Abstract:
A method of manufacturing a semiconductor device having buried gates may include forming a stacked structure of sequentially stacked first mask patterns and second mask patterns with equal widths to expose active regions and isolation regions of a semiconductor substrate. After forming reduced first mask patterns by decreasing the width only of the first mask patterns, trenches may be formed in the active regions and the isolation regions by etching the exposed portions of the semiconductor substrate using the second mask patterns as an etch mask. Then, gate insulating films may be formed on inner walls of the trenches in the active regions, and a conductive material may be buried into the trenches in the active regions and the isolation regions to form gates.
Abstract:
A bread maker to perform a bread making process including a main body forming an oven compartment; upper and lower kneading drums spaced apart from each other inside the oven compartment, each kneading drum having a holding part holding opposite ends of a mixing bag filled with dough; a drum driving part rotating the kneading drums in clockwise and counterclockwise directions to knead the dough contained in the mixing bag; an auxiliary power supply to supply power when power supply of a primary power supply is cut off; a rotation sensing part sensing rotation position of the kneading drums; and a controller which receives power from the auxiliary power supply, measures a time interval from interruption to resumption of the power supply, determines whether the measured time exceeds a predetermined limit of power-interruption time, and ends the bread making process when the measured time exceeds the predetermined limit of power-interruption time. Thus, when power supply is resumed after the power-interruption time excessively passes, the bread making process is ended, and the mixing bag is easily removed.

Abstract:
According to example embodiments of inventive concepts, a method includes forming cell patterns and insulating interlayers between the cell patterns on the substrate. An upper insulating interlayer including initial and preliminary contact holes is formed on an uppermost cell pattern. A first reflection limiting layer pattern and a first photoresist layer pattern are formed for exposing a first preliminary contact hole while covering inlet portion of the initial and preliminary contact holes. A first etching process is performed on layers under the first preliminary contact hole to expose the cell pattern at a lower position than a bottom of the first preliminary contact hole. A partial removing process of sidewall portions of the first reflection limiting layer pattern and the first photoresist layer pattern and an etching process on exposed layers through bottom portions of the preliminary contact holes are repeated for forming contact holes having different depths.
