Electrical Analysis Capabilities

Electrical Failure Analysis (EFA) is a critical capability in the semiconductor industry, profoundly influencing various aspects of a business. Here’s how the characteristic features of EFA impact business operations:

  1. Quality Assurance: EFA ensures that semiconductor devices meet the requisite quality standards by identifying and addressing electrical failures.This rigorous quality control is vital for maintaining the trust of customers and upholding the brand’s reputation for reliability.
  2. Product Reliability: By pinpointing the root causes of electrical failures, EFA enhances the reliability of semiconductor devices.This reliability is crucial for applications where device failure can have serious consequences, such as in medical devices, automotive systems, and critical infrastructure. Improved product reliability translates into customer satisfaction and reduced warranty claims, benefiting the business financially.
  3. Innovation and Development: EFA provides invaluable insights into the electrical performance of semiconductor materials and devices.This information is essential for R&D teams to innovate and refine product designs, ensuring that new products not only meet the current market demands but also introduce competitive advantages.
  4. Cost Efficiency: Identifying and rectifying failures at an early stage through EFA can significantly reduce the costs associated with full-scale production errors and market recalls.By optimizing the manufacturing process and enhancing yield rates, businesses can achieve better cost efficiency and profitability.
  5. Time-to-Market: Effective EFA can accelerate the development cycle by quickly identifying issues, allowing for faster iteration and optimization of products. This agility enables businesses to bring new products to market more swiftly, capturing market opportunities and responding to emerging trends.
  6. Compliance and Standards: EFA helps ensure that semiconductor devices comply with industry standards and regulations. This compliance is crucial for accessing and competing in different markets, as well as for avoiding legal and financial penalties associated with non-compliance.
  7. Risk Management: By systematically identifying and addressing potential electrical failures, EFA aids in risk management, preparing businesses to mitigate the impacts of unexpected device failures.This proactive approach can safeguard the company’s operational continuity and reputation.

Comprehensive Testing and Analysis

Comprehensive testing and analysis in Electrical Failure Analysis (EFA) involve the meticulous measurement of various electrical parameters that are crucial for the performance and reliability of semiconductor devices. Below is an outline of these parameters and the role each plays in semiconductor device performance:

  1. Resistivity: This parameter measures how strongly a material opposes the flow of electric current. In semiconductors, low resistivity indicates high conductivity, essential for efficient device operation. High-resistivity materials are used as insulators or in resistive components. Measuring resistivity helps in optimizing material selection and device design to ensure optimal performance and power efficiency.
  2. Carrier Concentration: This parameter indicates the number of charge carriers (electrons and holes) per unit volume in a semiconductor. Carrier concentration affects the conductivity and, consequently, the performance of semiconductor devices.Understanding this parameter helps in tuning the doping level to achieve desired electrical properties, influencing device speed and responsiveness.
  3. Mobility: Electron and hole mobility refer to how quickly charge carriers can move through a semiconductor material under an electric field.High mobility leads to faster charge transport, which is crucial for high-speed or high-frequency semiconductor devices.Measuring mobility is essential for assessing the potential performance of materials in different applications.
  4. Conduction Type: Determining whether a semiconductor is n-type or p-type (depending on whether electrons or holes are the majority carriers) is fundamental to its function in various electronic components.This analysis is crucial for designing and implementing p-n junctions in devices such as diodes and transistors.
  5. Lifetime: The carrier lifetime is the average time that charge carriers remain mobile before recombining.Longer lifetimes are beneficial for devices like photovoltaic cells and light-emitting diodes, where extended carrier mobility enhances efficiency.Measuring carrier lifetime provides insights into material quality and device performance, particularly in optoelectronic applications.
  6. Carrier Concentration Distribution: In many semiconductor devices, having a uniform carrier distribution is critical to ensure consistent performance.Non-uniformities can lead to inefficiencies, localized heating, or failure.Measuring and analyzing the distribution of carrier concentration helps in identifying and correcting such non-uniformities during the fabrication process.


Electrostatic Discharge (ESD) testing services are essential for ensuring the durability and reliability of electronic components and devices in the face of electrostatic discharge events, a common yet potentially devastating occurrence in electronic environments.

ESD testing is critical for verifying that products are robust enough to withstand ESD events, which can damage electronic circuitry, degrade performance, or even lead to complete device failure.

Our ESD testing services encompass a comprehensive suite of tests designed to simulate various ESD scenarios and evaluate the resilience of integrated circuit chips and other electronic products against these incidents.

By rigorously testing products against national, international, and industry-specific ESD testing standards, we ensure that they meet the highest levels of ESD protection required for their intended applications.

The full range of tests provided includes:

  1. Human Body Model (HBM): This simulates the discharge that might occur when a human comes into contact with an electronic device, a common cause of ESD damage. HBM testing assesses the ability of the device to withstand such discharges.
  2. Machine Model (MM): MM testing replicates the discharge that might happen when a device comes into contact with a charged conductive object other than a human, such as a metal tool or machinery.This test is crucial for industrial applications where equipment may inadvertently become charged.
  3. Latch-Up Testing: Latch-up tests are conducted to check for conditions that can cause a semiconductor device to enter a high current state, potentially leading to device failure. This testing is vital for assessing the robustness of the device’s design against internal ESD events and ensuring long-term reliability.
  4. Charged Device Model (CDM): CDM testing evaluates the device’s ability to withstand ESD events when the device itself is charged and then discharged through contact with a grounded object.This scenario is particularly relevant for components that may become charged during manufacturing or handling processes.
  5. Transmission Line Pulse (TLP): TLP testing is used to understand the device’s ESD protection structures and their behavior under ESD conditions.

By providing detailed insights into the device’s transient response, TLP tests help in optimizing ESD protection strategies.
