Wet soluble lithography |
摘要 |
A system to form a wet soluble lithography layer on a semiconductor substrate includes providing the substrate, depositing a first layer comprising a first material on the substrate, and depositing a second layer comprising a second material on the substrate. In an embodiment, the first material comprises a different composition than the second material and one of the first layer and the second layer includes silicon. |

1. A method of forming a wet soluble lithography layer on a substrate, the method comprising:
providing the substrate; depositing a first layer comprising a first material on the substrate, the first layer includes silicon; depositing a second layer comprising a second material over the first layer, wherein the first material comprises a different composition than the second material; after depositing the second layer comprising the second material over the first layer, performing an implantation process on the substrate; and performing one of a thermal treatment and a light treatment after performing the implantation process, wherein the one of the thermal treatment and the light treatment changes the solubility of the first layer. |
