Improving Wafer Processing with Automated Equipment

Fully and semi-automated wafer processing equipment can help improve wafer output quality by providing consistent chemical processing dosages and timing. However process settings must first be determined manually, then in semi-automated mode where the settings can easily be adjusted or fine-tuned.

This especially applies to new process development where the exact parameters are yet to be determined. Wafer fabrication facilities may try out the initial settings first in manual mode and make some appropriate adjustments. Then they may automate some of the processes using semi-automated stations for parts of the process that are finalized while making additional manual adjustments for optimize results. The final processing parameters can then be implemented in a fully automated station.

After the initial run, the problem areas can be identified, and variables such as chemical dosages and timing can be revised and adjusted. Skilled and experienced operators can do the fabrication steps and make changes easily on the manual station. In manual mode operators has complete control of the process. This control is important for determining the initial settings of a new process.

When the changes have been finally made on the major parts of the new process, there may still have some necessary minor adjustments necessary to achieve targets such as faster processing, better quality output or reduced usage of chemicals. For this reason, the semi-automated stations can be used to save time.

Once the parameters and variables for the desired yield and performance have been determined, a tailor-made software and automation package can be assembled. These packages are implemented in fully automated wafer processing equipment which can reproduce the custom settings of the manual and semi-automated process steps and use them to produce the desired results consistently.

Modutek can work closely with a customer to determine the best way to optimize a new process.

Advancements in Wafer Fabrication Equipment Improve Semiconductor Manufacturing

The improvements in wafer fabrication equipment have kept up with the growing industry demands in high precision wafer fabrication. Precision is required to ensure adequate output quality and a low component rejection rate.

Automation has become the norm since it requires minimal manual handling. More so, it is needed to meet stringent requirements which allow fabrication shops to boost their productivity, minimize errors, reduce waste, and prevent additional costs.

Modutek offers fully automated wafer fabrication equipment which provides fully automated control of the wafer fabrication process. It has integrated software such as Modutek’s SolidWorks Flow Simulation and SolidWorks Simulation Professional which allow operators to calculate process variables and track chemical usage. Once the process is programmed, the advanced robotics will execute the process steps without intervention or monitoring from the human user. This results in a consistent process environment, increased throughput and increased output quality.

Both the software and the robotics have significantly improved process control, reliability and efficiency. Since a lot of semiconductor suppliers have their own requirements for different kinds of wafer manufacturing, Modutek designs the equipment, assembly and testing, and even the software, to match these specific customer requirements.

The last etch process involves etching the silicon wafer to remove the silicon oxide layer and then drying the cleaned wafer in a drying chamber. At this stage, any contamination can negatively affect later processes and will result to semiconductor components of inferior or defective quality. Modutek’s newest product introduces the combination of the last etch (HF) and IPA drying chamber to prevent handling the silicon wafer and thus reduce its chances of contamination.

Determining Which Wafer Processing Station Will Meet Your Requirements

Wet benches stations are available in various configurations which are designed for different applications. Because of this, clients may have a difficult time deciding which equipment to choose that will best meet their requirements. One way to reduce the uncertainty and to make the selection more defined is to focus on three areas where your requirements must be met.

A wafer processing station needs to address the following items:

1) Compliance with standards
Wet bench stations should comply with the following industry standards to ensure safe operation and resistance to combustion:

  • NFPA – National Fire Protection
  • NFPA 79 – Safety of Industrial Machinery
  • NEC – National Electrical Code
  • UL 508a – Standard for Industrial Control Panels

If wet bench stations have to be installed outside the US, Modutek is also able to comply with a foreign country’s own local and national safety standards. In addition, Modutek can supply third-party certification for compliance.

2) Applications
Modutek can supply the right systems and advise on the benefits and advantages of certain products from their complete line of wet bench equipment, depending on the process or application required.

3) Automation
Modutek offers manual, semi-automated and fully automated wet bench stations. You should know your needs first before deciding whether you want a manual or automated model:

  • Manual – ideal for low volume custom or prototype device processes. It has the most competitive pricing among the three models.
  • Semi-automated – has some automated features and provides uniform processing without the higher priced associated with fully-automated models
  • Fully automated – ideal for hands-off operation and higher volume with standard processes. It improves higher throughput and minimizes human errors.

Modutek’s wafer processing stations are developed and manufactured with the same high-quality materials but it can also supply the appropriate degree of automation that will meet the customer’s needs and specifications.

Custom Fabrication Services for Unique Wafer Processing Requirements

Research labs and semiconductor manufacturing facilities often have special requirements for certain projects or prototypes that may need custom equipment to support their manufacturing procedures.

Semiconductor manufacturing facilities may need customized tanks, carriers or chemical stations to manufacture a particular product or may need to change existing equipment based on external changes or new requirements.

When new products are developed, single items are manufactured, or prototypes are done for testing, existing wafer processing equipment being used may not be suitable for the job. There are many factors: changing suppliers and/or environment and safety regulations imposing additional requirements or changing existing ones. In such cases, retrofitting the equipment, adding new components or changing parts or any other customization may be the best and most cost-effective solution to meet the current requirements.

On the other hand – other semiconductor manufacturers want to customize their existing equipment to let themselves adapt their production lines to current requirements, to speed up production and to increase throughput.

Fortunately, Modutek can provide expertise and experience to manufacturers when customized solutions are needed to support their unique wafer processing equipment requirements.
