Etching Photoresist Negative at Lindy Wesley blog

Etching Photoresist Negative. In using a negative photoresist, the mask must have a negative image of the pattern to be produced. The critical role of photoresists in semiconductor fabrication. Figure 15 illustrates the steps in etching a thin. My earlier setup worked just fine which included: One of the biggest advantages of a negative photoresist is the fact that it tends to be more durable and resistant to the etching process. I seem to be having issues getting my new pcb etching setup to work. Printing negative artwork on a parchment paper. Photoresists are fundamental to modern semiconductor. The unexposed photoresist is then removed, revealing the copper that needs to be etched away. Conversely, negative photoresist becomes hardened when exposed to uv light, making the exposed areas insoluble. Based photoresists tend to have low density and need to have enough thickness to effectively protect the underlying substrate from etching and ion.
