    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.

    摘要: A wet etching device used in manufacturing a semiconductor device includes a power source, a transmission device for transmitting power from the power source, and a roller for reversing top and bottom positions of a wafer placed in a processing bath using power from the power source transmitted by the transmission device. Here, the initial top and bottom positions of the wafer during loading are reversed before unloading. Accordingly, the entire surface of the wafer spends an equal amount of time in the processing bath containing a chemical solution and can thus be etched uniformly.

    摘要: A gate is formed on a device formation region of a semiconductor substrate, and source and drain regions are formed in the device formation region of the semiconductor substrate adjacent respective sides of the gate. The gate is formed to include a gate dielectric layer, a gate conductive layer and sidewall spacers located at respective sidewalls of the gate conductive layer. An etch stop layer is formed over the source region, the drain region and the sidewall spacers of the gate to obtain an intermediate structure, and a planarized first interlayer insulating film is formed over a surface of the intermediate structure. The first insulating layer is dry etched until the etch stop layer over the source region, the drain region and the sidewall spacers is exposed to form self-aligned contact holes in the first interlayer insulating over the source region and the drain region, respectively. The etch stop layer is then wet etched to remove the etch stop layer over the source region, the drain region and the sidewall spacers, and respective contact pads are formed by filling the self-aligned contact holes with conductive polysilicon.

    摘要: A wafer cassette through which a sonic wave is evenly transferred to a substrate in a quartz bath, and a cleaning system adopting the wafer cassette are provided. In the wafer cassette, a hole for evenly transferring the sonic wave to the substrate is formed. The cleaning system includes a vibration plate for generating a sonic wave, placed at the lowest portion of the cleaning system, a sink placed on the vibration plate, a quartz bath placed in the sink and spaced from the bottom of the sink, in which a wafer cassette is placed, a plurality of water supplies for supplying a cleaning solution, placed in the bottom of the quartz bath and a water drain for draining the cleaning solution overflown from the quartz bath, placed on the bottom of the sink, opposite to the water supplies, wherein the vibration plate is placed between the water drain and the water supplies. As a result, the oscillation frequency does not deviate from the setting value and air bubbles are not formed at the lower portion of the quartz bath, so that the irregular reflection of the sonic wave is restricted. Thus, the sonic wave is evenly transferred to the wafer, thereby enhancing the capability of removing the particles from the substrate.
