BEOL Integration For The 1.5nm Node And Beyond


As we approach the 1.5nm node and beyond, new BEOL device integration challenges will be presented. These challenges include the need for smaller metal pitches, along with support for new process flows. Process modifications to improve RC performance, reduce edge placement error, and enable challenging manufacturing processes will all be required. To address these challenges, we investigated th... » read more

Yield Enhancement By Virtual Fabrication


This paper provides an example of yield enhancement using virtual fabrication. A 6 transistors based static random access memory example on 7nm node technology was used in this case study. Yield loss caused by via contact-metal edge placement error was modeled and analyzed. The results show that yield can be enhanced from 48.4% to 99.0% through process window optimization and improved specifica... » read more

Synopsys' Ron Lowman considers the increase in specialized AI IP in SoCs, including the different aspects within AI classifications, markets that are driving its growth, key SoC design challenges, and nurturing SoC designs beyond integration. Siemens' Joe Hupcey III finds that the only way to be completely sure that RISC-V RTL is free of any natural or malicious surprises is to apply exhaust... » read more

Week In Review: Manufacturing, Test


Chipmakers, OEMs Intel continues to build more fabs. First, the company announced fabs in Arizona and then Ohio. Now, Intel plans to invest up to €80 billion in the European Union over the next decade. As part of the effort, Intel plans to build two semiconductor fabs in Magdeburg, Germany. Construction is expected to begin in the first half of 2023 and production planned to come online in 2... » read more

Accelerating Semiconductor Process Development Using Virtual Design Of Experiments


Design of Experiments (DOE) are a powerful concept in semiconductor engineering research and development. DOEs are sets of experiments used to explore the sensitivity of experimental variables and their effect on final device performance. A well-designed DOE can help an engineer achieve a targeted semiconductor device performance using a limited number of experimental wafer runs. However, in se... » read more

Cadence's Paul McLellan looks at open and generic PDKs that can be used by researchers and in education... » read more

Blog Review: Feb. 23


Synopsys' Varun Agrawal looks at four new technologies have emerged to support the demands on 5G networks and applications, the challenges in validating all of those technologies together, and what's needed to perform end-to-end testing effectively for 5G O-RAN SoCs. Siemens EDA's Ray Salemi points to how FPGA retargeting could help address supply chain difficulties and some of the challenge... » read more

A Sub-1 Hz Resonance Frequency Resonator Enabled By Multi-Step Tuning For Micro-Seismometer


We propose a sub-1 Hz resonance frequency MEMS resonator that can be used for seismometers. The low resonance frequency is achieved by an electrically tunable spring with an ultra-small spring constant. Generally, it is difficult to electrically fine-tune the resonance frequency at a near-zero spring constant because the frequency shift per voltage will diverge at the limit of zero spring const... » read more
