Provided are an apparatus and method for treating wafers using a supercritical fluid. The wafer treatment apparatus includes a plurality of chambers; a first supply supplying a first fluid in a supercritical state; a second supply supplying a mixture of the first fluid and a second fluid; a plurality of first and second valves; and a controller selecting a first chamber of the plurality of chambers for wafer treatment to control the open/closed state of each of the plurality of first valves so that the first fluid can be supplied only to the first chamber of the plurality of chambers and selecting a second chamber of the plurality of chambers to control the open/closed state of each of the plurality of second valves so that the mixture of the first fluid and a second fluid can be supplied only to the second chamber of the plurality of chambers. The wafer treatment method involves performing a predetermined treatment such as etching, cleaning or drying on wafers within only one of the plurality of chambers, followed by wafer treatment on the succeeding chamber, and thus allowing for sequential wafer treatment within each of the plurality of chambers.

Substrate treatment equipment includes a wet treatment apparatus for treating a substrate with a solution (liquid), a drying (treatment) apparatus discrete from the wet treatment apparatus and for drying the substrate using a supercritical fluid, and a transfer device. The substrate is extracted by the transfer device from the wet treatment apparatus after the substrate has been treated and the substrate is transferred by the device while wet to the dry treatment apparatus. To this end, various elements/methods may be used to keep the substrate wet or wet the substrate. In any case, the substrate is prevented from drying naturally, i.e., from air-drying, as the substrate is being transferred from the wet treatment apparatus to the drying apparatus. Thus, equipment and method prevent defects such as water spots and the leaning of fine structures on the substrate.

A method of forming fine pitch hardmask patterns includes forming a hardmask layer on a substrate and forming a plurality of first mask patterns on the hardmask layer. A buffer layer is formed on the plurality of first mask patterns, and has an upper surface defining recesses between adjacent first mask patterns. Second mask patterns are formed within the recesses formed in the upper surface of the buffer layer. The buffer layer is partially removed to expose upper surfaces of the plurality of first mask patterns, and the buffer layer is then partially removed using the first mask patterns and the second mask patterns as an etch mask to expose the hardmask layer between the first mask pattern and the second mask pattern. Using the first mask patterns and the second mask patterns as an etch mask, the hardmask layer is etched to form hardmask patterns.

摘要:
A cleaning solution for an immersion photolithography system according to example embodiments may include an ether-based solvent, an alcohol-based solvent, and a semi-aqueous-based solvent. In the immersion photolithography system, a plurality of wafers coated with photoresist films may be exposed pursuant to an immersion photolithography process using an immersion fluid. The area contacted by the immersion fluid during the exposure process may accumulate contaminants. Accordingly, the area contacted by the immersion fluid during the exposure process may be washed with the cleaning solution according to example embodiments so as to reduce or prevent defects in the immersion photolithography system.
