A: Chip stacking is done by placing multiple chips vertically on top of each other, and by connecting pins between chips through copper wires to form a more powerful chip. At present, chip stacking technology has been widely used in smart phones, computers and network equipment and other fields.

The advantages of chip stacking technology are obvious. First, it can layer multiple chips on top of each other, reducing the chip area and thus reducing manufacturing costs. Second, chip stacking technology can greatly improve the performance of the chip, because it can integrate the functions of multiple chips in one chip, thus strengthening the computing, storage and communication capabilities of the chip. In addition, in the fields of image processing icon and machine learning, chip stacking technology can strengthen the image analysis and processing capabilities of the chip, and speed up the training speed of machine learning icon.
