，这一点在雷电模拟器官方版本下载中也有详细论述
但要理解这里面的差异和进步，我们要先弄懂那些少则三五块、多则几十块的「防窥膜」是怎么实现防窥的。
以600mm×600mm面板为例，其面积是12英寸晶圆载板的5.1倍，单片产出芯片数量大幅增加。同时，FOPLP的面积利用率超95%，显著优于传统晶圆级封装的85%，同等面积下面板可多容纳1.64倍芯片。基板面积增大持续降低成本，200mm向300mm过渡节约25%成本，300mm向板级封装过渡更可节约66%成本。
Transforms can be stateless or stateful. A stateless transform is just a function that takes chunks and returns transformed chunks:
