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.
The rapid growth of heterogeneous… Read More
Walking across a carpet can generate up to 35,000 volts of static charge, which is tens of thousands of times higher than the operating voltages of most integrated circuits. When charge build up from static electricity is exposed to the pins of an IC, the electrostatic discharge (ESD) protection network on the chip is intended to… Read More
In RF designs Low Noise Amplifiers (LNA) play a critical role in system operation. They simultaneously need to be extremely sensitive and noise free, yet also must be able to withstand strong signal input without distortion. LNA designers often struggle to meet device performance specifications. Their task is further complicated… Read More
The electrostatic discharge that occurs in lightening, as seen in the picture below, can cause serious damage to the objects on the ground. Over centuries mankind has devised ways, such as lighting rods and arresters, to deflect the energy so it is dissipated harmlessly. The same drama plays out on modern semiconductors due to … Read More
Lurking inside of every Mosfet is a parasitic bipolar junction transistor (BJT). Of course, in normal circuit operation the BJT does not play a role in the device operation. Accordingly, SPICE models for Mosfets do not behave well when the BJT is triggered. However, these models work just fine for most purposes. The one important… Read More
The TSMC OIP Forum was very upbeat this year and now we know why. It wasn’t long ago that some media outlets and a competitor said 7nm would not be a popular node because it is too expensive blah blah blah. People inside the fabless semiconductor ecosystem however know otherwise. As I have said before, 7nm will be another strong node … Read More
In the wake of TSMC’s recent Open Innovation Platform event, I spoke to Frank Ferro, Senior Director of Product Management at Rambus. His presentation on advanced memory interfaces for high-performance systems helped to shed some light on the evolution of system memory for leading edge applications. System implementers now… Read More
Machine learning is transforming how information processing works and what it can accomplish. The push to design hardware and networks to support machine learning applications is affecting every aspect of the semiconductor industry. In a video recently published by Synopsys, Navraj Nandra, Sr. Director of Marketing, takes… Read More
Calling all ASIC designers working on High-Bandwidth Memory (HBM) access architectures in high-performance computing (HPC), networking, deep learning, virtual reality, gaming, cloud computing and data center applications. You won’t want to miss this upcoming webinar focused on system integration aspects of a HBM2 ASIC… Read More
Dual in-line memory modules (DIMM’s ) with double data rate synchronous dynamic random access memory (DDR SDRAM) have been around since before we were worried about Y2K. Over the intervening years this format for provisioning memory has evolved from supporting DDR around 1995, to DDR1 in 2000, DDR2 in 2003, DDR4 in 2007 and DDR4… Read More
