The Danger Of Twin Supply Chains


No matter how the ongoing dispute between the United States and China turns out, damage already has been done. It's not the kind of damage that is immediately visible to the outside world. It's more of the long-term, policy-shift kind of problem, which over time will likely prove much worse. Many executives have termed recent sanctions on Huawei and other Chinese companies "China's Sputnik m... » read more

China’s Latest Goal—More DRAMs


China is once again making a concerted effort to get its domestic DRAM industry off the ground. Past efforts have fallen short or failed. This time around, it’s unclear if China will succeed, but the industry should pay close attention here. So why would China want to play a bigger role in the tough and competitive DRAM business? For one thing, the U.S. and China are in the midst of a t... » read more

200mm Cools Off, But Not For Long


After years of acute shortages, 200mm fab capacity is finally loosening up, but the supply/demand picture could soon change with several challenges on the horizon. 200mm fabs are older facilities with more mature processes, although they still churn out a multitude of today’s critical chips, such as analog, MEMS, RF and others. From 2016 to 2018, booming demand for these and other chips ca... » read more

Challenges Grow For 5G Packages And Modules


The shift to 5G wireless networks is driving a need for new IC packages and modules in smartphones and other systems, but this move is turning out to be harder than it looks. For one thing, the IC packages and RF modules for 5G phones are more complex and expensive than today's devices, and that gap will grow significantly in the second phase of 5G. In addition, 5G devices will require an as... » read more

Process Control For Next-Generation Memories


The Internet of Things (IoT), Big Data and Artificial Intelligence (AI) are driving the need for higher speeds and more power-efficient computing. The industry is responding by bringing new memory technologies to the marketplace. Three new types of memory in particular—MRAM (magnetic random access memory), PCRAM (phase change RAM) and ReRAM (resistive RAM)—are emerging as leading candidat... » read more

Electronics Industry Business Cycles Look Promising


Although total electronics industry manufacturing activity is still far from expanding (3/12 is below 1.0), key global electronic industry monthly time series appear to have reached their 3/12 bottoms and now have begun to improve (Chart 1). Currently shipments are still shrinking, but at slowing rates. However real growth will only occur when these 3/12s exceed 1.0. Growth rates vary b... » read more

Creating 2D Compounds


A 2D material, by definition, has no surface dangling bonds. A bulk material with plate-like structure, such as graphite, is composed of thin layers with a weakly bonded cleavage plane between. What this means is a monolayer of graphite will seek to satisfy its exposed dangling bonds by absorbing other materials. A monolayer of graphene, in contrast, is energetically complete without a secon... » read more

Process Modeling Exploration for 8 nm Half-Pitch Interconnects


In this paper, we simulate eSADP, eSAQP and iSAOP patterning options to enable fabrication of 8 nm Half-Pitch (HP) interconnects. We investigate the impact of process variations and patterning sensitivities on pitch walking and resistance performance. The overall yield is also calculated for eight line CDs as well as M2-via-M1 via segment resistance and compared for all options. Process sensiti... » read more

Wide Band Gap—The Revolution In Power Semiconductors


New government regulations and industry standards are leading companies to adopt wide bandgap (WBG) power solutions, both to reduce their carbon footprint and to meet increasing demand for higher power systems aimed at electric vehicles, renewable energy, datacenters, and other markets. The automotive industry is one of the biggest markets driving demand for WBG power devices. The European U... » read more

A Novel Design Method of Highly Efficient Saturated Power Amplifier Based On Self-Generated Harmonic Currents


A novel design method without requiring the special harmonic termination circuit for a highly efficient power amplifier (PA) is proposed. The proposed PA is driven into saturated operation, from the linear to knee region, by adjusting the only fundamental load, and the saturated operation induces self-generated harmonic currents. The current and voltage waveforms can be shaped easily by the har... » read more
