摘要:
A semiconductor wafer cleaning apparatus and method uses only one inner bath for chemical solution and de-ionized water cleaning, and includes a marangoni dryer for cleaning and drying semiconductor wafers. The apparatus includes a loading unit loaded with a cassette holding wafers; a moving mechanism for extracting the wafers from the cassette and moving the wafers into a loader; an inner bath for cleaning the wafers with a chemical solution or de-ionized water; a marangoni dryer including a hood, for moving the wafers from the loader into the bath, to be sealed to the bath; and a knife for supporting the wafers loaded into the bath at a lower portion thereof and moving the wafers up and down. Since the marangoni dryer is adhered to the bath during drying, the wafers are not affected by laminar flow or exhaustion and water marks do not occur thereon.

There is provided a wet-etching facility for manufacturing semiconductor devices, wherein the etching process is performed for a wafer with its used surface facing downward so that the by-products from the etching process are completely removed from the etching groove of the wafer by gravity, and the impurities on the back side of the wafer are sank down, and are not touched to the used surface of the other wafer thereby producing good quality of wafers. The wet-etching facility for manufacturing semiconductor devices comprises a bath containing an amount of chemical; a chemical supply part for supplying an amount of chemical to the bath; a chemical discharge part for discharging the chemical inside the bath to the outside; a wafer guide holding and fixing a wafer with its used surface facing downward, and placing the wafer into a chemical; a transfer robot for loading and unloading the wafer into the wafer guide; and a chemical spray part for spraying the chemical at a high pressure such that the chemical flows along a surface of the wafer.

A wafer dryer for drying a wafer includes a chamber and a support adapted to support the wafer in the chamber. A spray nozzle is disposed in the chamber. A source gas supply tank is in fluid communication with the spray nozzle. At least one heater is operable to heat the chamber and the source gas supply tank. A pumping line is in fluid communication with the chamber. Drive means are operable to rotate the chamber and the spray nozzle. A method for drying a wafer using a wafer dryer including a chamber and a revolving spray nozzle includes the steps of: loading the wafer in the chamber; reducing the pressure in the chamber in which the wafer is loaded to a near vacuum state; creating a temperature controlled atmosphere in the pressure-reduced chamber to quicken drying of the wafer; and spraying the source gas on the wafer while rotating the chamber and the revolving spray nozzle in opposite directions in the pressure-reduced temperature controlled atmosphere.

A circulation system for supplying one or more chemicals, or mixtures thereof, includes a chemical tank containing the chemical. A chemical supply line is connected at one end to the chemical tank, through which the chemical from the chemical tank is supplied to one of a processing section, for performing a specific semiconductor device fabrication process, and a bypass section, for collecting the chemical while the processing section is idle. A supply nozzle, connected to another end of the chemical supply line, is movable between the processing section and the bypass section, such that the supply nozzle is selectively oriented above one of the processing section and the bypass section. A primary chemical re-circulation line connects the processing section and the chemical tank, and a chemical bypass line connects the bypass section and a portion of the primary chemical re-circulation line.

A method for etching a layer of a microelectronic structure includes the steps of masking the layer to be etched so that predetermined portions of the layer are exposed, and providing an etching gas. An additional gas is also provided wherein the additional gas generates a compound having a carbene structure when exposed to a plasma discharge. A plasma of the etching gas and the additional gas is generated to thereby etch the exposed portions of the layer and to form the compound having a carbene structure. A polymer can thus be formed from the compound having the carbene structure on the sidewalls of the etched portions of the layer. Accordingly, the profile of the etched layer can be improved.

A multi-chamber system of an etching facility for manufacturing semiconductor devices occupies a minimum amount of floor space in a cleanroom by installing a plurality of processing chambers in multi-layers and in parallel along a transfer path situated between the processing chambers. The multi-layers number 2 to 5, and the transfer path can be rectangular in shape and need only be slightly wider than the diameter of a wafer. The total width of the multi-chamber system is the sum of the width of one processing chamber plus the width of the transfer path.
