Latest Patents

Xing-Fu Zhong's latest patents reflect his dedication to innovation in the microelectronics sector. One of his notable inventions is the development of superplanarizing spin-on carbon materials. This invention provides planarizing and spin-on-carbon (SOC) compositions that fill vias and/or trenches on substrates while ensuring a smooth surface in a single thin layer coating process. The compositions can effectively planarize a wide range of substrates, accommodating vias or trenches from about 20 nm to about 220 nm wide, and depths of up to about 700 nm. This capability stems from the unique properties of low molecular weight polymers used in the materials, coupled with thermally-labile protecting groups and a delayed crosslinking reaction.

Another significant patent involves polyimides as laser release materials for 3-D IC applications. This invention pertains to release layer compositions that facilitate thin wafer handling during the manufacturing of microelectronics. The preferred release layers are derived from a combination of polyamic acid or polyimide in a solvent system, subsequently cured at 250°C to 350°C for a brief period. This process creates polyimide release layers advantageous for temporary bonding processes, which can be laser debonded post-manufacturing.
