS and PMOS portions that are substantially the same through several of their layers. This may make the CMOS device easy to make and prevent coefficient of thermal expansion mismatches between the NMOS and PMOS portions.
