Front-End (FEOL), Middle-End (MEOL), and Back-End (BEOL) are the three main stages in the semiconductor manufacturing process, each playing a different role in the manufacturing process. The Front-End (FEOL) primarily focuses on the fabrication of transistors; the Middle-End (MEOL) emphasizes the connection of transistors with metal interconnects, serving to…
IntroductionLet’s discuss the aspects of chip design, tapeout, verification, manufacturing, and costs; tapeout is like taking a major exam for chip design.The importance of tapeout lies in its ability to verify whether the chip design is successful; it is a critical step in chip manufacturing, where the finalized design is handed over to the chip … Read more

How are circuit boards made? The production process of PCB boards can be roughly divided into: Printed circuit board—inner layer circuitry—lamination—drilling—plating through holes (first copper)—outer layer circuitry (second copper)—solder mask green paint—text printing—contact processing—shaping and cutting—final inspection and packaging. So there are many devices involved; what equipment does PCB need? Generally, the production of PCB … Read more
