X-Ray Inspection for Semiconductor Package Failure Analysis

Many important semiconductor package defects are completely hidden from optical inspection. A solder ball can contain a void. A bond wire can be broken inside an encapsulated package. A die-attach layer may contain large areas of voiding. A package substrate can contain an open trace, and an advanced package may have ...

China Imposes Export Restrictions on Key Minerals to the United States

The Chinese Ministry of Commerce today announced immediate export restrictions on gallium, germanium, antimony, and super-hard materials to the United States. This action cites national security concerns and represents a significant escalation of trade tensions between the two countries. The restrictions follow recent U.S. actions to curb exports of semiconductor-related ...

Choosing, Integrating and Managing Chiplets

Chiplets are a relatively recent advancement in semiconductor technology that involves breaking down a traditional monolithic integrated circuit (IC) into smaller, individual semiconductor components or "chiplets." These chiplets can be designed and manufactured independently, and then they are integrated onto a common substrate or package to create a more complex ...

IC Failure Analysis Techniques: A Complete Guide

When an integrated circuit fails, identifying the damaged component is only part of the challenge. Engineers must determine where the failure occurred, what physical or electrical mechanism caused it, and ultimately why it happened. This requires a combination of specialized IC failure analysis techniques. Some techniques detect electrical abnormalities without physically altering ...
