Searching For 3D Metrology
By Mark LaPedus - 19 Mar, 2015 - Comments: 3

In the previous decade, chipmakers made a bold but necessary decision to select the [getkc id="185" kc_name="finFET"] as the next transistor architecture for the IC industry. Over time, though, chipmakers discovered that the finFET would present some challenges in the fab. Deposition, etch and lithography were the obvious hurdles, but chipmakers also saw a big gap in metrology. In fact,... » read more

Manufacturing Bits: Oct. 22

Natural lithography For years, researchers have been exploring the development of nanosphere lithography or natural lithography. Nanosphere lithography makes use of directed self-assembly (DSA) techniques. The process begins with self-assembly of a nanosphere mask onto a substrate. This is followed by deposition of a material through the mask. The University of Paderborn has put a new twis... » read more

LEGO AFM Students from the University College London (UCL), Tsinghua University and Peking University have built an atomic force microscope (AFM) or nanoscope using toy LEGOs. The AFM, dubbed LEGO2NANO, costs less than $500 to make. In contrast, traditional AFMs cost $100,000 or more. The system was made using LEGOs, Arduino controllers, 3D printed parts and consumer electronics. [captio... » read more

Waiting For 3D Metrology
By Mark LaPedus - 18 Apr, 2013 - Comments: 0

By Mark LaPedus Over the years, suppliers of metrology equipment have managed to meet the requirements for conventional planar chips. But tool vendors now find themselves behind in the emerging 3D chip era, prompting the urgent need for a new class of 3D metrology gear. 3D is a catch-all phrase that includes a range of new architectures, such as finFET transistors, 3D NAND and stacked-die ... » read more
