The &amp;quot;light source&amp;quot; is either a synchrotron, or an incredible kludge where droplets of tin are vaporized by lasers.  They also produce totally incoherent light, while the ordinary processes use lasers producing coherent light, which focuses better.&lt;p&gt;Deep ultraviolet light source: [1] Little box.&lt;p&gt;Extreme ultraviolet light source: [2] Two floors of equipment.&lt;p&gt;Nobody really wants to go to EUV with the existing sources. The industry hopes for an EUV source that isn&amp;#x27;t insanely expensive, incoherent, dim, and an operational headache. But there&amp;#x27;s nothing better coming along in the near term. Intel and Samsung have chosen to build EUV fabs, to be ready in 2019, maybe. Everybody else is trying hard not to.&lt;p&gt;[1] &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.oxxius.com&amp;#x2F;LUV-series-266nm-280nm-CW-laser&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.oxxius.com&amp;#x2F;LUV-series-266nm-280nm-CW-laser&lt;/a&gt;

For years they were able to sit on fat server margins because of superior fab process and CPU architecture.  Now GF&amp;#x2F;Samsung&amp;#x2F;TSMC is competitive in fab technology and AMD has Zen.  The days of high server margins are coming to an end.</text><parent_chain></parent_chain></comment><story><title>Global Foundries discloses 7nm process detail</title><url>https://www.semiwiki.com/forum/content/6879-exclusive-globalfoundries-discloses-7nm-process-detail.html?utm_content=buffere2e76&amp;utm_medium=social&amp;utm_source=twitter.com&amp;utm_campaign=buffer</url></story>
