Using Chip Technology To Detect And Prevent Diseases


The overlap between semiconductor technology and medicine is growing, creating the same kinds of economies of scale that have fueled the semiconductor industry for the past five decades. While technology has long held a place in the medical world, the idea that chips can save lives and improve health is a relatively new concept. That effort is gaining steam, too, as more capabilities are add... » read more

Ready For Nanoimprint?


Nanoimprint has been discussed, debated, and hyped since the term was first introduced in 1996. Now, a full 20 years later, it is being taken much more seriously in light of increasing photomask costs and delays in bringing alternatives to market. Nanoimprint lithography is something like a room-temperature UV cure embossing process. The structures are patterned onto a template or mold using... » read more

3D Construction Ahead


One of the interesting features of Photonics West is that it covers the full spectrum, from academic research to industrial research to new products in the commercial exhibits. This range of interrelated ideas was on show in 3D fabrication. At one extreme, the latest research in scanning multi-spot three-photon patterning showed 3D structures 100μm thick with 50nm features. Researchers als... » read more

ReRAM Gains Even More Steam


The prospect of using the latest in finFET processing to enable embedded non-volatile memory (NWM) will be described by a team from TSMC and Tsing Hua University in Taiwan at the IEDM meeting on Dec. 8 in Washington, D.C. Embedded NVM has been the first commercial application of ReRam, with products from Panasonic and Terrazon. Industry leaders agree the creation of NVM as a seamless additio... » read more

ReRAM Gains Steam


Resistive RAM appears to be gaining traction. Once considered a universal memory candidate—a replacement for DRAM, flash and SRAM—ReRAM is carving out a niche between DRAM and storage-class memory. Now the question is how large that niche ultimately becomes and whether other competing technologies rush into that space. [getkc id="94" kc_name="ReRAM"] (known alternately as RRAM), is a typ... » read more

Manufacturing Of Next-Generation Channel Materials


One of the many challenges for the IC developers is to change the channel material to increase transistor mobility. But what about manufacturing? Can LED-style epitaxy be migrated to high-volume silicon manufacturing? “The use of Ge and InGaAs quantum wells is an extension of the current strained Si strategy," said Aaron Thean, vice president of process technologies and director of the log... » read more

Molecular Imprints becomes a virtual reality company


Molecular Imprints was the venture funded imprint equipment start up, that was split up last year when the semiconductor applications were acquired by Canon. Sources tell me that the remaining non-semiconductor portion Molecular Imprints has been acquired by Magic Leap, a virtual reality start up that raised $542M last year in a B round led by Google. Magic Leap has developed a proprietary... » read more

3 Ways To Reload Moore’s Law


The electronics revolution has been enabled because the cost and power per transistor has decreased 30% per year for the last 30 years — a fact usually associated with Moore's Law. This has been accomplished by simply reducing the transistor size while offsetting increased costs of equipment and mask levels, and by increased productivity from improved yield, throughput and wafer size. This... » read more

New Approaches To Imaging For Both Large And Small


Imaging is the common theme for everything at Photonics West this year, and two new ideas caught my attention—a near field very small microscope and a new way of collecting images that separates reflected light from indirect light. IMEC has presented papers about its near field microscope before. This year the research house has reduced it to a product. The idea is to illuminate a object w... » read more

5 Reasons EUV Will Or Won’t Be Used


Digging into this subject, there are five metrics that count in a lithography tool: resolution, throughput, defects, overlay, and reliability. So what does the best data tell us about the current state and realistic prognosis for [gettech id="31045" comment="EUV"]. Semiconductor Engineering posed this question to Matt Colburn, senior manager for patterning research at [getentity id="22306" comm... » read more
