NOVELTY - The apparatus comprises a work piece support, a relative motion device, a flexible dispensing tube having a support end and a dispensing end, and additional flexible tubes each of which is secured to the tube support. The dispensing end comprises a tracking feature sized and shaped to mechanically track the physical work piece path defined by the textured surface of the work piece. The support end is coupled to the relative motion device through a tube support. The relative motion device is configured to cause relative motion of the dispensing end of the tube.    USE - The apparatus is useful for dispensing a material containing a liquid to a textured surface of a semiconductor work piece such as silicon wafer to form a solar cell, where the workpiece textures include grooves, discrete and spaced apart pits.    ADVANTAGE - The apparatus is capable of precisely and rapidly dispensing the material to a textured surface of the workpiece with high viscosity without distortions, clogging of the tube, additional tracking feature such as external protrusions and the need to rotate the support end of the tube relative to the work piece, and ensures retention of the fluid in the groove by capillarity.    DETAILED DESCRIPTION - The apparatus comprises a work piece support, a relative motion device, a flexible dispensing tube having a support end and a dispensing end, and additional flexible tubes each of which is secured to the tube support. The dispensing end comprises a tracking feature sized and shaped to mechanically track the physical work piece path defined by the textured surface of the work piece. The support end is coupled to the relative motion device through a tube support. The relative motion device is configured to cause relative motion of the dispensing end of the tube as compared to the work piece support along a physical unconstrained dispensing end path. The flexible dispensing tube is chosen such that upon engagement of the tracking feature with a physical work piece path of a textured surface of a work piece supported by the support and actuation of the relative motion device. The dispensing end of the tube mechanically tracks the physical work piece path. The tracking feature comprises a protrusion at an end of a cross-sectional extent of the tube. The physical work piece path has a characteristic minimum width. The tracking feature has a characteristic width that is less than the physical work piece path characteristic minimum width. The flexible dispensing tube has a maximum cross-sectional extent of less than 10 times the physical work piece path characteristic width. The flexible tube is chosen to permit the dispensing end of the tube to mechanically track the physical work piece path despite an error between the physical work piece path and the physical unconstrained dispensing end path. The flexible tube comprises a material consisting of a polymer, polyimide, glass, quartz, metal and stainless steel. The work piece support comprises a fixture that maintains two work pieces fixed relative to each other so that a physical work piece path of each are collinear. The tube has a non-circular cross-section at its dispensing end. The protrusion comprises a wear resistant material, and a magnetically attractive material. The flexible tube has a long axis and a lateral extent perpendicular to the long axis. The tracking feature has a lateral extent that is less than the lateral extent of the tube. The tracking feature comprises an extended rib parallel to an axis of the flexible tube along the outside of the tube. INDEPENDENT CLAIMS are included for:    (1) a patterned work piece such as a semiconductor article; and    (2) a method of providing a material containing a liquid to a textured surface of a semiconductor work piece.
