When your wafer is complete, use semiconductor inspection software to test the data and the alignment. The software reads the information on the wafer and checks the positions and the notch location. If the reading is successful, the inspection software sends the scribed serial number on the wafer back to the host which validates the wafer.

If the semiconductor inspection report indicates an error, the reading software, by design, readjusts the filters to re-read the scribe. The wafer returns to its final position once the software relays a message announcing the resolution of the problem.

1. Obtain training and insight in the semiconductor inspection process by consulting with a vendor who knows your unique requirements.

2. Use semiconductor inspection software that checks for defects as well as particles on wafers.

3. Address the semiconductor inspection solution suggested by your software.

The best contacts and resources to help you get it done

Consult with semiconductor inspection software vendors to find the best software for your needs

Learn about various types of semiconductor inspection software options including semiconductor inspection software applications by talking with someone who knows the ins and outs of the business. A vendor often has knowledge of the most current options available and makes suggestions that you might not have known about.

I recommend: Aegis Solutions, Inc. is a member of the National Instruments’ Alliance. They offer on-site training for its software systems and use stand-alone applications or applications that have the ability to integrate with equipment a customer already owns. Nikon Instruments Inc. offers an advanced, cost-effective wafer inspection and review software called DART. DART Software allows users to re-collect, assess and categorize defects based upon an integrated graphical map.

Understand your software through semiconductor quality control consulting

When using software for semiconductor inspection, there are many facets to the program you might miss. Talking with a consultant helps you get a better understanding on the semiconductor inspection report and other features of the software.

I recommend: Intota is a business-to-business service of Guideline, working with companies who meet the ISO 9000 International Standards. Their knowledgeable consultants are highly knowledgeable on quality control inspection points and work with clients to meet specified requirements. SAFC Hitech has a team of analytical experts dedicated to providing personalized service and support to customers to ensure the best use of their updated technologies.

Use a semiconductor inspection solution to complete intricate analysis of semiconductor components

Use a semiconductor test software solution to pinpoint errors in patterns or on the wafer itself from fine particles. Software solutions find the errors and auto correct to save you time and money.

I recommend: Lasertec Corporation offers a patterned, wafer inspection system with their WASAVI Series SK300. It’s compatible with wafers that have advanced, fine patterns like 45 nm and more. If you are more interested in a consulting service for your inspection software solutions, consider Accu-ray Inspection Services, Inc. which uses Automatic and Image Intensifier x-rays to detect and resolve problems.
