A convective self-assembly method is used to deposit uni-sized polystyrene microspheres onto patterned silicon wafer with rectangular microgrooves in this research. The micorspheres are driven toward the patherned grooves of different widths and form two or three-dimensional close-packed structures. Processing variables include temperature, particle size (D), width of groove (W), and depth of groove (H). in this experiment, the best deposition temperature is 45�C. When the ratio of D/W is 0.7415, double-layered zigzag structure exists in the groove. An in=plane structure is not resulted because W D. If w D and , a coplanar structure exists in the groove but when D>H, the double-layered zigzag structure appears again to replace the coplanar structure. When the width of groove continues to increase, the coplanar structure is also favorable because more space allows for microspheres to modulate their arrangement.
