Marangoni style, cold hot IPA vapor dryers

Chemical process, rinsing, and drying can be performed in a single module enabling fabs to meet the requirements of sub-90-nm technology nodes.

While 90-nm technologies ramping up to full production, the ability to perform a particle-neutral and water spot–free dry during wafer surface preparation has been identified as a technology enabler. Such capability is especially important for devices with high-aspect-ratio attributes such as vias, contacts, deep trenches, and poly-Si features, where water spots form easily at hydrophilic/hydrophobic interfaces. Spots that are large enough to overlap more than one die will result in a definite yield loss, and even smaller water spots can cause killer defects, high leakage currents, critical-dimension variations, and film adhesion problems, all of which also may contribute to yield loss.

The ability to achieve those ambitious surface-preparation goals hinges on the ability to combine process steps in order to minimize the number of air-liquid interfaces that the wafer experiences, which will, in turn, reduce the number of surface defects. It will also be important to combine chemical process steps with rinsing and drying operations in a single process vessel, especially in the case of hydrofluoric acid (HF)–last cleaning processes, which are becoming more widespread with the use of sub-30-Å gate oxides. Performing a true HF-last process in a single vessel will help to reduce exposure to the oxidizing ambient, achieve ideal surface passivation (i.e., hydrogen-terminated silicon), and minimize particle addition to the sensitive hydrophobic surface.

Advanced Processing Equipment Technology has been preparing for the 300mm under 0.090 technology’s surface to be even more perfect. The most adequate usage of Le Chatellier’s principle during the rinsing and drying procedure enables the finest control of wafer surface as no system could have done before.
	IPA vapor dryers Kimmon design and precision manufacturing produce IPA vapor dryers with rapid recovery times. This eliminates a common source of contamination - water spots formed from longer recovery times allowing wafers to dry before IPA vapor is generated.
	DI water heaters This design eliminates DI water contamination from water heater system induced impurities such as metallic ions, organic compounds, and microbes.		HTC+ Oxide free surface up to 72 hours queue time ARTICLES
	External torches The hydrogen is ignited by the halogen lamp heating a non-doped silicon target to over 850 degrees centigrade. This ignition process prevents devitrification of the quartz chamber and assures no particulate contamination into the process tube.
