Disclosed therein is an air conditioner for a vehicle, which includes an evaporator and a storage tank getting in surface contact with each other, thereby doubling a cold storage effect by directly transferring cold air of the evaporator to the storage tank in a cooling mode, maximizing the cold storage effect because condensate water generated from the surface of the evaporator additionally cools the surface of the storage tank, and effectively enhancing heat-exchanging performance without increasing capacity of the storage tank. The air conditioner further includes heat-exchanging means mounted inside the storage tank so as to enhance the heat exchange performance of a heat carrier more.

An organic inverter and a method of manufacturing the same are provided, which regulates threshold voltages depending on positions when an inverter circuit is manufactured on a substrate using an organic semiconductor. To form a depletion load transistor and an enhancement driver transistor at adjacent positions of the same substrate, the surface of the substrate is selectively treated by positions or selectively applied by self-assembly monolayer treatment. Thus, a D-inverter having a combination of a depletion mode and an enhancement mode is more easily realized than a conventional method using a transistor size effect. Also, the D-inverter can be realized even with the same W/L ratio, thereby increasing integration density. That is, the W/L ratio does not need to be increased to manufacture a depletion load transistor, thereby improving integration density.
