Amidst the turbulent backdrop of Spain's Civil War, Marius Torres i Perena, a Catalan poet, captured a moment of tranquility on November 6, 1910. Meanwhile, in the realm of technology, photolithography emerged as a game-changer. This advanced technique, first introduced in the late 19th century for Gothic forms applied to furniture, metal work, and decoration, found new life in the 20th century. By the 1950s, it became the cornerstone of MEMS (Micro-Electro-Mechanical Systems) production, revolutionizing industries from aeronautics to healthcare. Maclure & Macdonald's advertisement proudly showcased their photolithography expertise, enabling the fabrication of intricate silicon-based integrated circuits and wafer production. Today, visual inspection of photomasks undergoes rigorous scrutiny to ensure the precision and quality of each photolithographic process, maintaining the technological edge in an ever-evolving world.
