Selective deposition of a dielectric on a self-assembled monolayer-adsorbed metal
Abstract:
Methods and apparatuses to selectively deposit a dielectric on a self-assembled monolayer (“SAM”) adsorbed metal are described. A wafer includes a device having a first electrode. A first self-assembled monolayer is deposited on the wafer covering the first electrode. Next, a portion of the first self-assembled monolayer is removed to expose the first electrode. The first self-assembled monolayer includes a hydrophobic layer. Further, second self-assembled monolayer is deposited on the first electrode. The second self-assembled monolayer includes a hydrophilic layer. Next, an insulating layer is deposited on the second self-assembled monolayer. Further, self-aligned contacts to one or more second electrodes of the device are formed.
