Nanoprobing is a technique used largely in the semiconductor industry for obtaining device electrical characteristics using tiny tungsten wires. Individual device characterisation is useful to engineers and integrated circuit designers during early product development and debugging.
It is frequently used in device failure analysis laboratories to help with yield improvement, quality and reliability concerns, and customer refunds.
Nanoprobing systems are incorporated into vacuum-based scanning electron microscopes (SEMs) or atomic force microscopes (AFMs). Atomic Force nanoProbers (AFP) are nanoprobing systems that rely on AFM technology.
AFM-based nanoprobes allow for the scanning of up to eight probe tips to provide high resolution AFM topography pictures, as well as Conductive AFM, Scanning Capacitance, and Electrostatic Force Microscopy images.
Conductive AFM has pico-amp resolution for identifying and localizing electrical failures such as shorts, openings, resistive contacts, and leakage channels, allowing for precise probe positioning for current-voltage measurements.
AFM-based nanoprobes allow for nanometer-scale device defect localization and precise transistor device characterization while avoiding the physical damage and electrical bias caused by high intensity electron beam exposure.
The ultra-high resolution of the microscopes that contain the nanoprobing system allow the operator to maneuver the probe tips with precise movement, allowing the user to see precisely where the tips will fall, in real time, for SEM-based nanoprobes.
Nano Probing is a solution incorporated or to be embedded in a SEM that is based on cutting-edge nano probes, nano manipulation, motion control solutions, flexible electrical characterization tools, and other unique designs/tools that enable the best electrical probing quality.
Nanoprobes are sophisticated fault isolation devices that can precisely find and characterize electrical flaws on the nanoscale scale that affect device performance and reliability. Individual transistors and connection architectures are probed by nanoprobers.
The Global Nano-Probing System Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The SMARPROBE LX nanoprober was designed to take nanometer-resolved closed-loop probing to the next level of efficiency and stability. It permits up to eight probes to be positioned to analyze or modify samples fastened to its sample stage.
The technology may be integrated into an electron microscope for failure analysis or an optical microscope for atmospheric probing of big samples.
The Hitachi NP6800 is a specialized probing system based on SEM that is designed to address the analytical demands of design node semiconductor devices and beyond.
The precision piezoelectric-driven actuator has probe motions on the X, Y, and Z axes, allowing the probes to be accurately manipulated for measuring the electrical properties of a single MOS transistor.
Through their intuitive probe operation design, they were able to construct an easy-to-use probing system (similar to an optical probing system) while preserving the same simplicity of operation even in a vacuum environment.
This SEM-based probing system is used to analyze faults and failures that may occur during the fabrication of any nanoscale semiconductor device.
The NP6800 Nano-Prober is equipped with an optimized cold field-emission electron source, an eight-prober system, a temperature-controlled stage, an AC measurement system (optional) for gate-resistance detection, an EBAC system for short and open failure localization, and probe and specimen exchange units for maximum throughput.
The NP6800 Nano-Prober was designed as a specialized nano-probing system for both high-throughput and high-stability measurements of nano-scale semiconductor devices. The system can assess electrical properties, EBAC, EBIC, pulse IV, and temperature needs of nanoscale devices.
The Hitachi NE4000 nanoEBAC is an electron beam probing system designed for electrical characterization, EBAC analysis, and imaging of microelectronic device interconnects, materials, and components.
The Electron Beam Absorbed Current (EBAC) technology identifies open circuits, excessive resistance, and shorts along interconnects without using direct probing techniques on lower level layers.
The EBAC technology absorbs electron beam current by transmitting the electron beam via the dielectric layers down to the lower level metallization layer.
The FESEM’s electron beam accelerating voltage governs the probing depth or amount of penetration into the dielectric layers. To complete the circuit and allow electrons to flow, a single probe is put on the exposed top layer metallization.
