The present invention discloses a novel silicon carbide-based lateral PN junction extreme ultraviolet detector with enhanced detection performance based on selective-area ion implantation, including an N-type ohmic contact lower electrode, an N-type substrate and a lightly-doped epitaxial layer which are connected sequentially from bottom to top, where the lightly-doped epitaxial layer is an N-type lightly-doped epitaxial layer or a P-type lightly-doped epitaxial layer; in a case that the lightly-doped epitaxial layer is an N-type or P-type lightly-doped epitaxial layer, a P-type or N-type well region is formed on the surface of the N-type or P-type lightly-doped epitaxial layer through the selective-area ion implantation, a P-type or N-type ohmic contact upper electrode is arranged on the P-type or N-type well region, and the P-type or N-type ohmic contact upper electrode is provided with a metal conductive electrode along its periphery.

A method for recycling silver from a waste IC chip include: heating to disassemble an IC chip, and crushing the IC chip into powders; adding the powders to a nitric acid solution, heating, centrifuging and collecting a first filtrate; adding soluble starch to the first filtrate, where a mass concentration ratio of the soluble starch to Fe in the first filtrate is 5.20-7.30; heating a resulting mixture to 130-175° C. for a first hydrothermal reaction, separating a precipitate from the first hydrothermal reaction and collecting a second filtrate; heating the second filtrate to 160-230° C. for a second hydrothermal reaction, separating a solid from the second hydrothermal reaction and collecting a third filtrate; drying, grinding, and sieving the solid to obtain silver powders; and adding alkali to the third filtrate to form a precipitate of Cu, and separating the precipitate to yield copper hydroxide.
