摘要:
A method for manufacturing a bump on a semiconductor comprising the steps of: forming metal pad on a portion of a surface of a substrate, forming a barrier metal layer over the surface of the substrate such that the barrier metal layer cover the metal pad, forming a photoresist layer over the barrier metal layer, forming an opening in the photoresist layer to expose a portion of the barrier metal layer overlaying the metal pad, forming a chip bump in the opening, selectively removing the photoresist layer using the bump as a mask, such that residual portions of the photoresist layer remain, and such that portions of the barrier metal layer are exposed, etching the exposed portions of the barrier metal layer using the residual photoresist layer as a mask, and removing the residual photoresist layer.

Disclosed is a multi-air conditioner including: an outdoor unit having a compressor, an outdoor heat exchanger, and an outdoor fan for ventilating the outdoor heat exchanger; a plurality of indoor units each having an electronic expansion valve and an indoor heat exchanger; a distributor for selectively guiding a refrigerant of the outdoor unit into the plurality of indoor units according to an operation condition; a four-way valve for selectively switching a flow direction of the refrigerant flowing through the outdoor heat exchanger; a selective expansion unit for selectively expanding the refrigerant according to the flow direction of the refrigerant; a gas-liquid separator for separating a vapor-phase refrigerant and a liquid-phase refrigerant, from the refrigerant flowing from the outdoor heat exchanger; and a connection tube part having a first connection tube for connecting the four-way valve with a distributor, a second connection tube for connecting an upper portion of the gas-liquid separator with the distributor thereby guiding a vapor-phase refrigerant, and a third connection tube for connecting a lower portion of the gas-liquid separator with the distributor thereby guiding a liquid-phase refrigerant.
摘要:
A blower having a turbo fan is installed in a scroll housing with a cutoff. The cutoff has an inclination angle of approximately 50 to 80°, so that it is possible to draw in an increased amount of air while reducing the flow resistance of air. Accordingly, blowing efficiency is improved while simultaneously reducing the generation of noise and vibration.
摘要:
An automatic accounting processor and method far automatically performing an accounting procedure for transaction data on a real time basis through menu selection and input or a data communication network on a computer system, by standardizing, formulating and compounding a management control business of an enterprise. The automatic accounting processor includes a transmitter/receiver, a display/input unit, a storage unit, a processing unit, and an output unit. The automatic accounting processor and method allows an automatic accounting procedure without an accounting knowledge. Also, an accounting procedure and a balancing operation procedure are performed on a real time basis, by automatically controlling errors generated during the accounting procedure, thereby realizing an effective management control.
