ADAM configuration I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. Continue the topic on ADAM controller, as you can see from the photo below, it can be connected to many different function sensors. Just need to take note the exact channel will do. After physically connected to the ADAM, you need to go ADAM @net software to do the configuration of channels. For different small card, also of different function, 5017 can…

Small ADAM for communication I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. Small ADAM is used when you know there are limited channels that you going to have for a tool. With only 8 channels configurable, you'd better make sure you do not need to add more channels in near future to prevent channels not enough. The only good thing about Small ADAM only is its size is handy , so simply a box able to fit it and work fine.…
Chillers for semicon I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. There are several types of chillers in use in our plant. The most popular is this blue color type, called Neslab Chiller It has a upgraded version, also called Neslab but in white color, so we call it Neslab White. Just to differentiate the old and newer model: Both Neslabs models is already obsolete, where the maker of the chillers not supporting the…
Metal peeling I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. Today I wanna talk about process related issue in our line. We called it in layman term peeling. Meaning the metal which supposed to deposit onto the product is not sticked to the wafer but peeling off when it comes out from machine. First let you to see mild cases: As you can see sides have got minor peeling. This is more serious. top side is peeling off very…
The BJ story in semicon industry I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. In our line of semicon, we refer BJ to belljar. The function of belljar is to suck. Suck away the oxide layer on the product (wafer) before the next step metal deposition. But you cannot let the BJ to suck too much. Working too hard (Used too frequent) then it could explode. And you will get very "excited" to see this scene. All BJ broken…
Gold deposition peeling I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. Continued yesterday topic - the gold deposition peeling off. The seasoning wafers that get peeled off need to gathered and do analysis soonest possible. The peeling can fly off anywhere, and the most sticking could be those with contact with chamber, eg the wafer holders. All the wafer holders need to change with new assembled. Another big problem…
Gold target lockout I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. As our process run with precious metal, there are many security layers implemented. Not only did we need to step by step withdraw the target, we also need prevent from physical lock to the machine. There are many different locks design we design and trial. First we made a full metal box to cover the whole target. But over years we found that design is…
Heater flatness I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. In the chamber, heater is the most critical part, not only does hot surface makes the deposition at faster rate, but evenness of the heater to make sure the deposition of metal is equallly onto the whole wafers. This is how it looks like , a wafer sitting on a heater. When we dismantled out the heater, rough gauge is by using a ruler, though not a good one.…
Aluminium Copper peeling I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. The process involves the metal deposition onto the wafers, it's just matter of what target material to be deposited subject to the process need. This I am going to show is Aluminium Copper (AlCu). As you can see, the surface of the clamp ring is popping up like going to peeled out. While the bottom side already have portion that already come out.…
Heater installation and inspection I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. In our production line, heater plays a vital role, because only with hot temperature, the process able to take place and do the metal deposition. So to monitor the heater performance and lifespan become important. This is how it looks like for a heater. Today we get a heater from the leader, need to install into a chamber for replacement.…
Target debonded I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. Last week , a tool in our production line ran into problem , failing some parameters constantly. So we decided to open the chamber and perform the inspection. Found out the target (tantalum) had been debonded. From surface it looks like uneven surface. Looks like patch by patch over the target Back of the target hardly see any abnormaliy. Possible root cause…
