A carrier structure for supporting a substrate when being processed by passing the carrier through a meniscus formed by upper and lower proximity heads is described. A method of manufacturing the carrier further described. The method includes forming a composite frame having a carbon fiber core, a top sheet, a bottom sheet, a layer of aramid fabric between the top sheet and the core and a second layer of aramid fabric between the bottom sheet and the core. The top sheet and the bottom are each formed from a polymer material. The method further includes forming an opening sized for receiving a substrate and providing a plurality of support pins extending into the opening for supporting the substrate within the opening. The opening is formed slightly larger than the substrate such that a gap exists between the substrate and the opening.

1. A method of manufacturing a carrier for supporting a substrate processed by passing the carrier through a meniscus formed by a proximity head, the method comprising: forming a composite frame of a carbon fiber core, a top sheet, a bottom sheet, a layer of aramid fabric between the top sheet and the carbon fiber core and a second layer of aramid fabric between the bottom sheet and the carbon fiber core, the top sheet and the bottom sheet being formed from a polymer material, the frame having an opening sized for receiving a substrate, the frame also having a plurality of support pins extending into the opening in a parallel orientation relative to a surface of the top sheet and the bottom sheet, the plurality of supporting pins defined for supporting the substrate within the opening, the opening being slightly larger than the substrate such that a gap exists between the substrate and the opening. 2. The method of claim 1, wherein the frame is formed with a slight arch so that when the frame is under the load of carrying a substrate, the frame substantially flattens out for minimal vertical displacement from a plane. 3. The method of claim 1, wherein the carbon fiber core has an epoxy matrix. 4. The method of claim 3, wherein the carbon fiber is further formed by adding least one layer of uni-directional pre-impregnated carbon fiber material above and below the carbon fiber core. 5. The method of claim 4, wherein carbon fibers of the unidirectional pre-impregnated carbon fiber material are oriented perpendicular to left and right edges of the carrier, the left and right edges extending in a direction of travel of the carrier. 6. The method of claim 1, wherein the top sheet and bottom sheet are formed of polyvinylidene fluoride. 7. The method of claim 1, wherein the aramid fabric is pre-impregnated with epoxy. 8. The method of claim 1, further comprising molding the carbon fiber with thickened left and right edges to provide increased mechanical stability, the left and right edges extending in a direction of travel of the carrier. 9. The method of claim 1, wherein the carrier further comprises a filler material formed from thermoplastic powder that is sintered or binded during a thermal cycling treatment during manufacture of the carrier. 10. The method of claim 1, wherein the support pins are formed from one of polyvinylidene fluoride or polyetheretherketone. 11. The method of claim 1, wherein the composite frame is shaped to have six sides. 12. The method of claim 11, wherein of the six sides, a first side and a second side are parallel to each other and have thickened edges, third and fourth sides and fifth and sixth sides are respectively defined between the first side and the second side, wherein third, fourth, fifth and sixth sides are angled away from a perpendicular direction defined from the first side or the second side. 13. A method of making a carrier for use in preparing a substrate, comprising: forming body comprising a core material having a first side and a second side, the core material having a layer of thermoplastic formed over both the first side and second side of the core material;forming an opening in the body, the opening being sized to receive the substrate and defined with a plurality of pins, the plurality of pins extending into the opening in a parallel orientation relative to a surface of the first and second sides of the body;applying a thermal curing cycle to the body to minimize residual stresses and reduce non-flatness characteristics of the body;applying a pressure over a top surface and edges of the thermoplastic layers to ensure confinement of the body; andmachining the body to define the carrier, the machining being configured to define dimensions of the opening and outer size parameters of the carrier. 14. The method of making a carrier for use in preparing a substrate as recited in claim 13, wherein the machining further includes, shaping specific portions of the layer of thermoplastic. 15. The method of making a carrier for use in preparing a substrate as recited in claim 13, shaping parts of the body to define the edges of the body. 16. The method of making a carrier for use in preparing a substrate as recited in claim 13, wherein the thermal curing cycle uses a temperature that is up to a melting point of the thermoplastic layers of the first side and the second side. 17. The method of making a carrier for use in preparing a substrate as recited in claim 13, further comprising: modifying a surface roughness of the layer of thermoplastic to obtain a desired hydrophobicity. 18. The method of making a carrier for use in preparing a substrate as recited in claim 13, wherein the body is shaped to have six sides. 19. The method of making a carrier for use in preparing a substrate as recited in claim 18, wherein of the six sides, a first side and a second side are parallel to each other and have thickened edges, third and fourth sides and fifth and sixth sides are respectively defined between the first side and the second side, wherein third, fourth, fifth and sixth sides are angled away from a perpendicular direction defined from the first side or the second side.
