But, we still need a few more rounds of photolithography to build a transistor.

但是，我们仍然需要多轮光刻来制造晶体管。

Yep, there are a lot of special chemicals in photolithography, each with a very specific function!

是的，光刻有很多特殊的化学品，每一种都有非常特殊的功能！

As photolithography techniques improved, the size of transistors shrunk, allowing for greater densities.

随着光刻技术的改进，晶体管的尺寸缩小，从而允许更高的密度。

Timing is super important in photolithography in order to control things like doping diffusion and etch depth.

为了控制诸如掺杂扩散和蚀刻深度之类的事情，时间在光刻中非常重要。

First, we’re bumping into limits on how fine we can make features on a photomask and it’s resultant wafer due to the wavelengths of light used in photolithography.

首先，由于光刻中使用的光的波长，我们在光掩模和最终晶圆上制作特征的精细程度遇到了限制。

In photolithography, we take electromagnetic radiation, or what we tend to call light, and we use it to shrink down some of that circuitry, so that we could cram more of it into a really small space.

在光刻法里，我们使用电磁辐射，或者，我们更倾向于叫光，我们用它来缩小电路的一些部分，这样我们可以在一个非常小的空间里塞进更多的电路。
