Copper Electrodeposition For Fan-Out Wafer-Level Packaging


As integrated circuit designers bring more sophisticated chip functionality into smaller spaces, heterogeneous integration, including 3D stacking of devices, becomes an increasingly useful and cost-effective way of mixing and connecting various functional technologies. One of the heterogeneous integration platforms gaining increased acceptance is high density fan-out wafer-level packaging (FOWL... » read more

Generalized Class-E Power Amplifier With Shunt Capacitance And Shunt Filter


This paper presents a generalized analysis of the Class-E power amplifier (PA) with a shunt capacitance and a shunt filter, leading to a revelation of a unique design flexibility that can be exploited either to extend the maximum operating frequency of the PA or to allow the use of larger active devices with higher power handling capability. The proposed PA fulfills zero voltage switching (ZVS)... » read more

Complementary FETs At the recent 2020 Symposia on VLSI Technology and Circuits, Imec presented a paper on a 3D complementary field-effect transistor (CFET) made on 300mm wafers. As a demonstration vehicle, Imec showed a CFET based on a 14nm process. Ideally, though, CFETs are next-generation transistors that are targeted for the 1nm node in the future. On the transistor front, chipmaker... » read more

Week In Review: Manufacturing, Test


Market research After years of falling demand, the PC market is back. The second quarter of 2020 ended well for the traditional PC market, including desktops, notebooks, and workstations. Global PC shipments jumped 11.2% year-over-year reaching a total of 72.3 million units, according to IDC. As restrictions around the world tightened in the first few weeks of the quarter, demand for notebo... » read more

Fast Arm-based supercomputer Japan has taken the lead in the supercomputer race, jumping ahead of the U.S. But China continues to make its presence felt in the arena. Fugaku, an ARM-based supercomputer jointly developed by Japan’s Riken and Fujitsu, is now ranked the world’s fastest supercomputer in the 55th TOP500 list. Fugaku turned in a high performance Linpack (HPL) result of 415.5... » read more

Fan-out gas sensors At the recent IEEE Electronic Components and Technology Conference (ECTC), the University of California at Los Angeles (UCLA) and the Indian Institute of Science presented a paper on the development of a wearable MEMS gas sensor device based on a flexible wafer-level fan-out packaging technology. Researchers have demonstrated a gas sensor device or a personal environment... » read more

China Speeds Up Advanced Chip Development


China is accelerating its efforts to advance its domestic semiconductor industry, amid ongoing trade tensions with the West, in hopes of becoming more self-sufficient. The country is still behind in IC technology and is nowhere close to being self-reliant, but it is making noticeable progress. Until recently, China’s domestic chipmakers were stuck with mature foundry processes with no pres... » read more
