Used PVA Delta 8 #293671097 for sale

PVA Delta 8 is a well-known photoresist system developed by the SYNTAX Corporation. Photoresists are specialty chemicals used in a wide range of lithographic, etching, and deposition processes during the fabrication of integrated circuits and other electronic components. Delta 8 is a high-performance liquid-based photoresist which offers excellent lithographic resolution, precise alignment, and uniform image transfer fidelity. It offers deep UV and near-UV exposure, making it ideal for lithographic applications. It features low surface roughness and resists most chemical solvents and etchants, as well as heat and ultraviolet radiation. Due to its excellent durability and chemical resistance properties, PVA Delta 8 is widely used in the production of complex electronic structures and devices such as photodetectors, transistors, and MOSFETs (Metal-Oxide Semiconductor Field-Effect Transistors). The chemical composition of Delta 8 consists of a combination of several subunits, which provide the final photoresist with superior properties. First, the base component is polyvinyl alcohol (PVA), which has excellent solubility in many organic solvents, and provides excellent adhesion to various substrates. Second, several sensitizers are added to optimally absorb the UV light during exposure and facilitate the penetrating of the resist into the substrate surface. Third, a resin binder is included to provide the necessary cohesion properties to enable its use in photolithography. Finally, several crosslinkers are used to provide the necessary chemical resistance. In addition, this photoresist has a high etch selectivity, which means it can be used to etch with other photoresists, as well as with metals such as aluminum, copper, tin, and silver. This makes it possible to achieve very fine features, as well as a high aspect ratio during the etching process. Overall, PVA Delta 8 is an extremely versatile and highly reliable photoresist system that is well-suited for many different lithographic and etching processes. It has superior resolution, fidelity, adhesion, and chemical resistance, making it a desirable choice for the production of complex device components.
