Abstract: A production method of a light guide and a stamper, combining anisotropic etching and isotropic etching. First a plurality of microstructures is formed on a back surface and a front surface of the substrate. By electroforming, rear and front stampers are made from the back and front surfaces of the substrate. Light guides are produced using the rear and front stampers. Anisotropic etching is performed on the front surface of the substrate, forming V-shaped, U-shaped or pyramid like microstructures. Isotropic etching is performed on the back surface of the substrate, forming quadratic, bowl like, oval or semicircular microstructures. If a transparent substrate is used, then after finishing the etching of microstructures, a light source, a reflector, a diffusion sheet and a prism sheet are added, simulating a back light module for performing a test of luminosity, uniformity of light intensity and light emission angle, so that optical properties are known before proceeding with inverse-forming of the stampers.

The curved pattern has non-constant widths along a straight line direction. An excimer laser beam source is deployed to project through the photomask on a substrate coated with a polymeric material while the substrate is moving in a direction normal to the straight line direction for the polymeric material to receive laser beam projection with different time period. The polymeric material thus may be etched to different depth to form a three dimensional pattern desired. By projecting and etching the polymeric material two times at different directions or through different photomask patterns, a sphere like or non-sphere like surface of micro array structure may be obtained.

Abstract: The present invention uses a glass to act as a substrate. A stencil layer is patterned on the top surface of the substrate. Successively, a copper layer is deposited over the substrate. Next step is to remove the stencil layer. A negative photoresist layer is formed on the copper layer. A negative photoresist layer is processed using a backside exposure of the resist through the transparent substrate. The backside exposure technique uses the self-aligning, conductive copper layer as a mask. A plurality of trenches are then created in the photoresist layer and a second copper layer is electroplated in the trenches to form the planar coils.
