Tetramethylammonium Hydroxide (TMAH) is a crucial chemical in the semiconductor industry, widely used for photoresist development, silicon wafer etching, and anisotropic wet etching processes. As a highly selective etchant, TMAH enables precise patterning and microstructuring of semiconductor materials, making it essential for fabricating integrated circuits (ICs), microelectromechanical systems (MEMS), and advanced display panels. One of its key advantages is its ability to etch silicon with high accuracy while maintaining minimal damage to surrounding materials, ensuring the integrity of delicate semiconductor structures. Beyond etching, TMAH is also used in developer solutions for photolithography, playing a vital role in removing unexposed photoresists during the semiconductor manufacturing process.

Lithium Iron Phosphate (LiFePO₄ or LFP) cells are a highly reliable and safe type of lithium-ion battery, widely used in electric vehicles, solar energy storage, and backup power systems. Known for their exceptional cycle life, often exceeding 5,000 charge cycles, LFP batteries offer superior thermal stability and minimal risk of overheating or explosion. Unlike traditional lithium-ion chemistries, they do not contain cobalt, making them more environmentally friendly and cost-effective. While they have a slightly lower energy density compared to NMC batteries, their durability, fast charging capability, and ability to operate in extreme temperatures make them a preferred choice for long-term applications.
