The Impact Of Metal Gate Recess Profile On Transistor Resistance And Capacitance
By Pradeep Nanja - 18 May, 2023 - Comments: 0

In logic devices such as finFETs (field-effect transistors), metal gate parasitic capacitance can negatively impact electrical performance. One way to reduce this parasitic capacitance is to optimize the metal gate recess dimensions. However, there are limits to reducing this capacitance if you simply remove more of the metal material, since this can modify capacitance unexpectedly through chan... » read more

How Low Can You Go? Pushing The Limits Of Transistors
By Synopsys - 08 Mar, 2023 - Comments: 0

Deep low voltage enablement of embedded memories and logic libraries to achieve extreme low power: Rising demand for cutting-edge mobile, IoT, and wearable devices, along with high compute demands for AI and 5G/6G communications, has driven the need for lower power systems-on-chip (SoCs). This is not only a concern for a device’s power consumption when active (dynamic power), but also when... » read more

Improved graphene-base heterojunction transistor with different collector semiconductors for high-frequency applications
By Technical Paper Link - 10 Apr, 2022 - Comments: 0

New research paper from TU Dresden & others. Abstract "A new kind of transistor device with a graphene monolayer embedded between two n-typesilicon layers is fabricated and characterized. The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. The transit time for e... » read more

Transition-Metal Nitride Halide Dielectrics for Transition-Metal Dichalcogenide Transistors
By Technical Paper Link - 20 Dec, 2021 - Comments: 0

Abstract "Using first-principles calculations, we investigate six transition-metal nitride halides (TMNHs): HfNBr, HfNCl, TiNBr, TiNCl, ZrNBr, and ZrNCl as potential van der Waals (vdW) dielectrics for transition metal dichalcogenide (TMD) channel transistors. We calculate the exfoliation energies and bulk phonon energies and find that the six TMNHs are exfoliable and thermodynamically stabl... » read more

Power/Performance Bits: March 31
By Jesse Allen - 31 Mar, 2020 - Comments: 0

Tellurium transistors Researchers from Purdue University, Washington University in St Louis, University of Texas at Dallas, and Michigan Technological University propose the rare earth element tellurium as a potential material for ultra-small transistors. Encapsulated in a nanotube made of boron nitride, tellurium helps build a field-effect transistor with a diameter of two nanometers. �... » read more

The 7nm Pileup
By Ed Sperling - 04 Apr, 2019 - Comments: 1

The number of 7nm designs is exploding. Cadence alone reports 80 new 7nm chips under design. So why now, and what does this all mean? First of all, 7nm appears to be the next 28nm. It's a major node, and it intersects with a number of broad trends that are happening across the industry, all of which involve AI in one way or another. The big question now is how many of them will survive long ... » read more

Top Stories For 2018
By Brian Bailey - 20 Dec, 2018 - Comments: 0

Each year, I look back to see what articles people like to read. The first thing that has amazed me each year at Semiconductor Engineering is that what should be a strong bias towards articles published early in the year never seems to play out. The same is true this year. More than half of the top articles were published after July. The second thing that remains constant is that people love... » read more
