Patent ID: 8006637

Claim:
An apparatus for depositing a membrane, the apparatus comprising: a. a liquid precursor source; and b. a chamber, the chamber comprising: i. a midsection capable of supporting a substrate having a first end, a second end, and a plurality of through-channels extending through the substrate from the first end to the second end; ii. an inlet section adjacent to the midsection in contact with the first end of the substrate, wherein the inlet section is in fluid communication with the liquid precursor source and the first end of the substrate, and wherein the inlet section is capable of providing a uniform distribution of a liquid precursor to the first end of the substrate; iii. an outlet section adjacent to and in fluid communication with the second end of the substrate, wherein the outlet section is capable of providing a uniform discharge of a fluid from the second end of the substrate and the resultant removal of the fluid from the chamber; c. a pressurization system coupled to the chamber, wherein the pressurization system provides a pressure differential between the first end and the second end through the plurality of through-channels; and wherein the chamber is oriented vertically such that the inlet section is located at the bottom of the chamber below the midsection and the outlet section is located at the top of the chamber above the midsection.
