What he means by the phrase "stick close" is that the process dimension must be at the absolute minimum. Thus it is possible to pile up more than 20 layers on a glossy chip of only 2mm in length by 1mm in width by 0.5mm in height. Each layer, in turn, has hundreds of densely packed circuits etched into it.
「要黏」，指的是線距極端貼近，因此可以在小小一片長寬高各約二公釐、一公釐、0.5 公釐、光滑如鏡的晶片上，疊床架屋地，反覆堆疊出二十幾層立體空間，每一層還密密麻麻刻蝕著數百條線路。
