A plastic package used to carry packaging wafers. We call it wafer carrier tape

In the news of semiconductors, we always mention the wafer factories marked by size, such as 8-inch or 12-inch wafer factories. So, what is the so-called wafer? Which part is 8 inches? What is the difficulty of making large-size wafers? The following is a step-by-step introduction to the most important foundation of Semiconductors – what is “wafer”.

Wafers are the basis for manufacturing all kinds of computer chips. We can compare chip manufacturing to building a house with Lego blocks, and complete our desired shape (that is, all kinds of chips) by stacking layer after layer. However, if there is no good foundation, the built house will be crooked, which is not what you want. In order to make a perfect house, you need a stable base plate. For chip manufacturing, this substrate is the wafer to be described next.—wafer carrier tape
