▎ 摘　　要

NOVELTY - Preparing graphene electric core pole by semiconductor etching comprises taking pole lug, locating the upper and lower ends of wave structures on the polar lug and coating with graphene. USE - The method is useful for preparing graphene electric core pole by semiconductor etching. ADVANTAGE - The method eliminates the damage of the elements caused by the plasma and improves productivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for fabricating graphene electric core pole, comprising (i) removing the unprocessed pole lug and diffusing the chemical etching solution to the surface of the pole lug; (ii) allowing to stand the chemical etching solution and the pole lug and reacting; (iii) diffusing the reaction of diffusion of the product surface of the solution and discharging the solution; and (iv) controlling the rate of the above steps.
