The gas mixture can be used to treat high aspect ratio (HAR) structures arranged on a surface of a substrate. A surface of the substrate may be spin rinsed using a first rinsing liquid. The first rinsing liquid is spun off from the surface of the substrate. The gas mixture is directed onto the surface of the substrate after the first rinsing liquid is dispensed.

Abstract

The present invention relates to gas delivery systems and methods suitable for repairing or preventing stiction of high aspect ratio structures on semiconductor substrates. The gas delivery systems and methods deliver a mixture of a hydrogen halide, vapourised solvent and carrier gas to a substrate through a heated supply line (201), to avoid formation of droplets during transit of the gas mixture. The gas mixture supply line is preferably held within a conduit (202) which includes a purge gas supply line (204), which allows any hydrogen halide leaking through the gas mixture supply line (201) to be carried away by a flow of purge gas within the conduit. In such embodiments, the purge gas is also preferably heated, and used as a means of heating the dispensing outlet of the gas mixture supply line.

Abstract

A device for processing wafer-shaped articles comprises a closed process chamber that provides a gas-tight enclosure. A rotary chuck is located within the closed process chamber. A heater is positioned relative to the chuck so as to heat a wafer shaped article held on the chuck from one side only and without contacting the wafer shaped article. The heater emits radiation having a maximum intensity in a wavelength range from 390 nm to 550 nm. At least one first liquid dispenser is positioned relative to the chuck so as to dispense a process liquid onto a side of a wafer shaped article that is opposite the side of the wafer-shaped article facing the heater.

At least two alternative liquid supply paths are provided downstream of the pressure regulator and upstream of an outlet of the liquid dispenser. Each supply path is equipped with a respective shutoff valve and provides a respectively different pressure drop to the treatment liquid.

Abstract

The harmful effects of accumulating droplets of process liquid on the outer surface of a dispense nozzle are prevented by equipping an apparatus for process wafer-shaped articles with a blow-off block that blows the droplets off the nozzle outer surface before they can coalesce and drop in an uncontrolled manner onto the work piece. The nozzle preferably has a polished and tapered outer surface to aid in blowing off any accumulated droplets of process liquid from the outer surface.

Abstract

A method and device for treating a wafer-shaped article utilizes a novel clamping mechanism, which permits wafer shift to be performed with reduced wear to the chuck pins. A wafer is rotated on a spin chuck that has a plurality of pins positioned at a periphery of the wafer shaped article. The pins each have a head portion which, in a service position, extends radially inwardly of and above the wafer. Gas is supplied onto a surface of the wafer facing the spin chuck at a flow rate sufficient to displace the wafer upwardly into contact with the head portions of the pins. This serves to clamp the wafer against the head portions of the pins. However, the pins contact the wafer only on upwardly oriented wafer surfaces and the wafer is supported from below solely by the gas flow.
