Abstract
An elastomeric stamp is used to deposit material on a non-planar substrate. A vacuum mold is used to deform the elastomeric stamp and pressure is applied to transfer material from the stamp to the substrate. By decreasing the vacuum applied by the vacuum mold, the elasticity of the stamp may be used to apply this pressure. Pressure also may be applied by applying a force to the substrate and/or the stamp. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer.
