Reliability Monitoring Of GUC 7nm High-Bandwidth Memory (HBM) Subsystem


This white paper presents the use of proteanTecs’ Proteus for HBM subsystem reliability based on deep data analytics and enhanced visibility, overcoming the limitations of advanced heterogeneous packaging. It will describe the operation concept and provide results from a GUC 7nm HBM Controller ASIC. A typical CoWoS chip has hundreds of thousands of micro-bumps (u-bumps). 3-8 u-bumps are us... » read more

Week In Review: Manufacturing, Test


Chipmakers Select foundries are beginning to ramp up their new 5nm processes with 3nm in R&D. There are already signs that the foundries have pushed out their 3nm production schedules. So, expect 7nm and 5nm to become long-running nodes. At 3nm, Samsung and TSMC are going in different directions. Samsung is developing a gate-all-around (GAA) technology called nanosheet FETs. TSMC will e... » read more

Scaling CMOS Image Sensors


After a period of record growth, the CMOS image sensor market is beginning to face some new and unforeseen challenges. CMOS image sensors provide the camera functions in smartphones and other products, but now they are facing scaling and related manufacturing issues in the fab. And like all chip products, image sensors are seeing slower growth amid the coronavirus outbreak. Manufactured a... » read more

Taking A Pulse On The IC Biz


It’s been a difficult period for the semiconductor industry. The coronavirus outbreak has put a damper on what was supposed to be a strong year in the semiconductor industry in 2020. Many are holding out hopes for a rebound in the second half of the year. That’s still a big unknown. The forecasts are gloomy. For example, VLSI Research has three different scenarios for the semiconduc... » read more

Metrology Challenges For Gate-All-Around


Metrology is proving to be a major challenge for those foundries working on processes for gate-all-around FETs at 3nm and beyond. Metrology is the art of measuring and characterizing structures in devices. Measuring and characterizing structures in devices has become more difficult and expensive at each new node, and the introduction of new types of transistors is making this even harder. Ev... » read more

Big Changes In Tiny Interconnects


One of the fundamental components of a semiconductor, the interconnect, is undergoing radical changes as chips scale below 7nm. Some of the most pronounced shifts are occurring at the lowest metal layers. As more and smaller transistors are packed onto a die, and as more data is processed and moved both on and off a chip or across a package, the materials used to make those interconnects, th... » read more

Week In Review: Manufacturing, Test


Market research The coronavirus pandemic continues to reduce the outlook for worldwide GDP as well as the electronics and IC markets. For example, IC Insights has lowered its IC forecast from 3% to minus 4% in 2020. The IC market is now expected to hit $345.8 billion in 2020, which is $39.0 billion less than the original forecast, which called for an 8% increase this year. Due to the imp... » read more

Fab tool shipping costs The coronavirus is impacting semiconductor equipment companies. Many have withdrawn their previous forecasts. “It has also led to a rise in shipping costs,” said Krish Sankar, an analyst with Cowen, in a research note. Most semiconductor equipment and components are shipped via air, according to Sankar. The exception is flat-panel display equipment and other sys... » read more

Week In Review: Manufacturing, Test


Chipmakers TrendForce has released its projected foundry rankings in terms of sales for the first quarter. TSMC is still in first place, followed by Samsung, GlobalFoundries and UMC. Samsung has been ramping up chips based on its 7nm logic process using extreme ultraviolet (EUV) lithography. Now, Samsung is ramping up its DRAM devices using EUV and plans to expand its capacity in the arena.... » read more

Week In Review: Design, Low Power


Silicon Labs will acquire Redpine Signals' Wi-Fi and Bluetooth business, development center in Hyderabad, India, and extensive patent portfolio for $308 million in cash. Silicon Labs says the acquisition will expand the company's IoT wireless technology, including smart phone and industrial IoT, and accelerate its roadmap for Wi-Fi 6. The deal is expected to close in the second quarter of 2020.... » read more
