Very helpful video, thanks for uploading!

[@Stevenebe462]

Thanks for the amazing video. I am wondering if ASML Orion system can use other company’s alignment mark design? E.g can 2000i use Intel’s own alignment mark? Thanks.

[@SemiSlides]

Thank you for the great feedback and for watching the video! Regarding your question about the ASML Orion system and the use of Intel's alignment marks, that's a great query. However, our channel doesn't disclose any information that could infringe on a company's confidential details or trade secrets. In general, ASML systems are designed to be quite versatile, but specific implementations involving proprietary designs like Intel's alignment marks would fall into the category of confidential information. Thanks for understanding, and keep exploring the fascinating world of semiconductors! 😊

@@SemiSlides also curious what is the difference between alignment mark and overlay mark? in terms of functionality

[@SemiSlides]

Hey there, Silicon Pioneer! Great question! Let's dive into the differences between alignment marks and overlay marks from a functionality perspective, especially in the context of ASML Twinscan systems. Alignment Marks: These are used to align the reticle (the photomask) with the wafer. Given that photolithography equipment is expensive, maintaining continuous operation on the exposure side is the top priority. Therefore, the alignment measurement on the measure side must be completed in less time than it takes for the exposure side to process a single wafer. This means the system can't align every single field on the wafer individually. Instead, it focuses on aligning the entire wafer with the entire reticle to keep things running smoothly and efficiently. Overlay Marks: These come into play after the exposure and, unlike alignment marks, the process doesn't affect the expensive ASML system's productivity. As a result, a separate overlay measurement system can be used to thoroughly and massively measure the overlay for each individual exposure field. This helps identify any misalignment across all the exposure fields and provides detailed feedback to ensure better alignment for future exposures. And hey, apologies for the delay in getting back to you. Sometimes, the notification system likes to take its sweet time. Thanks for your patience! Keep those awesome questions coming! Cheers, Semi Sherpa 🌟
