Abstract
The present invention can form lenses with a small radius of curvature by using surface tension due to heat and gravity and by directing the spherical surfaces of lenses downward during thermal processing at a constant temperature. In addition, the present invention can control a distance between lenses in a step of forming lens patterns since the molten lens material during the thermal processing is not extended along the surface of the highest interlayer. Thus, thick lenses with a small radius of curvature can be easily obtained by gravity and a distance between lenses can accurately be controlled.
