HMB stack

Summary

Thermo-compression bonding is used in heterogeneous 3D packaging technology – this attach method was applied to the assembly of large (12-stack and 16-stack) high bandwidth memory (HBM) die, with significant bandwidth and power improvements over traditional microbump attach.

Introduction

The rapid growth of heterogeneous… Read More

scaled metal resistance

Summary
Design Technology Co-Optimization (DTCO) analysis was pursued for library cell PPA estimates for gate-all-around (GAA) devices and new metallurgy options.  The cell design and process recommendations are a bit surprising.

Introduction
During the “golden years” of silicon technology evolution that applied Dennard… Read More

A Quick TSMC 2019 Tech Symposium Overview

A Quick TSMC 2019 Tech Symposium Overview
by Daniel Nenni on 04-26-2019 at 7:00 am

This year TSMC did a FinFET victory lap with the success of 16nm, 12nm, 10nm, and 7nm. It really is well deserved. Even though TSMC credits the ecosystem and customers, I credit TSMC and their relationship with Apple since it has pushed us all much harder than ever before. TSMC CEO C.C. Wei summed it up nicely in his keynote: Innovation,… Read More
