The present application relates to a wafer processing device and a wafer processing method. The wafer processing device includes: a spraying unit configured to spray a photoresist-removing solution to remove a photoresist; and a heating unit mounted to the spraying unit and configured to heat the photoresist-removing solution to a preset temperature. According to the wafer processing device and wafer processing method of the present application, the photoresist-removing solution is heated to a preset temperature, so that the photoresist-removing solution dissolves the photoresist more rapidly and thoroughly. Therefore, the photoresist may be removed from a surface of the wafer more thoroughly, and further a yield of the wafer is increased.

A composition comprising a) a quaternary trialkylalkanolamine hydroxide and b) at least one diamine as component b), which is selected from the group consisting of 1-amino-4-methylpiperazine, 1,2-diaminopropane and mixtures thereof.

In this invention use of silicone hard-coated polycarbonate (SHC-PC) as direct photo definable, thermally, chemically and optically stable polymer that can be patterned using conventional microfabrication and drying etching process is reported. As a result of the increased resistance to thermal and chemical deformations and flow of the silicone hard-coated polycarbonate (SHC-PC), it has been shown for the first time that the illustrated process herein to be compatible with a variety of conventional thin film deposition, micro and nano fabrication approaches such as metal evaporation, photoresist deposition/developing and electroplating that are typically incompatible to polycarbonate. As such high optical clarity surfaces with ultra-hydrophobic-hydrophilic properties with well-defined micro and nano patterned surface features of high surface roughness were fabricated with high fidelity.

A tile system for covering a surface. The tile system comprises a first tile assembly connected to a second tile assembly by a connector. Each tile assembly comprises a first tile stacked on a second tile, the first tile and the second tile joined to a reinforcing material disposed therebetween. The connector comprises a first component and a second component that is complementary to the first component. The first component is mounted to the first tile assembly, and the second component is mounted to the second tile assembly.

A method for making a conductive film includes the steps of: depositing a conductive metal film on a substrate to form a metal-coated substrate; depositing a fiber pattern on the conductive metal film of the metal-coated substrate to form a masked substrate, the fiber pattern defining protected metal and exposed metal of the conductive metal film; removing the exposed metal from the conductive metal film of the masked substrate to form a protected conductive film; and removing the fiber pattern from the protected conductive film to expose the protected metal and provide a metal pattern on the substrate. An annealing step con be employed after depositing the fiber pattern to increase the surface area of contact between the fiber pattern and the conductive metal film.

In systems and methods for removing a photoresist film off of a wafer, the wafer is moved into a bath of a process liquid in a process tank. The process liquid removes the photoresist film from the wafer. The process liquid is pumped from the process tank to a filter assembly and moved through filter media to filter out solids from the process liquid, and the filtered process liquid is returned to the process tank. A scraper scrapes the filter media to prevent clogging of the filter media by accumulated solids.

The present disclosure relates to the technical field of semiconductors, and provides a method of processing a photoresist layer, and a photoresist layer. The method of processing a photoresist layer includes: forming a photoresist layer on a target layer, where the photoresist layer includes a first part close to the target layer and a second part away from the target layer; performing first exposure processing on the photoresist layer, and forming an exposure image in the first part of the photoresist layer; processing the second part of the photoresist layer by using a first process, such that the second part forms a third part, where a photosensitivity of the third part is higher than that of the first part; and stripping the third part.
