Latest Patents

Yoojin Kim holds a patent titled "Method and apparatus for providing mask in semiconductor processing." This patent discloses a method for processing a two-layer mask used in the fabrication of semiconductor devices. The method allows for the control of the critical dimension (CD) of the semiconductor device being fabricated. The process involves forming a carbon mask layer and a silicon-containing photoresist layer on the carbon mask. A two-step process is then employed to create openings in the carbon mask layer, which are essential for subsequent device fabrication. The structure is placed in a plasma processing chamber, where an oxygen plasma is used to partially etch the carbon layer. This plasma reacts with silicon in the photoresist to form a hard silicon oxide layer on the surface of the photoresist. Finally, a hydrogen plasma is utilized to complete the etch through the carbon layer with a reduced critical dimension, while minimizing damage to the silicon-containing photoresist layer by limiting the low-frequency RF power.
