A method for manufacturing a solid-state image pickup device is provided. A first pixel isolation member is formed in a semiconductor substrate including pixels by implanting impurity ions in a first region of the substrate to separate pixels in the first region from each other when viewed from a surface of the substrate. A second pixel isolation member is also formed in the substrate by forming a trench in a second region of the substrate different from the first region to separate pixels in the second region from each other, and filling the trench with an electroconductive material harder to polish by CMP than the substrate. The thickness of the substrate is reduced by CMP on a rear surface of the substrate using the second pixel isolation member as a stopper.

The present invention provides a chemical-mechanical planarization method. The chemical-mechanical planarization method includes: providing a substrate including a gate and source / drain regions on the sides of the gate, the gate and the source / drain regions being overlay by an insulating layer, and the insulating layer including a protruding part above the gate and a recessed part above a surface of the substrate between gates; selectively doping the insulating layer such that only the protruding part is doped; and performing CMP on the substrate after doping, to remove the protruding part and planarize the surface of the substrate. By selectively doping the insulating layer, the method makes only the protruding part of the insulating layer doped, enhancing the corrosive attacks on the material of the protruding part by the slurry in the CMP, and increasing the removal rate of the material of the protruding part by the CMP.

A multilayer chip capacitor, and a method for manufacturing the same are provided. The capacitor includes a capacitor body having a plurality of dielectric layers stacked therein, a plurality of first and second internal electrodes formed on the dielectric layers, each of the internal electrodes including a main electrode portion and a lead portion, chip-protecting side members formed on both sides of the capacitor body to contact both sides of the first and second internal electrodes, and a pair of external electrodes formed on the outer surface of the capacitor body. The width of the main electrode portion is the same as that of the dielectric layers, and the width of the lead portion is smaller than that of the dielectric layers.

In a method of manufacturing a non-volatile memory device, a first gate insulation layer and a conductive layer are formed on a substrate and then the conductive layer is partially oxidized to form an oxide layer pattern. The conductive layer is partially etched using the oxide layer pattern as an etching mask to form a floating gate electrode on the first gate insulation layer and then the silicon layer is formed on the substrate including the floating gate electrode. The silicon layer is oxidized to form a tunnel insulation layer and a second gate insulation layer on a sidewall of the floating gate electrode and on a surface portion of the substrate adjacent to the floating gate electrode and then a control gate electrode is formed on the tunnel insulation layer and the second gate insulation layer. The present invention can restrain the change of an end profile of a floating gate electrode on the floating gate electrode and the change of the thickness of a gate insulation layer in the heating oxidation technics to form a tunnel oxide layer. Thus, the character of the data erasure and the data programme of the non-volatile memory device can be improved.

The present invention provides a method for preventing an oxide film from becoming thick due to the reaction of the oxide film and a floating gate in a method for manufacturing a flash memory device having a dielectric layer consisting of at least one oxide film between the floating gate and a control gate. To this end, a Si—F bonding layer is formed on the surface of a silicon film constituting the floating gate. The Si—F bonding layer is annealed in a nitrogen gas atmosphere to form a Si—N bonding layer. A dielectric layer is then formed.

The invention provides a lithium ion energy storage device, its pre-lithiation, and a preparation method. Specifically, one or more lithium ion energy storage devices are provided at a predetermined distance outside the cell of the lithium ion energy storage device and in a direction perpendicular to the pole piece. The pre-lithiation electrode is then charged or discharged by the pre-lithiation electrode and the positive electrode and the negative electrode, so that the lithium ions in the pre-lithiation electrode pass through the gap between the positive electrode, the negative electrode and the separator along the direction parallel to the electrode sheet. Entering the inside of the electrode, this pre-lithiation method avoids the design scheme that lithium ions must pass through the pole piece of the energy storage device in the vertical direction in the traditional pre-lithiation method, and completely overcomes the need for positive and negative foils to be holes. The disadvantages of foil and the resulting adverse effects on the preparation efficiency and finished product quality make the preparation process simpler and more controllable. At the same time, this technology can also be used for the secondary lithium replenishment operation of finished lithium ion energy storage devices, which is a lithium ion energy storage device. The regeneration of the energy storage device helps.

Upon formation of a layer such as an emissive layer of an organic EL element by attaching an emissive material onto a substrate (10), an evaporation mask (100) including an opening (110) corresponding to the layer formed to have a plurality of individual patterns and having an area, for example, smaller than the substrate is disposed between the substrate (10) and a material source (200). A relative position between the mask (100) and the material source (200), and the substrate (10) is slid by a predetermined pitch corresponding to the size of a pixel of the substrate (10), thereby forming a material layer (such as the emissive layer 64) in a predetermined region of the substrate. As a result, the material layer can be formed on the substrate through, for example, evaporation with a high accuracy.

The purpose of the present invention is to provide a blow-moulded container onto which an oil film can be formed without unevenness across the entire inner surface of the container by coating the inner surface with an oil-based liquid.
