Selective deposition using differential surface charging

A method includes extracting electrons from a remote electron source to negatively charge upper surfaces of a patterned layer with the electrons, and extracting positive ions from a remote ion source to selectively deposit a material on the upper surfaces by attracting the positive ions to the electrons of the upper surfaces. The upper surfaces may be negatively charged by concurrently applying a positive bias at the patterned layer and applying source power with a lower power level to generate plasma. The material may be selectively deposited by concurrently applying a negative bias at the patterned layer and applying source power with a higher power level to plasma. An extraction grid may separate the patterned layer from the plasma. The extraction grid may be electrically floating or coupled to a ground potential during either of the electron extraction step or the ion extraction step.
