SEMISHARE: Pioneering Prober Machine Innovation for Advanced Semiconductor Testing

In the rapidly evolving world of semiconductor technology, the importance of reliable and precise testing equipment cannot be overstated. At the forefront of this critical industry stands the prober machine - an indispensable tool in ensuring the quality and functionality of semiconductor devices before they reach the market. As a leading wafer probe company with over 14 years of experience, SEMISHARE has established itself as one of the preeminent wafer prober manufacturers globally, consistently delivering cutting-edge prober machines that meet the exacting standards of the semiconductor industry.

What is a Prober Machine?

A prober machine, also known as a wafer prober or probe station, is a sophisticated piece of equipment used in the semiconductor industry to test integrated circuits at the wafer level before packaging. This essential device allows manufacturers to identify and isolate defective chips early in the production process, saving time and resources. SEMISHARE's prober machines are designed to perform a wide range of tests, including parametric testing, functional testing, and reliability testing, ensuring that only high-quality chips make it to the final product.

How Does a Wafer Prober Work?

The operation of a wafer prober is a testament to the precision engineering that goes into its design. At its core, a wafer prober works by making precise electrical connections between the device under test (DUT) on the wafer and the testing equipment. This is achieved through a series of intricate steps:

1. Wafer Loading: The silicon wafer is carefully placed on the chuck, a specialized platform within the prober machine.

2. Alignment: The prober aligns the wafer using optical recognition systems to ensure accurate positioning.

3. Probe Card Contact: A probe card, containing numerous tiny probe needles, is lowered onto the wafer, making contact with specific test points on the chips.

4. Testing: Electrical signals are sent through the probes to test various parameters of the chips.

5. Data Collection: The prober machine collects and analyzes the test data, identifying functional and non-functional chips.

6. Wafer Mapping: The results are used to create a wafer map, showing the location of good and bad dies on the wafer.

SEMISHARE's prober machines excel in each of these steps, offering unparalleled precision and reliability in wafer testing.

What is a Probe in Semiconductor Testing?

In the context of semiconductor testing, a probe refers to a conductive needle-like structure used to make electrical contact with specific points on a semiconductor device. These probes are crucial components of the prober machine, serving as the physical interface between the testing equipment and the device under test. SEMISHARE's prober machines utilize state-of-the-art probe technology, ensuring accurate and consistent electrical connections for reliable test results.

How are Silicon Wafers Tested?

Silicon wafer testing is a complex process that involves multiple stages and sophisticated equipment. SEMISHARE's prober machines play a pivotal role in this process, offering comprehensive solutions for wafer-level testing. The testing process typically includes:

1. Visual Inspection: Automated optical inspection systems detect surface defects.

2. Electrical Testing: This is where SEMISHARE's prober machines shine, performing a variety of electrical tests to verify the functionality of each die on the wafer.

3. Parametric Testing: Measuring electrical characteristics to ensure they meet specified parameters.

4. Functional Testing: Verifying that each circuit on the wafer performs its intended function correctly.

5. Reliability Testing: Subjecting the wafer to stress conditions to predict long-term performance.

SEMISHARE's advanced prober machines are designed to handle all these testing requirements with exceptional accuracy and efficiency.
