A modeling framework to accurately predict heat dissipation in the chip’s back-end-of-line

Longread

As dimensional scaling continues, the heating of the interconnects in the chip’s <a href="/en/expertise/cmos-advanced/compute/beol">back-end-of-line (BEOL)</a> has become a growing concern, as it can compromise the chip’s reliability.

Imec presents a modeling framework that accurately predicts heat dissipation in advanced BEOL structures, considering the coupling with the logic cells in the front-end-of-line (FEOL) and boundary conditions from packaging technologies.

This article discusses the model and its added value. Valuable insights are presented, such as the dominant contribution of low-k dielectrics and via layers to the BEOL’s thermal resistance.

Mitigating the thermal bottleneck in advanced interconnects 

Imec’s Zsolt Tökei discusses the latest outcome of imec's research on binary and ternary alloys for advanced interconnect metallization schemes with Silicon Semiconductor’s Phil Alsop.

Imec highlights the potential of backside power delivery for high-performance computing and evaluates options for backside connectivity

Research update

Some major chip manufacturers recently announced the introduction of a backside power delivery network (BSPDN) in their logic roadmap.

In this article, imec, in collaboration with Arm, presents a design-technology co-optimization (DTCO) of one specific implementation of a BSPDN, where nTSVs and buried power rails are used for backside routing. They show how the potential of this BSPDN scheme can be fully harvested in a high-performance compute context.

In addition, they introduce alternative options for backside connectivity at the standard cell level, observing the largest scaling potential for a direct backside connectivity scheme.

Molecular interface engineering: a pathway to scalable manufacturing

Metal halide perovskites show great promise for next-generation photovoltaic cells. However, commercialization requires industry-compatible processing techniques to address stability issues.

The largest efficiency losses and instability of perovskite solar cells are reported at the interfaces between the perovskite absorber and charge transport layers.

In this article, dr. Tom Aernouts presents an ammonium salt treatment to enhance two critical interfaces, creating highly efficient, stable, and scalable perovskite cells.

GaN HEMTs and InP HBTs: integration on a Si platform and co-integration with CMOS components

With the advent of next generation 5G and 6G, telecom operators are pushing up the frequencies of the wireless signals.

While GaN high-electron mobility transistors (HEMTs) show promises for 28/39GHz operation, InP heterojunction bipolar transistors (HBTs) are expected to excel at 100GHz and beyond.

In this article, progress is reported in upscaling GaN HEMTs and InP HBTs to a silicon platform and in co-integrating them with CMOS components – requirements for next-gen high-capacity wireless communication.
