Silicon wafers are the carriers of most chips. But a piece of silicon wafer hides many unknown details, such as: What are the crystal orientations of silicon wafers? How many positioning flats are there? How is the positioning flats positioned? What is the difference between the positioning flat and Read More

Why do we need to polish the wafer so smoothly?The final fate of the wafer is to be cut into chips (die), packaged in a dark box, with only a few pins exposed. The chip will look at the threshold, resistance, current value, and voltage value, but no one cares about its appearance. In the process, we Read More

1. Definition and function of Dummy WaferDummy Wafer is a wafer specially used to fill machine equipment during wafer manufacturing. It is usually not used in actual production and will not be sold directly as a finished product. Its main function is to meet the specific requirements or constraints Read More

Recently, a chat robot called "ChatGPT" has become famous in the semiconductor industry. This AI program, launched by the artificial intelligence laboratory Open AI at the end of November last year, received more than 1 million registrations within 5 days of its launch, and exceeded 100 million by t Read More

Why do some wafers have no chips on the outer ring, while some wafer circuits spread the entire silicon wafer, and there will be incomplete chips on the outer ring of the wafer? Friends who are familiar with the semiconductor manufacturing process know that before the chip is cut and packaged, all t Read More
