Well, I have worked 3 days at Qimonda. When I first walked into the FAB, I WAS BLOWN AWAY!!! I did not know what really to expect, but it was amazing. All of the chip making tools like Applied Materials, ASML, DNSE, just to name a few. The robots are all Murata as well as the LEM and OHT. The OHT takes wafers to the tools and the LEM only moves wafers from storage to storage. . IT is about 250,000 sq/ft of space. Very large. It is a 300mm chip wafer that comes out in inches, that is 12 inches; they also have a 200mm FAB that is 8 inches. It is said, that there are planes to build a 450mm FAB at that site, time will tell. I am getting to work on robots ad keep them running. I am learning their systems and procedures. I have to dress fully in a clean room suit. From head to toe. It is a class 10 facility and we can have no hair or skin showing. I have a picture of me in my suit that I am posting on the Blog as well. I am working only days now, but will go to shift work around the end of October. Or that is the plane at the moment. Well, more later.
Both FS 209E and ISO 14644-1 assume log-log relationships between particle size and particle concentration. For that reason, zero particle concentration does not exist. The table locations without entries are non-applicable combinations of particle sizes and cleanliness classes, and should not be read as zero.
