Equipment Uptime and FAB speed, part 1

I like to resume with the posts on the topic of FAB cycle time drivers. As mentioned in an earlier post – these are some of the key drivers for factory cycle time: overall factory size (number of equipment available to run a certain step) overall equipment uptime and uptime stability M-ratio rework rate product…… Continue reading Equipment Uptime and FAB speed, part 1

US Semiconductor Ecosystem Outlook

I recently attended the Advanced Semiconductor Manufacturing Conference (ASMC) in Saratoga Springs, NY and listened to a very interesting presentation. Bill Wiseman from McKinsey & Company spoke about the future of the US semiconductor ecosystem and a few fundamental challenges which will have significant impact. Bill is a longterm insider of the semiconductor business and…… Continue reading US Semiconductor Ecosystem Outlook

View into a FAB

Happy Easter everybody ! Today only a very short post – since I’m discussing here normally how semiconductor FABs work in terms of cycle time and output, I thought why not have a quick look inside a FAB ? This post was triggered by a recent YouTube post of an Intel FAB walk, which nicely…… Continue reading View into a FAB

Equipment load port utilization vs. FAB speed

I received and interesting comment to one of the older posts: The topic is indeed very interesting. Most modern semiconductor processing equipment come with 4 load ports. Maine reason for that is to ensure the process chambers can be utilized as much as possible and do not have idle time because of exchange of lots.…… Continue reading Equipment load port utilization vs. FAB speed

The value of 1 day of factory cycle time

Thank you everyone who participated in the last poll. Participation was significantly down beside the fact, that there were plenty of post viewers. My interpretation is that the readers are not too sure about the actual value of 1 day of cycle time. This observation is also in line with my personal experiences from working…… Continue reading The value of 1 day of factory cycle time

Chip shortage and FAB performance, part 3

Today only a very short post ! Very interesting poll results ! Of course the poll left a lot of things open to free interpretation and assumptions, but as expected voters had different opinions. Here is the feedback chart: The same data in the context of the operation curve: If I ignore the outliers at…… Continue reading Chip shortage and FAB performance, part 3

Chip shortage and FAB performance, part 2

Reflecting on the wide spread of acceptable wait times and therefore acceptable FAB cycle times from the poll results, I was wondering: Why do people have these different opinions. I think it has to do with the actual factory conditions, the individual voters have experienced in their professional careers. To have fast cycle times is…… Continue reading Chip shortage and FAB performance, part 2
