Title: Xu Ma - Innovator in Semiconductor Manufacturing

Xu Ma is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of semiconductor manufacturing, particularly through his innovative patent. His work focuses on improving the reliability and efficiency of high-voltage semiconductor devices.

Latest Patents

Xu Ma holds a patent for a method of manufacturing a semiconductor device. This method addresses the challenge of removing hard mask residues that remain along the boundaries between high-voltage device regions and STI structures after a dry etch process. By partially reducing the thickness of the exposed portions of the STI structures adjacent to the high-voltage device region, the method ensures that residues are sufficiently exposed. Consequently, when the underlying pad oxide corresponding to the high-voltage device region is removed in a subsequent process, the substrate's exposed surface becomes uniform with a smooth and clear border. This innovation prevents the emergence of sharp corners at the border of the gate oxide that is subsequently grown on the substrate, thereby enhancing the morphological quality and reliability of the fabricated high-voltage semiconductor device.
