DRAM Scaling Challenges Grow


DRAM makers are pushing into the next phase of scaling, but they are facing several challenges as the memory technology approaches its physical limit. DRAM is used for main memory in systems, and today’s most advanced devices are based on roughly 18nm to 15nm processes. The physical limit for DRAM is somewhere around 10nm. There are efforts in R&D to extend the technology, and ultimate... » read more

Planning For Panel-Level Fan-out


Several companies are developing or ramping up panel-level fan-out packaging as a way to reduce the cost of advanced packaging. Wafer-level fan-out is one of several advanced packaging types where a package can incorporate dies, MEMS and passives in an IC package. This approach has been in production for years, and is produced in a round wafer format in 200mm or 300mm wafer sizes. Fan-out... » read more

World’s lightest foam Lawrence Livermore National Laboratory (LLNL) has developed what researchers say is the world’s lightest gold foam. LLNL has devised gold aerogel foam. The foam is light enough where it could be carried on the back of tiny insects. Applications for the technology include electronics, catalysis, sensors and energy conversion and storage. An aerogel is based on a ... » read more

Power beams The U.S. Naval Research Laboratory and PowerLight Technologies have demonstrated the ability to transmit energy using a long-range, free-space power beaming system. The system is being developed as part of the Power Transmitted Over Laser (PTROL) project. The system consists of two 13-foot-high towers. One tower consists of 2-kilowatt laser transmitter. The other tower consist o... » read more

Chipmakers The IC industry once had several leading-edge vendors that invested and built new fabs. But over time, the field has narrowed due to soaring costs and a dwindling customer base. In 1994, the share of semiconductor industry capital spending held by the top five companies was 25%, according to IC Insights. This meant that a number of companies invested and built new fabs during the... » read more

Nanoliter measurements The National Institute of Standards and Technology (NIST) has developed an optofluidic measurement system that can measure the flow of liquids at the nanoliter scale. Targeted for the field of microfluidics, the system can measure the flow of liquids as small as 10 billionths of a liter per minute. A nanoliter (nL) is one billionth of a liter. A liter is 33.814 ounces... » read more

Chipmakers China has created a new $29 billion fund to help advance its semiconductor sector, according to reports from Bloomberg and others. Here's another report. The The U.S. and China are in the midst of a trade war. This has prompted China to accelerate its efforts to become more self-sufficient in semiconductor design and production. This includes DRAMs as well as logic/foundry. -----... » read more

Searching for dark energy The first tests have been conducted on a new cosmic cartography system that will soon search for dark energy and galaxies in the universe. The system, called the Dark Energy Spectroscopic Instrument (DESI), is a complex unit with 5,000 fiber-optic eyes. The DESI system is mounted on top of the 4-meter Mayall Telescope at the Kitt Peak National Observatory in Ariz... » read more
