Abstract: A yellow light photolithographic process and an electroplating process are performed multiple times to produce copper plated layers on the aluminum nitride (AlN) substrate. The copper plated layers are plated in sequence into a stack structure with each layer having reduced length. The parameters of the yellow light photolithographic process can be adjusted, such that each copper plated layer is formed horizontally for a predetermined length into a stack structure of step layers tapering off upward, while a predetermined angle is formed by the tangent line passing through edges of the respective step layers, and the surface of the AlN substrate. An adhesion layer, a copper seed layer, a first copper plated layer, a second copper plated layer, a third copper plated layer, and a nickel plated layer are formed in sequence on the AlN substrate, to form a metalized circuit of multi-layer stack.

Abstract: A measurement, calibration and compensation system for machine tool includes a first positioning base; two first speckle image sensors for sensing speckle positions of an object holding unit at a first XY plane and a first XZ plane of the first positioning base before and after the machine tool is started for machining; a second positioning base; two second speckle image sensors for sensing speckle positions of a cutter holding unit at a second XY plane and a second YZ plane of the second positioning base before and after the machine tool is started for machining. Thus, the thermal expansion at all axes of the machine tool can be measured in a simplified and low-cost way, and the absolute positioning coordinates of all axes of the machine tool can be calibrated in real time to avoid reduced positioning accuracy due to the thermal expansion of the multi-axis machine tool.
