Latest Patents

Seong-Ju Choi holds a patent for a "Method for forming a thin layer on semiconductor substrates." This invention involves an apparatus and a method that efficiently forms a thin layer on multiple semiconductor substrates. The processing chamber of the apparatus includes a boat that arranges the semiconductor substrates in a vertical direction. A vaporizer is utilized to vaporize a liquid metal precursor into a metal precursor gas. Additionally, a buffer receives a source gas from the vaporizer and increases its pressure to above atmospheric levels. The source gas includes the metal precursor gas, and a first supply pipe connects the buffer to the processing chamber, featuring a valve to control the mass flow rate of the source gas. A second supply pipe connects the vaporizer to a pump, creating a vacuum inside the processing chamber and includes a valve for exhausting a dummy gas during the vaporizer's idling operation.
