Hunting For Macro Defects


Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the wafer level, a macro-defect can affect more than one die, and in some cases large regions of a wafer. Finding macro defects can indicate a significant issue with a process module, a particular fi... » read more

Chip Industry Week In Review


Check out our new Inside Chips podcast. President Trump’s ‘Liberation Day’ tariffs were announced this week. The executive order stated that semiconductors and copper imports are not directly subject to the reciprocal tariff, although the exemption may be short-lived. Semiconductor equipment and tools were not mentioned, leaving the industry searching for clarification. Regardless, hig... » read more

Need For KGD Drives Singulated Die Screening


The move to multi-die packaging is driving chipmakers to develop more cost-effective ways to ensure only known-good die are integrated into packages, because the price of failure is significantly higher than with a single die. Better methods for inspecting and testing these devices are already starting to roll out. High-throughput infrared inspection is capable of catching more sub-surface d... » read more

Failure To Launch


Failure analysis (FA) is an essential step for achieving sufficient yield in semiconductor manufacturing, but it’s struggling to keep pace with smaller dimensions, advanced packaging, and new power delivery architectures. All of these developments make defects harder to find and more expensive to fix, which impacts the reliability of chips and systems. Traditional failure analysis techniqu... » read more

Chip Industry Week In Review


The Malaysian government signed a deal with Arm to kickstart a chip design ecosystem. Until now, Malaysia has focused on packaging and test. Adding chip design represents a major change in focus. The country will pay SoftBank $250 million over 10 years for Arm’s chip design IP and train 10,000 engineers. Global chip sales reached $56 billion in January, up nearly 18% from the same period i... » read more
