Abstract:
1. A method of depositing a layer on a substrate, comprising: (a) causing a first relative movement between a substrate comprising a device and one or more reactors, a shadow mask placed between the substrate and the one or more reactors; (b) injecting a source precursor onto the device and the substrate by the one or more reactors responsive to causing the first relative movement; (c) diffusing the injected source precursor into a clearance between the substrate and the shadow mask; (d) causing a second relative movement between the substrate and the one or more reactors; (e) injecting a reactant precursor onto the device and the substrate by the one or more reactors responsive to causing the second relative movement; (f) diffusing the injected reactant precursor to replace or react with the source precursor and deposit a layer of first material on the device and the substrate, the layer of the first material extending into the clearance for a first distance; (g) causing a third relative movement between a substrate and one or more reactors; (h) injecting another source precursor onto the device and the substrate by the one or more reactors responsive to causing the third relative movement; (i) diffusing the other injected source precursor into the clearance between the substrate and the shadow mask; (j) causing a fourth relative movement between the substrate and the one or more reactors; (k) injecting another reactant precursor onto the device and the substrate by the one or more reactors responsive to causing the fourth relative movement; and (l) diffusing the other injected reactant precursor replacing or reacting with the other source precursor to deposit a layer of second material on the device and the substrate, the layer of the second material extending into the clearance for a second distance greater than the first distance.
