摘要:
A system for selective chemical vapor deposition of polymers onto a substrate. A substrate is provided which comprises a plurality of surface regions, wherein the surface of at least one region provides a more favorable nucleation site for at least one of a polymer or polymer precursor than at least one other region. This may be an intrinsic characteristic of the substrate or may be accomplished through surface treatment of a substrate. The substrate is subjected to chemical vapor deposition of a reactive monomer, producing a polymer coating which is substantially thicker in the regions of favorable nucleation than in the regions of unfavorable nucleation.

A liquid dispenser array structure includes a liquid dispensing channel. A first liquid supply provides a carrier liquid that flows continuously through an outlet of the liquid dispensing channel during a drop dispensing operation. A plurality of liquid dispensers, located on a common substrate, includes a liquid supply channel and a second liquid supply that provides a functional liquid, immiscible in the carrier liquid, to the liquid dispensing channel through the liquid supply channel. A drop formation device, associated with an interface of the liquid supply channel and the liquid dispensing channel, is selectively actuated to form a discrete drop of the functional liquid in the carrier liquid flowing through the liquid dispensing channel.

A drop formation device, associated with an interface of the liquid supply channel and the liquid dispensing channel, is selectively actuated to form discrete drops of the functional liquid in the carrier liquid flowing through the liquid dispensing channel. A receiver conveyance mechanism and the liquid dispenser array structure are positioned relative to each other such that the discrete drops of the functional liquid are applied to a receiver.

A jetting module includes a first substrate, a liquid source, and a second substrate. Portions of the first substrate define a nozzle. The liquid source provides a liquid under pressure sufficient to jet a stream of the liquid through the nozzle. Portions of the second substrate define a filter including a plurality of pores. The filter is positioned between and in fluid communication with the liquid source and the nozzle. The second substrate includes a semi-conductor material.

A printer includes a printhead and a source of fluid. The printhead includes a nozzle. The fluid is under pressure sufficient to eject a column of the fluid through the nozzle. The fluid has a temperature. An asymmetric thermal modulator is associated with the nozzle and includes a structure that transiently lowers the temperature of a first portion of the fluid as the fluid is ejected through the nozzle and a structure that transiently raises the temperature of a second portion of the fluid as the fluid is ejected through the nozzle.
