What is left is are rows of oblong dies. Around and around it goes--design, photolithography, etching--in a repeated cycle. Every procedure must be repeated more than 20 times, with a different circuit design overlaid on the chip each time. Only after more than 50 days of the most precise etching can a single glittering eight-inch wafer of several hundred memory chips be successfully completed.
定義圖形、曝光、蝕刻、固相，周而復始，每一道手續都要重複二十多次，每次在晶片上刻下不同的電路圖，經過五十多天的精雕細琢，一片攜帶著數百粒記憶體晶片、閃動著神秘折射光的八吋晶圓，才算大功告成。
