IPC: H01L33/48
Filed: 1987-08-10
Abstract: PURPOSE:To form ring-geometry serrate grooves on the surface of an LED substrate for use as a Fresnel lens by a method wherein two photoresist layers different in etch rate are subjected to directional dry etching. CONSTITUTION:A first photoresist 3 is formed into rings on the surface of a substrate 1 mounted with an LED 10 provided with a light-emitting surface 2 and, on the first photoresist 3, a second photoresist 4 is provided by application, again to form rings. For the construction of etch-ready sections 6 to be etched into inclinations, the second photoresist 4 is positioned inside the first photoresist 4. For the construction of etchready sections 5 to be etched into vertical walls, the first photoresist 3 is roughly flush with the second photoresist 4. Photoresists should be selected so that the first photoresist 3 will be higher in etch rate than the second photoresist 4. Directional dry etching is performed from above, whereby the substrate 1 is provided with inclinations 7. This method results in an LED 10 provided with a Fresnel lens 8.
