The Challenge of Custom-Built Tools in the Semiconductor Industry
Semiconductor manufacturing is a highly specialized industry that demands precision, efficiency, and automation. One of the biggest challenges is the reliance on custom-built tools tailored to specific production needs. Unlike off-the-shelf solutions, these tools require extensive effort in design, development, and integration, increasing costs and timelines.
For automation projects, contractors face the significant challenge of delivering a functional tool that meets production requirements. Since every project is uniquely built, a substantial amount of time is spent gathering domain knowledge and refining the design. Despite best efforts, gaps in understanding can lead to discrepancies between intended functionality and real-world production demands. Vendors do not intend to shortchange their customers—they aim to deliver tools they can be proud of—but complexities in semiconductor manufacturing often result in unforeseen challenges.
The Tug of War Between Production and Project Teams
Even with meticulous planning, new tools often end up in storage rather than in active production. Differences in expectations, technical limitations, or integration challenges can create a standoff between production teams and project teams. This is where leveraging in-house domain expertise becomes crucial.
When internal experts who understand the production environment step in, they can bridge the gap between design assumptions and operational reality. They can identify practical issues early, provide real-world insights, and suggest modifications that can make the difference between a struggling system and a fully functional tool.
A Case Study: Recovering a Multimillion-Dollar System
A striking example of this occurred in our facility. A multimillion-dollar automation system faced significant issues with its committed throughput and was on the verge of being either scrapped or commissioned at 40% lower capacity.
After convincing management to allow us to intervene, our in-house team thoroughly analyzed the system and recommended over 15 technical modifications. Two of these changes had an outsized impact, restoring the system’s capacity to 100%.
The key issue was that two sensors were a misfit for the application, causing unnecessary detection failures due to their design. Coming from a semiconductor manufacturing background and understanding sensor behavior and drift, our team was able to technically demonstrate to the vendor that the selection was incorrect. Fortunately, one of the replacement sensors we recommended was available in our company’s catalog, while the second was sourced from our trusted supplier, allowing us to proceed with trials without additional delays.
The impact of these two changes was dramatic, providing a throughput gain that far exceeded expectations. The cost of implementing these changes was less than 0.5% of the total project budget. The improvements were so substantial that we were prepared to fund the upgrade from our own cost center had the vendor declined to take responsibility.
The Power of Empowered Workers and In-House Expertise
This case highlights the importance of empowering workers with domain expertise and involving them in critical automation projects. While vendors bring technical knowledge and engineering capabilities, it is the internal team—those who work with the production environment daily—who can spot potential pitfalls and identify practical solutions that an external contractor might miss.
To maximize success in semiconductor automation projects, companies should:
Engage in-house experts early in the project lifecycle.
Facilitate open collaboration between production teams and vendors.
Allocate resources for continuous technical evaluation and process validation.
Encourage a problem-solving mindset where workers are empowered to propose and test solutions.
By leveraging internal expertise, semiconductor manufacturers can bridge the gap between design and reality, ensuring that investments in automation yield their full potential rather than becoming costly disappointments.
Conclusion
Custom-built automation tools are a necessity in semiconductor manufacturing, but they also introduce challenges in development, integration, and adoption. While vendors strive to deliver the best possible solutions, the complexity of the industry often leads to gaps that only in-house expertise can identify and address. By empowering internal teams to take an active role in automation projects, companies can avoid costly failures, optimize performance, and ensure that their investments translate into real productivity gains.
