Masahiro Hatakeyama

Masahiro Hatakeyama, a prolific inventor from Tokyo, JP, has made significant contributions to the field of polishing apparatus and substrate polishing methods. With an impressive portfolio of 96 patents, Masahiro Hatakeyama continues to revolutionize the industry with his innovative ideas and designs.

One of his latest patents is for a polishing apparatus of substrate, specifically designed for flattening quadrate substrates. This polishing apparatus features a substrate holding portion that securely holds the quadrate substrate during the polishing process. Notably, the apparatus incorporates an attachment mechanism that attaches a retainer member to the outside of at least one corner of the substrate supporting surface. This design ensures the efficient and effective polishing of quadrate substrates.

In addition to the polishing apparatus, Masahiro Hatakeyama has also patented a method for polishing substrates that include functional chips. This method incorporates an end point sensing element, which allows for precise termination of the polishing process at an appropriate position. By sealing the substrate, functional chip, and end point sensing element with an insulating material, the method enables accurate sensing of the polish's end point while the insulating material is being polished. This innovation ensures that the functional chip remains unaffected during the polishing process.

Masahiro Hatakeyama has had the opportunity to work with esteemed companies in the industry, including Ebara Corporation and Kabushiki Kaisha Toshiba. His collaborations with these organizations have further fueled his creative drive and enabled him to bring his groundbreaking ideas to life.
