A positive resist composition comprising a base polymer comprising recurring units (a) having the structure of an ammonium salt of fluorosulfonic acid having an iodized or brominated aromatic ring, and recurring units (b1) having an acid labile group-substituted carboxyl group and/or recurring units (b2) having an acid labile group-substituted phenolic hydroxyl group exhibits a high sensitivity, high resolution, low edge roughness and dimensional uniformity, and forms a pattern of good profile after exposure and development.
Systems and methods for monitoring one or more characteristics of a substrate
A substrate inspection system is provided to monitor characteristics of a substrate, while the substrate is disposed within (or being transferred into/out of) a processing unit of a liquid dispense substrate processing system. The inspection system is integrated within a liquid dispense substrate processing system and includes one or more optical sensors of a reflectometer (such as a spectrometer or laser-based transceiver) configured to obtain spectral data from a substrate. A controller is coupled to receive the spectral data from the optical sensors(s). The one or more optical sensors (or one or more optical fibers coupled to the rest of the optical sensor hardware) are coupled at locations within the substrate processing system. The controller analyzes the spectral data received from the optical sensors(s) to detect characteristic(s) of the substrate including, but not limited to, film thickness (FT), refractive index changes, and associated critical dimension (CD) changes.
TWO-AXIS SPIN COATING METHOD AND APPARATUS
A modified technology of spin coating which is named Two-Axis spin coating is disclosed. The innovative Two-Axis spin coating apparatus is a rotary device that spins the substrate horizontally the same as conventional spin coaters while the whole horizontal spinning system can be rotated vertically. The vertical rotation of the substrate generates a vertical centrifugal force perpendicular to the surface of the substrate which allows the coating face with an elevated artificial gravity acceleration. The elevation of gravity acceleration adjusts and normalizes the local high and low surface tension stresses on the surface of the coated film. This elevation of gravity also increases the weight of coating elements artificially and obliges the wavy surface convex regions to flow toward the concave areas. The elevation of gravity also obliges the lighter probable air bubbles inside the layer, immediately before the coating surface skinning process, move toward the surface and drain out from the layer. The invention provides a method to level the layer's edge beads, level the coated surface, drain out probable micro sized air bubbles inside the layer and form denser film simultaneously.

METHOD OF COATING A PHOTORESIST AND APPARATUS FOR PERFORMING THE SAME
In a method of coating a photoresist, the photoresist may be provided to an upper surface of a rotating wafer. A hovering solution may be injected to an edge portion of the photoresist under a condition that the hovering solution may be hovered with respect to the edge portion of the photoresist with an air layer being interposed between the hovering solution and the edge portion of the photoresist to limit and/or prevent a bead of the photoresist from being formed on an edge portion of the upper surface of the wafer. Thus, the photoresist having a uniform thickness may be coated on the upper surface of the wafer to improve a yield of a semiconductor device by increasing an effective area of the edge portion of the wafer.
