Latest Patents

Seokhwan Lee holds a patent for "Atomic layer deposition and etch in a single plasma chamber for fin field effect transistor formation." This patent describes methods and apparatuses for passivating a FinFET semiconductor device and performing a gate etch using integrated atomic layer deposition (ALD) and etch processes. The methods include performing a partial gate etch, depositing a passivation layer on exposed surfaces of semiconductor fins and a gate layer by ALD, and executing a final gate etch to form one or more gate structures of the FinFET semiconductor device. Notably, the etch, deposition, and etch processes are performed in the same plasma chamber, which enhances efficiency. The passivation layer is crucial as it is deposited on the sidewalls of the gate layer to maintain the gate profile during etching.
