Dry, Particle-Free Wafer Downsizing in the Cleanroom

Learn how you can downsize wafers and prepare samples in the cleanroom—without compromising the cleanliness of the cleanroom or wafers. Contact lg@latticegear.com for a copy of the paper.

First you may ask “Why implement a cleaving process in the cleanroom?”:

Here is what the Operations Director of a National Nanofabrication Facility had to say,

“Here at our nanofabrication facility, we found that after installing the micro-indent [LatticeAx 420] in our cleanroom, users are no longer cleaving samples in the lithography area. Additionally, the “cleaner” cleaving process of the micro-indent creates very few shards and particles that are easily vacuumed. Users are motivated by the capabilities of the LatticeAx and rewarded with a cleaner process. It’s a win-win scenario”

LatticeGear presents a process and data showing how the LatticeAx 420 scribeless cleaving system was used to cleanly cleave wafers. To obtain statistics, 60 samples were cleaved out of 10 whole, 4” silicon wafers. The results showed no increase in particle count.

Particle count comparison for 0.3 micron size, before and after wafer cleaving, points 1-3.

LatticeGear wishes to thank the University of Sydney (Ethel Cabrera Ilagan) and Penn State University for their assistance with this study.

Cleaving with LatticeGear Cleanbreak Pliers

When cleaving pliers are used correctly they can produce long straight cleaves on crystalline substrates or wafers. When the wrong jaws are installed or the user tries to cleave with the sample in the wrong orientation disaster can occur!

LatticeGear has produced a HOW TO USE CLEAVING PLIERS video showing how to;

  • decide which type of jaws to install (there are two types)
  • install the cleaving jaws,
  • cleave a sample (glass and silicon) and
  • remove and replace jaws when they are worn out

For  small samples (<15 mm) use LatticeGear’s small sample cleaving pliers

LatticeGear and V-TEK Share Cleaving and Scribing Insights with Taiwan Universities

Last week, LatticeGear with the great support of its local agent, V-TEK Co., LtD., delivered the seminar about ‘The power of the weak point: how to secure clean imaging and true analysis (in cleanroom too) at leading academic institutes across Taiwan (CGU, NTUST, NCKU, NCHU, NCTU) aiming to educate those who need to use cleaving technology (downsizing, cross-sections) to prepare samples for characterization.  This type of lecture is not part of any curriculum, yet fundamental for research and development.

It was highly appreciated by those professors who are responsible for nanofabrication facilities to teach users how to properly cleave in the cleanroom with no contamination, as well as for researchers with limited sample material and must secure sample prep outcome (without the luck factor). Accurate characterization requires clean, sample preparation that does not alter the surface / sub-surface of the starting material.  While we all invest much time and funds into our microscopes, we hardly talk about sample prep, YET as the microscopes advance, correct sample prep becomes critical.

Please contact LatticeGear at lg@latticegear.com if you would like to schedule a seminar at your industrial or academic laboratory.

Niels Bohr Institute Researchers Successfully Cleave Delicate Nanostructures

Scientists in the Quantum Photonics Group at the Niels Bohr Institute of the University of Copenhagen who are developing new technologies for photonic and quantum-information applications used the LatticeAx to alleviate one of their biggest sample preparation challenges: precise cleaves on small samples without damaging delicate fabricated nanostructures. Scientists are engaged in leading edge research to investigate the quantum interactions between light and nanophotonic semiconductor materials. They needed a way to cleave small sample without damaging the delicate devices. Cleaving using hand held scribers and cleaving tools did not produce the quality needed but the LatticeAx 420 cleaving system was able to do the job.

LatticeAx Cleaving Tool In the Cleanroom at PennState Materials Research Institute

Did you know that you can use the LatticeAx indent and cleaving tool at the PennState Materials Research Institute? The LatticeAx 420 is located in the Nanofabrication Laboratory cleanroom. It has improved the success rates for preparing cleaved samples in comparison to manual techniques using handheld tools. The LatticeAx is simple to use and can cleanly downsize samples or prepare cross sections prior to SEM or other analysis. If you need to prepare samples free of particles in a cleanroom environment, Contact the nanofabrication facility at nanofab@psu.edu.

High quality downsizing by LatticeAx cleaving improves planar polishing accuracy and success rates

At ISTFA 2016 in Fort Worth, Texas LatticeGear presented customer results describing how the LatticeAx indenting and cleaving system was used for precise downsizing of a <100 micron thin die that was removed from its package prior to delayering. Delayering a thin, fragile die (layer by layer, edge to edge) is a manual process, an art. Typical downsizing methods such as sawing or manual cleaving can be difficult to control resulting in fractured die and lost targets. A LatticeAx tool owner developed an innovative downsizing solution using the micro line “indent to cleave” process. It is a hands free, 2 minute process. The application is most appealing when the target area is known and the sample thin <100 microns. The following images show the process. Contact lg@latticegear.com for more information on this application.

LatticeGear demonstrated the new LatticeAx 225 at ISTFA 2016

LatticeGear exhibited at ISTFA 2016 in Fort Worth, Texas, November 8-9. A full suite of cleaving and scribing tools was demonstrated. The tools included the new LatticeAx 225 high accuracy indenting and cleaving system, small sample pliers and the FlipScribe backside scriber. LatticeGear also presented a presentation called “Using Micro line indentation to downsize thin and out-of-package-die”. It was a good time to learn about best practices for sample preparation of electronic devices and to catch up with colleagues in the industry.
