Abstract: An electronic device includes: a capacitor; an insulating layer; at feast one trench provided in the insulating layer; and a first conductive plug, at least part of which is surrounded by the insulating layer. The capacitor includes: a first lower electrode provided along an inner wall of the at least one trench, a dielectric layer provided on the first lower electrode, and an upper electrode provided on the dielectric layer. At least part of the first conductive plug is positioned between an upper surface of the insulating layer and a lowermost portion of the at least one trench.

Abstract: The present invention provides a granular fertilizer with a multilayer coating comprising a first layer containing at least one rapidly biodegradable polymer selected from the group consisting of a rapidly biodegradable aliphatic polyester and a rapidly biodegradable polyurethane compound, and a water-insoluble second layer containing at least one slowly biodegradable polymer selected from the group consisting of a slowly biodegradable cellulose derivative, low molecular weight polyethylene, low molecular weight wax and low molecular weight paraffin or light-degradable resins. The granular fertilizer with a multilayer coating of the present invention is characterized in that it is coated with coating materials having different dissolving-out rates, that dissolving-out of the fertilizer nutrients is controlled, and that the coating does not persist after the nutrients are dissolved out. Accordingly, the granular fertilizer coated with a multilayer of the present invention has less damaging effects on nature.
