摘要: An embodiment of the current disclosure includes a method of providing a substrate, forming a polysilicon layer over the substrate, forming a first photoresist layer on the polysislicon layer, creating a first pattern on the first photoresistlayer, wherein some portions of the polysilicon layer are covered by the first photoresist layer and some portions of the polysilicon layer are not covered by the first photoresist layer, implanting ions into the portions of the polysilicon layer that are not covered by the first photoresist layer, removing the first photoresist layer from the polysilicon layer, forming a second photoresist layer on the polysilicon layer, creating a second pattern on the second photoresistlayer, and implanting ions into the portions of the polysilicon layer that are not covered by the second photoresist layer, removing the second photoresist layer from the polysilicon layer, and removing portions of the polysilicon layer using an etchant.
