NOVELTY - The method comprises: providing (S31) a substrate with an interface hydrophilic modified polymer layer; creating a hydrophilic zone on the interface hydrophilic modified polymer layer using one of light, gas and liquid with the polymer's hydrophilicity conversion property; coating the substrate with a liquid material to condense liquid microlenses in the hydrophilic zone; and curing the liquid microlenses to form microlenses. The creating step comprises creating a periodic arrangement of the hydrophilic zone on the interface hydrophilic modified polymer layer using a mask.    USE - The method is useful for fabricating a mircolens array (claimed) that is useful for optoelectronic devices such as light-emitting device, photodetector, solar cell, optical fiber communication systems and micro-optical-electromechanical system.    ADVANTAGE - The method is capable of economically fabricating the mirco-lens array in a rapid and accurate manner with high efficiency at low temperature and without etch transfer process.    DETAILED DESCRIPTION - The method comprises: providing (S31)a substrate with an interface hydrophilic modified polymer layer; creating a hydrophilic zone on the interface hydrophilic modified polymer layer using one of light, gas and liquid with the polymer's hydrophilicity conversion property; coating the substrate with a liquid material to condense liquid microlenses in the hydrophilic zone; and curing the liquid microlenses to form microlenses. The step of creating a hydrophilic zone on the interface hydrophilic modified polymer layer comprises: creating a periodic arrangement of the hydrophilic zone on the interface hydrophilic modified polymer layer using a mask. The step of coating the substrate with the liquid material comprises: dipping the substrate in and out of the liquid material at a constant velocity. The step of curing the liquid microlenses comprises: pulling a curvature of the liquid microlenses to a desirable angle with an external electric field; and curing the liquid microlenses with UV light. The light comprises UV light. The method is performed at room temperature. The method further comprises: placing (S32) the mask over the interface hydrophilic modified polymer layer; modifying (S33) the interface hydrophilic modified polymer layer using UV/ozone for creating the hydrophilic zone on the interface hydrophilic modified polymer layer; removing (S34) the mask; and immersing (S35) the substrate in the liquid material and removing the substrate from the liquid material to condense the liquid microlenses. An INDEPENDENT CLAIM is included for a mircolens array.    DESCRIPTION OF DRAWING(S) - The diagram shows a flow chart of a fabrication method of a mirco-lens array.
