As any semiconductor process advances to the next generation or “node”, a sticky point is how to achieve the required higher resolution. As noted in another article , multipatterning (the required use of repeated patterning steps for a particular feature) has been practiced already for many years, and many have… Read More
EUV lithography is widely perceived to be the obvious choice to replace DUV lithography due to the shorter wavelength(s) used. However, there’s a devil in the details, or a catch if you will.
Electrons have the last word
The resist exposure is completed by the release of electrons following the absorption of the EUV photon.… Read More
Semiconductor equipment vendor ranking, which didn’t change much between 2016 and 2017, is undergoing a makeover, as Lam Research, ASML, and Tokyo Electron (TEL) are switching places and top-ranked Applied Materials is getting closer to losing its number one ranking.
Since the 1990s, Applied Materials has been the market leader… Read More
At SEMICON West I attended the imec technology forum, multiple Tech Spot presentations and conducted a number of interviews relevant to advanced lithography and EUV. In this article I will summarize what I learned plus make some comments on the outlook for EUV.… Read More
