Latest Patents

Qiu Hong's latest patents include a groundbreaking process for making a piezoelectric thin film component. This method involves depositing a thin titanium film on a bottom metal layer, allowing parts of the titanium film to remain on the crystal grain boundaries of the bottom metal layer to form seed crystals. A polycrystalline piezoelectric thin film is then formed on the bottom metal layer, promoting the growth of a perovskite crystalline lattice from these seed crystals. Another significant patent details a method of manufacturing piezoelectric thin film components utilizing seed crystals, such as titanium crystals, as a crystal source on a bottom electrode. This process allows for the growth of piezoelectric material crystals using the seed crystals as a nucleus, resulting in a polycrystalline structure with potentially different orientations and grain sizes compared to the bottom electrode. The formation of the piezoelectric thin film may also include a sol-gel film formation process and a metal organic decomposition process, enhancing the quality and properties of the final component.
