"Let's laugh a little. Let's face it: SPIE is sometimes dry and boring. However, TSMC tried to change the mood. During a presentation, TSMC attempted to convince the audience that EUV is cheaper than double-patterning. In a chart, it proved its point. The trouble: TSMC neglected to add EUV mask costs to the equation, meaning its data was wrong and pointless. It did draw some much needed laughter during the dry event. Thanks for the memories, TSMC."
