Abstract

See full text

A manufacturing method of a diamond porous grinding block based on 3D printing. The manufacturing method includes designing a 3D printing model of a grinding block unit cell with an adjustable porosity according to an internal cooling space for abrasive debris required in a grinding process, importing the 3D printing model of the grinding block unit cell into a MAGICS software, filling a frame of a 3D printing model of a diamond porous grinding block with a plurality of 3D printing models of grinding block unit cells; preparing mixed powder of diamond abrasive particles and an aluminum alloy binder as printing powder, performing 3D printing to the 3D printing model of the diamond porous grinding block by an SLM technology to obtain the diamond porous grinding block. The diamond porous grinding block is configured to form a diamond structure grinding disc for grinding a semiconductor substrate.
