Patent application numberDescriptionPublished
20110081581ORGANIC ELECTROLYTIC SOLUTION WITH SURFACTANT AND LITHIUM BATTERY EMPLOYING THE SAME - An organic electrolytic solution and a lithium battery employing the same are provided. The organic electrolytic solution includes a lithium salt, an organic solvent containing a first solvent having a high dielectric constant and a second solvent having a low boiling point, and a surfactant including a hydrophobic portion having an aromatic group. The organic electrolytic solution effectively prevents the electrolytic solution from contacting the anode, thereby suppressing side reactions on the anode surface and improving discharge capacity, charge/discharge efficiency, lifespan, and battery reliability.04-07-2011

20100309368WAFER-LEVEL LENS MODULE AND IMAGE PICKUP MODULE INCLUDING THE SAME - Provided are a wafer-level lens module and an image pickup module including the same. The wafer lens module includes a plurality wafer-scale lenses. At least one of the plurality of wafer-scale lenses, such as a wafer-scale lens positioned toward an object side, includes a substrate and a glass lens element formed on one side of the substrate. The glass lens element may be a one-sided lens or a double-sided lens. When the glass lens is a double-sided lens, the substrate may have a through hole. The remaining wafer-scale lenses each include a substrate and polymer lens elements made of UV curable polymer and formed on both sides of the substrate. Also, spacers are interposed between the wafer-scale lenses, along the edge portions of the substrates, so as to maintain predetermined intervals between the wafer-scale lenses.12-09-2010
20110037887WAFER-LEVEL LENS MODULE AND IMAGE PICKUP DEVICE INCLUDING THE SAME - Disclosed are a wafer-level lens module including a plurality of wafer-scale lenses that are stacked and an image pickup device including the wafer-level lens module and an image sensor. Each wafer-scale lens includes a substrate with a light-transmission part, and a lens element fixed on one side or both sides of the substrate. The lens element includes an optical zone, corresponding to the light-transmission part of the substrate, and an extended zone disposed outside the optical zone. A trench or protrusion is formed as an alignment guide on one or both sides of the substrate, adjacent to the light-transmission part, and a protrusion or trench, aligned with the trench or protrusion, is formed in the extended zone of the lens element. The lens element is aligned on the substrate such that an inclined portion of the protrusion contacts corners of the trench.02-17-2011

20100142061MICRO LENS, METHOD AND APPARATUS FOR MANUFACTURING MICRO LENS, AND CAMERA MODULE INCLUDING MICRO LENS - Micro lens manufacturing apparatus, a micro lens manufacturing method, a micro lens, and a camera module employing the micro lens are provided. First mold is manufactured in correspondence with a first lens profile of a lens element. Second mold is manufactured in correspondence with a second lens profile of the lens element. Second mold is aligned on a surface of a lens substrate having a hollow hole formed thereon. Material for the lens element is supplied into the hollow hole of the lens substrate. First mold is aligned on the other surface of the lens substrate having the hollow hole and compressed to form the first and second profiles of the lens element. Formed lens element hardened. First and second molds are separated from each other. Therefore, time and cost for manufacturing the micro lens are reduced, and the accurate alignment between the first and second lens profiles is achieved.06-10-2010

20080213966INDUCTOR EMBEDDED IN SUBSTRATE, MANUFACTURING METHOD THEREOF, MICRO DEVICE PACKAGE, AND MANUFACTURING METHOD OF CAP FOR MICRO DEVICE PACKAGE - An inductor embedded in a substrate, including a substrate, a coil electrode formed by filling a metal in a spiral hole formed on the substrate, an insulation layer formed on the substrate, and an external connection pad formed on the insulation layer to be connected to the coil electrode. The inductor-embedded substrate can be used as a cap for a micro device package by forming a cavity on its bottom surface.09-04-2008
20090115875IMAGE SENSOR MODULE AND FABRICATION METHOD THEREOF - An image sensor module having a sensor chip closely adhered on a concave surface and a fabrication method thereof are disclosed. The image sensor module includes at least one sensor chip, at least one sensor chip-mounting structure comprising a substrate and a polymer layer formed on the substrate, the polymer layer having an concave surface formed on an upper part thereof by a polymer molding method, so that the sensor chip is bent and bonded on the concave surface, and at least one lens fixed on the at least one sensor chip-mounting structure above the sensor chip.05-07-2009
20100050412PART BEING CENTERED DURING ASSEMBLY PROCESS, WAFER LEVEL PARTS ASSEMBLY, AND APPARATUS AND METHOD TO MANUFACTURE WAFER LEVEL PARTS ASSEMBLY - A part to be centered during an assembly process includes an effective portion which performs a function and is shaped for insertion into a hole, a reference portion extended from the effective portion and formed substantially perpendicular to a center axis of the effective portion, and an aligning portion extended from the effective portion and formed around the effective portion. When the effective portion of the part is inserted into the hole, a center of the effective portion is automatically aligned with a centerline of the hole.03-04-2010

20090279230Electrode structure for the manufacture of an electric double layer capacitor - A method is provided of manufacturing an electrode for an electric double layer capacitor, including mixing an active material, a conductive material and a binder. In this method, Ketjen Black is used as the conductive material and a fluorosurfactant is an additive for enhancing fluidity of the slurry. Also, an electrode for an electric double layer capacitor and an electric double layer capacitor using the electrode are provided. Use of the electric double layer capacitor increases the amount of the active material, so that the electrical capacitance is increased, thus providing the electric double layer capacitor in which the amount of the conductive material is decreased and the electrical resistance is decreased.11-12-2009
