Method Of Fabricating Mask |
摘要 |
A method for fabricating an extreme ultraviolet (EUV) mask includes providing a low thermal expansion material (LTEM) layer. A reflective multiple-layer (ML) is deposited over the LTEM layer. A flowable-photosensitive-absorption-layer (FPhAL) is spin coated over the reflective ML. The FPhAL is patterned by a lithography process to form a patterned absorption layer. |

1. A method for fabricating an extreme ultraviolet (EUV) mask, the method comprising:
providing a low thermal expansion material (LTEM) layer; forming a reflective multiple-layer (ML) over the LTEM layer; forming a conductive layer over an opposite surface of the LTEM layer; spin-coating a flowable-photosensitive-absorption-layer (FPhAL) over the reflective ML; and patterning the FPhAL by a lithography process to form a patterned absorption layer having a first region and a second region, wherein the FPhAL is removed in the first region and remains in the second region. |
