Technician's life Hello world, I am new to this space. and am introduced by @sitisan to write and share. I am a technician in semiconductor sector in Singapore, as I explore , not many articles about this area here in this space. So I think I would like to share more in this area. Maybe not many people know that, Singapore also one of the countries with strong semicon fundamental, this ensure the country to continue its edges in technology, and not rely only on service…

Semicon - magnet and target Today I wanna continue talk about the semicon stuff in Singapore. Picture below is a magnet, a super strong magnet plotted polarity in order, so the magnetic field is very strong, dont get near your phone with it , or else will stick to it and hard to dispatch. This is called the RMA type magnet. Two versions of it , one is silver color and newer design is black color. The use of magnet is attracting the ionized metal , to be bombarded into the…
Wafer thickness measurement tool In Semicon especially in Singapore wafer fab which demand a high quality output, Every product will need to go tru some sampling check. Meaning to random check whether process is under control eg if we wants the metal deposition to be certain thickness, the machine cannot deposit more or less to certain percentage, eg plus minus 5%. Thicker or thinner of the metal will affect the product performance. So we use the RS machine to sampling check…
Transfer Robot Arm I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. To move the product from the cassette into machine and run processing - deposit few layers of different metals onto the product wafers. The machine need a robot arm. This is how the robot arm looks like: At first glance , it really looks like a Lego toy. But in actual fact, our this machine since it's pretty old technology (history up to 30+ years). We…
Belljar & issues I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. A belljar is made of quartz, and its function is to etch away the oxide layer of the wafers, before proceed to next step- metal deposition. But one common problem with belljar is due to man made mistake- that is running with wrong wafers and get etched away into Belljar, so the belljar is contaminated with metal coating. Using multimeter ad can see the…
Wafer Holder Assembly I work as technician in a Singapore semiconductor factory. Here I share my working life as technician. The product -wafers need to transfer from the cassette to the machine , and 1 by 1 mounted onto wafer holder and transfer into chambers to do the deposition. This is the wafer holder housing, as you can see 2 ceramic pins at the side to hold the assembly to machine seal ring This is the clamp ring, wafer sit on this piece. The full set of PM kitting…
