Case Study — 3D Wire Bond Inspection and Metrology


The growing amount of electronics within modern vehicles has made the inspection process for wire bonds increasingly challenging, as active devices shrink and bonds are arranged in complex ways. CyberOptics addressed the need for an automated solution to replace labor-intensive and imprecise manual inspection methods for wire bonds and loop heights. After consideration of competitive products, ... » read more

Extracting Intrinsic Mechanical Properties Of Thin Low-Dielectric Constant Materials With iTF Analysis


This white paper focuses on the optimization and use of Bruker’s iTF software package for the extraction of intrinsic (substrate independent) mechanical properties, particularly for thin, low-k materials. These considerations are split into two main parts: Measurement procedure (Section II) and iTF execution (Section III). The former outlines important aspects of acquiring proper experimental... » read more

NIST Modifies & Improves Technique For Detecting Transistor Defects


Abstract "We utilize a frequency-modulated charge pumping methodology to measure quickly and conveniently single “charge per cycle” in highly scaled Si/SiO2 metal–oxide–semiconductor field effect transistors. This is indicative of detection and manipulation of a single interface trap spin species located at the boundary between the SiO2 gate dielectric and Si substrate (almost certainl... » read more

Fundamental Shifts In IC Manufacturing Processes


High chip value and 3D packaging are changing where and how tests are performed, tightening design-for-reliability and accelerating the shift of tools from lab to fab. Heterogeneous integration and more domain-specific designs are causing a string of disruptions for chip manufacturers, up-ending proven fab processes and methodologies, extending the time it takes to manufacture a chip, and ul... » read more

HBM, Nanosheet FETs Drive X-ray Fab Use


Paul Ryan, vice president and general manager of Bruker’s X-ray Business, sat down with Semiconductor Engineering to discuss the movement of x-ray metrology into manufacturing to better control nanosheet film stacks and solder bump quality. SE: Where are you seeing the greatest growth right now, and what are the critical drivers for your technology from the application side? Ryan: One b... » read more

Next-Gen Transistors


Nanosheets, or more generally, gate-all-around FETs, mark the next big shift in transistor structures at the most advanced nodes. David Fried, vice president of computational products at Lam Research, talks with Semiconductor Engineering about the advantages of using these new transistor types, along with myriad challenges at future nodes, particularly in the area of metrology. » read more

Microsphere-assisted, nanospot, non-destructive metrology for semiconductor devices


Abstract "As smaller structures are being increasingly adopted in the semiconductor industry, the performance of memory and logic devices is being continuously improved with innovative 3D integration schemes as well as shrinking and stacking strategies. Owing to the increasing complexity of the design architectures, optical metrology techniques including spectroscopic ellipsometry (SE) and ref... » read more

Unknowns Driving Up The Cost Of Auto IC Reliability


Automotive chipmakers are considering a variety of options to improve the reliability of ICs used for everything from sensors to artificial intelligence. But collectively they could boost the number of process steps, increase the time spent in manufacturing and packaging, and stir up concerns about the amount of data that needs to be collected, shared, and stored. Accounting for advanced pro... » read more
