What it is

The Semitool 270 S is a single-wafer spin rinse dryer (SRD) used in semiconductor manufacturing.[1][2][3][4]

The Semitool 270 S is a specific model of spin rinse dryer produced by the equipment manufacturer Semitool.[1][2][3][4]

How it works

General reference — not yet source-verified

During the rinse cycle, deionized water is dispensed onto the spinning wafer to remove any remaining chemical residues from the preceding wet process.

In the drying cycle, the wafer is spun at a high rotational speed; centrifugal force flings the water off the wafer surface, and a flow of heated nitrogen gas is typically introduced to promote evaporation and prevent watermarks.

Where it fits in the process flow

General reference — not yet source-verified

Upstream steps include wet cleaning baths (such as RCA clean, piranha etch, or dilute HF treatments) or wet etch steps, after which the wafer must be rinsed and dried before proceeding to subsequent thermal, deposition, or lithography processes.

Downstream from the spin rinse dryer, the wafer moves to a dry environment for inspection, metrology, or the next process step, because any residual moisture can cause defects or process issues.

Applications

General reference — not yet source-verified

The machine is used for wafers processed in wet stations that require a clean, dry surface free of water spots and chemical residue before subsequent processing.

Frequently asked questions

What is the primary function of a spin rinse dryer?General reference — not yet source-verified

The primary function is to rinse off chemical residues from wafers after wet processing and then dry them using high-speed centrifugal force and heated gas, leaving the surface clean and moisture-free.

How does the drying mechanism work?General reference — not yet source-verified

Drying is achieved by spinning the wafers at high speeds to centrifugally remove bulk liquid, followed by a flow of heated nitrogen or filtered air that evaporates residual moisture. The combination ensures complete drying without leaving spots or streaks.

What types of wet processes typically precede a spin rinse dryer?General reference — not yet source-verified

Common preceding steps include acid etching, alkaline cleaning, solvent rinses, and oxide stripping. The spin rinse dryer is used to remove the chemical bath residues and prepare the wafers for further processing.

How is contamination control maintained during operation?General reference — not yet source-verified

Contamination control is maintained by using filtered air or inert gases, employing chemically resistant materials in the chamber, and often incorporating HEPA filtration. The closed-loop design minimizes exposure to ambient particulates and ensures the wafers remain in a clean environment throughout the cycle.
