Problems solved by technology

The shape of the micro-stacked insulator needs to be obtained by machining. Although the current machining accuracy is already very high, its surface seems to be very smooth, but due to the huge difference in the mechanical properties of metal and insulating materials, there are micro-convexities on the surface of the metal layer from a microscopic view. Ripples and glitches are inevitable
