摘要： A method of forming a multi-floor step pattern structure includes forming a stacked structure having alternating insulating interlayers and sacrificial layers on a substrate. A first photoresist pattern is formed on the stacked structure. A first preliminary step pattern structure is formed by etching portions of the stacked structure using the first photoresist pattern as an etching mask. A passivation layer pattern is formed on upper surfaces of the first photoresist pattern and the first preliminary step pattern structure. A second photoresist pattern is formed by removing a side wall portion of the first photoresist pattern exposed by the passivation layer pattern. A second preliminary step pattern structure is formed by etching exposed insulating interlayers and underlying sacrificial layers using the second photoresist pattern as an etching mask. The above steps may be repeated on the second preliminary step pattern structure to form the multi-floor step pattern structure.

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.

摘要： Disclosed is a radio frequency filter of a combline structure including a frequency cut-off circuit for cutting off a specific frequency from a frequency band having a given frequency bandwidth. The frequency cut-off circuit includes an inductive transmission line extending from the output terminal by a length determined to provide an approximate inductance corresponding to a calculated value approximate to an inductance for obtaining the specific frequency, and a capacitive element coupled to the approximate inductance provided by the inductive transmission line, so that it has a capacitance for obtaining the specific frequency. The inductive transmission line is connected to the capacitive element through a via hole formed at an end of the transmission line opposite to the output terminal, from which the transmission line extends. The invention also proposes a method for implementing the radio frequency filter.

摘要： Disclosed is a technique for obtaining an estimate and variance of each variable based on a constraint manifold. Particles (or samples) are sampled in order to filter and fuse ambiguous data or information on at least one state variable of a system using the particles. The sampling is carried out in consideration of an influence which non-linearity of the constraint manifold of a system model, an observation model or another system model exerts on a probability distribution of the state variable. With this construction, it is possible to reduce decrease of fusion and filtering performance, decrease a Gaussian approximation error, and detect mismatched information.

摘要： An impulse generation circuit is provided for generating an impulse using a transmission line. Impulse characteristics of the impulse generation circuit are varied with the length of a transmission line rather than the characteristic variation of various devices used therein. The length of the transmission line is adjusted, such that a width of a generated pulse is adjusted. Because an end of the transmission line is short-circuited, the transmission line length can be easily adjusted on a substrate, and a ringing phenomenon due to re-reflection can be removed using termination impedance.

摘要： After an insulation layer is formed on a substrate, a contact hole is formed through the insulation layer. A recessed plug is formed to partially fill up the contact hole. The recessed plug has a height substantially smaller than a depth of the contact hole. A metal wiring structure is formed on the recessed plug and on the insulation layer. A lower portion of the metal wiring structure, formed within the contact hole, prevents damage to the recessed plug during an etching process for forming the metal wiring structure. Therefore, the recessed plug may be formed without damage thereof even if an alignment error occurs between an etching mask and the recessed plug during metal wiring structure formation.
