Ferroelectric Memories Answer Call For Non-Volatile Alternatives


As system designers seek to manipulate larger data sets while reducing power consumption, ferroelectric memory may be part of the solution. It offers an intermediate step between the speed of DRAM and the stability of flash memory. Changing the polarization of ferroelectric domains is extremely fast, and the polarization remains stable without power for years, if not decades. FeFETs, one of ... » read more

Reverse Laser Assisted Bonding (R-LAB) Technology For Chiplet Module Bonding On Substrate


By SeokHo Na, MinHo Gim, GaHyeon Kim, DongSu Ryu, DongJoo Park, and JinYoung Kim In the recent semiconductor market, there are many applications including smartphone, tablets, central processing units (CPUs), artificial intelligence (AI), data cloud and more that are expecting and experiencing rapid growth. As most of these applications require high performance, single-die Flip Chip packages... » read more

Why Curvy Design Now? Manufacturing Is Possible And Scaling Needs It


Have you ever seen roots or tree branches take a 90-degree turn? Have you ever seen a river that takes a 90-degree turn? Nature doesn’t do 90-degree turns, or for that matter any sharp angle turns – not even 135 degrees. Yet the entire chip-design infrastructure is based on the Manhattan assumption of 90-degree turns. While it would take time to change, is there any doubt that a curvilinea... » read more

5 Reasons Why Defect Reduction Is Critical In Semiconductor Material Success


Semiconductors may be small, but the impacts they have are significant. Semiconductors used in life-dependent applications, such as pacemakers, defibrillators, life support systems, automotive safety systems, or in aviation need to be fail-proof. A device smaller than a centimeter with features just a few nanometers has no margin of error. This blog shares why it’s important to detect materia... » read more

New Plasma Power Technologies For Next-Gen Semiconductor Manufacturing


As chip designs push the limits of speed, size and complexity, the semiconductor industry has set its sights on angstrom-scale device features. High-speed, precise and repeatable plasma power delivery with sophisticated controls is fundamental to process and device improvements. These factors support inflection points in technologies from chip-scale packaging through advanced front-end technolo... » read more

Reliability Performance Of S-Connect Module (Bridge Technology) For Heterogeneous Integration Packaging


Bridge technology is a promising heterogeneous integration (HI) solution for application-specific integrated circuits (ASICs) and high bandwidth memory (HBM). The bridge dies provide localized communications among the multiple system on chips (SoCs) in a single package. In Amkor's bridge technology, S-Connect provides die-to-die connections with fine pitch [1]. Prototype S-Connect technology wa... » read more

Functionalized Carbon Nanotubes Enabled Flexible And Scalable CO2 Sensors


This work, we have demonstrated a low-cost and effective chemiresistive CO2 sensor based on a composite of functionalized carbon nanotubes (f-CNTs) with polyethyleneimine (PEI). The resulting sensor shows excellent selectivity and sensitivity, which can respond to the CO2 concentration in a wide range of 300 - 5000 ppm. The effects of ink dilution and humidity from the environment on the sen... » read more

Challenges Of Testing Advanced Packages


The number of things that can wrong in assembly and test increases as more chips are added into a package. Testing is the usual guarantor of a reliable device, but in an advanced package there are all sorts of new issues — more contacts, different handling requirements, the necessary thermal conditions for test, and variation within the package. George Harris, vice president of global test se... » read more

Chip Industry Week In Review


By Gregory Haley, Jesse Allen, and Liz Allan TSMC told equipment vendors to delay deliveries of the most advanced tools due to uncertain demand, according to Reuters. The news drove down stock prices of all the major equipment providers. On the other hand, TSMC said advanced packaging shortages will constrain AI chip shipments for the next 18 months, according to NikkeiAsia. The United St... » read more

Chip Industry Week In Review


By Liz Allan, Jesse Allen, and Karen Heyman Global semiconductor equipment billings dipped 2% year-over-year to US$25.8 billion in Q2, and slipped 4% compared with Q1, according to SEMI. Similarly, the top 10 semiconductor foundries reported a 1.1% quarterly-over-quarter revenue decline in Q2. A rebound is anticipated in Q3, according to TrendForce. Synopsys extended its AI-driven EDA ... » read more
