Department Databases At Intel

At Intel there are many databases that we use to do business. Most of the databases that we use are very complicated and require a lot of training and proficiency to surmount the program. In the clean room at Intel Corporation, we use a specific type of database to keep track of each and every microchip that we make. Since we make millions and millions of microchips and it takes many different machines, processes, and people to make these chips, the database has to be able to handle all of this information. This database that we use is called Work stream.

Work stream is such a complicated interactive database that is much different than any other that I've seen before. It is a UNIX based system that looks very old. It might look old, but the function is outstanding. In fact, it acts like it is its own operating system because it is so big and has many different commands to get you to certain pages. The input comes from two different places. One place is from the operators or technicians that make the microchips, and the other is from the tool sets (or equipment) themselves. These commands that are inputted take you to a particular page or query in the database where you can add different data about the microchips that we process, or even the tool sets that the lots of microchips process on. Every lot (or group of microchips or wafers) and every tool set has its own identification number that is inputted into the database for tracking. Everything that is done to any microchip and tool is documented. For instance, when we do preventive maintenance on the tool, we document everything that we do to it in Work stream to verify what we have done. This way, if something goes wrong, we can
