摘要: An imaging structure such as a mask or reticle may be fabricated using a patterning layer on an imaging layer. The patterning layer may have substantially different etch properties than the imaging layer. A first etch process may be selective of the patterning layer with respect to a resist layer. A second etch process may be selective of the imaging layer with respect to the patterning layer.

摘要: An alternating phase shift mask may be formed using a dry undercut etch. The dry undercut etch reduces problems associated with wet etching of quartz or glass masks. In addition, the use of the dry undercut etch enables image balancing between the zero and pi apertures. This approach is not limited by specific optical proximity corrected design patterns or chromium layer thickness.

摘要: Design rules are described for a phase alternating shift mask for minimum chrome width and maximum segment length, where an embodiment employs during a cleaning process of the mask a megasonic power of 50 Watts at 1 MHz, and 30 Watts at 3 MHz. Some embodiments utilize an dry etch Carbon Tetrafluoride and Dioxygen based process. Other embodiments are described and claimed.
