Defect Mitigation And Characterization In Silicon Hardmask Materials


From SPIE Digital Library: In this study, metal contaminants, liquid particle count and on-wafer defects of Si- HMs and filtration removal rates are monitored to determine the effect of filter type, pore size, media morphology, and cleanliness on filtration performance. 5-nm PTFE NTD2 filter having proprietary surface treatment used in this study shows lowest defect count.

Chip Board Interaction Analysis Of 22nm FD-SOI Technology In WLP


Recently, Wafer Level Packaging (WLP) has been in high demand, especially in mobile device applications as a path to enable miniaturization while maintaining good electrical performance. The relatively inexpensive package cost and simplified supply chain are encouraging other industries to adapt WLP capabilities for radio frequency (RF), communications/sensing (mmWave) and automotive applicatio... » read more

Hunting For Open Defects In Advanced Packages


Catching all defects in chip packaging is becoming more difficult, requiring a mix of electrical tests, metrology screening, and various types of inspection. And the more critical the application for these chips, the greater the effort and the cost. Latent open defects continue to be the bane of test, quality, and reliability engineering. Open defects in packages occur at the chip-to-substra... » read more

Blog Review: March 17


Synopsys' Chris Clark considers the growing number of automotive sensors and the cost/performance tradeoffs between edge computing capability, sensor fusion, sensor degradation, monitoring, and the maintenance of the software over the lifespan of a vehicle. Cadence's Paul McLellan checks out how the process of loading the bootstrap into memory has changed over the years, from hand-entered on... » read more

Manufacturing Bits: March 16


Tripping up neural networks For years, Russia has been an active area in R&D. In one example, Russia's Skolkovo Institute of Science and Technology (Skoltech) has demonstrated how certain patterns can cause neural networks to make mistakes in recognizing images. Leveraging the theory behind this research, Skoltech can design defenses for pattern recognition systems that are vulnerable t... » read more

Power/Performance Bits: March 16


Adaptable neural nets Neural networks go through two phases: training, when weights are set based on a dataset, and inference, when new information is assessed based on those weights. But researchers at MIT, Institute of Science and Technology Austria, and Vienna University of Technology propose a new type of neural network that can learn during inference and adjust its underlying equations to... » read more

The Benefits Of Curvilinear Shapes On Photomasks


Do you have four minutes to hear why companies like Micron Technology think that curvilinear shapes on photomasks are an advantage? In a short video, Ezequiel Russell, Senior Director of Mask Technology at Micron Technology shows how curvilinear shapes can increase process windows for advanced memory as shown in figure 1. The video was part of a longer panel discussion with industry experts at ... » read more

Designing 2.5D Systems


As more designs hit the reticle limit, or suffer from decreasing yield, migrating to 2.5D designs may provide a path forward. But this kind of advanced packaging also comes with some additional challenges. How you adapt and change your design team may be determined by where your focus has been in the past, or what you are trying to achieve. There are business, organizational, and technical c... » read more
