Abstract: A method of manufacturing a semiconductor device includes: forming electrode holes by etching a mold structure including a mold layer and a support layer which are stacked on a substrate; forming lower electrode pillars filling the electrode holes; etching a portion of the support layer between the lower electrode pillars to form a support pattern having a through-hole exposing a portion of a top surface of the mold layer; removing the mold layer through the through-hole to expose sidewalls of the lower electrode pillars; and selectively forming lower electrode patterns on the sidewalls and top surfaces of the lower electrode pillars.

Abstract: A semiconductor device includes; a bottom electrode on a substrate, a supporting pattern between the bottom electrode and an adjacent bottom electrode, a top electrode covering the bottom electrode and the supporting pattern, and a dielectric layer between the bottom electrode and the top electrode and between the supporting pattern and the top electrode. The bottom electrode may include a first portion including a seam and a second portion on the first portion, a top end of the second portion may be disposed at a height lower than an upper surface of the supporting pattern, and a portion of a bottom end of the second portion may be exposed to the seam.

Abstract: A bidet body that includes at least one of a drying nozzle and a cleaning nozzle moving in one of a forward and downward direction and an upward and backward direction, and a bottom surface of a cover that constitutes an exterior of the bidet body may be flat.

Abstract: A drying device includes: a housing having a ventilation device provided therein; a drying nozzle provided in the housing, and having a ventilation groove from which an air flow generated by the ventilation device is discharged; and a driving motor for moving the drying nozzle forward and backward by rotating the drying nozzle.

Abstract: Provided is a bidet body. In the bidet body according to an embodiment of the present disclosure, at least one of a drying nozzle and a cleaning nozzle moving in one of a forward and downward direction and an upward and backward direction may be installed, and a bottom surface (111) of a cover (110) constituting an exterior of the bidet body may be flat.

Abstract: A flow rate control valve has a waterproof function of a driving motor. The flow rate control valve is for transferring a fluid pumped by a water supply pump to a nozzle unit and a nozzle cleaning unit for cleaning the nozzle unit. The flow rate control valve includes al least one housing in which the fluid pumped by the water supply pump is accommodated, and at least one driving motor configured to change a communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by rotation. At least one sealing adapter is formed between the at least one housing and the at least one driving motor so as to prevent the fluid from flowing into the at least one driving motor.

Abstract: A hot water tank for a bidet includes a tank main body in which a space for accommodating water is formed and an inclined surface having a portion of an upper side inclined downward is formed. The hot water tank also includes a heating unit inserted into and positioned in the tank main body and a bimetal positioned on the inclined surface.

Abstract: A drying device includes: a housing having a ventilation device provided therein; a drying nozzle provided in the housing, and having a ventilation groove from which an air flow generated by the ventilation device is discharged; and a driving motor for moving the drying nozzle forward and backward by rotating the drying nozzle.

Abstract: The present invention provides a semi-automatic pressure type water softener including: an ionic resin tank (100) provided with an ionic resin; a regeneration vessel (200), into which a regenerant is introduced and which generates reclaimed water filled with the ionic resin; a drain valve (293) provided in the regeneration vessel (200) and configured to discharge residual water to the outside; a water inlet part (400) configured to selectively supply raw water to the ionic resin tank (100) and the regeneration vessel (200); and a timer/ceramic disk conversion valve (300) configured to select any one of a water softening mode, a raw water mode, and a regeneration mode to convert a passage between any two of the water inlet part (400), the ionic resin tank (100), and the regeneration tank (200), wherein the water softener is in the regeneration mode, any one of a first mode and a second mode is selected according to a preset method, wherein the first mode is operated for a preset period of time by the timer/cer

Abstract: There are provided a toilet cleaning apparatus having a bubble supply mechanism and a cleaning method thereof. The toilet cleaning apparatus having a bubble supply mechanism includes a mixture tank in which raw water supplied from a raw water supply unit, air introduced from an air supply unit, and a cleaning solution supplied from a cleaning solution supply unit are mixed and accommodated, a bubble generation unit provided in the mixture tank and generating bubbles with the raw water, air, and the cleaning solution by using an impeller, and a bubble discharging unit connected to the mixture tank and discharging bubbles generated by the bubble generation unit to the toilet bowl to cover water stored in the toilet.
