Increase productivity, repeatability and save time.

To support semiconductor manufacturing needs, Thermo Fisher Scientific continues to bring new capabilities to our industry-leading failure analysis, metrology and characterization solutions.

In our Thermo Fisher Scientific PFA Demo Days, we showcased our latest innovations for sample preparation and FinFET logic circuit delayering. The event featured the following live demonstrations:

  • Automatic in-situ lift-out lamella sample preparation with AutoTEM5: Achieving high quality sample preparation repeatability can be challenging. Automating the process can reduce these challenges and increase operator productivity. Featuring the Helios 5 UX, this demonstration will show how simple it is to perform a fully automated in-situ lift-out TEM sample preparation process using AutoTEM5.
  • Dx gas assisted FinFET logic circuit delayering: Semiconductor failure analysis often requires removing layers from the chip to expose regions of interest for defect isolation or nanoprobe testing. Due to different sputter rates of metals and oxides, the basic top to bottom milling box cannot achieve a uniform region. Featuring the Helios 5 PFIB UXe, this demonstration will show how uniform layer-by-layer delayering can be achieved.
  • Large scale cross-section sample preparation and auto rocking polish: Large scale cross-section sample preparation is a common requirement in the backend-of-the-line (BEOL) and packaging stages. Different from traditional Gallium source FIBs, a Plasma FIB can increase the ion beam current to greatly improve large-scale milling efficiency. Featuring the Helios 5 PFIB UXe, this demonstration will show how auto rocking polish can automatically mill a cross-section from different angles and reduce the curtaining effect, caused by a large milling current, to deliver a curtain free cross-section.
