Improving the rate of wafer production information acquisition

Project Introduction: 

In order to form even smaller devices, semiconducting material wafers have had to greatly improve their quality. throughout their producing method, wafer suppliers should still develop high-yield, simplified processes. Advanced method system (APC) has been used for several years to provide a superior product at a competitive value. As a result, correct information assortment is that the key as a result of APC technology depends on scientific discipline applications. There square measure several recurrent processes within the manufacture of wafers, all of that adopted fault detection and organization (FDC) - a system of APC - for the automated detection of kit issues and also the execution of stoppages and alarms. .

System Requirements:

A well-known wafer manufacturer was looking for AN improved answer to its wafer sprucing machine as a result of the initial rate was too slow (one sample/sec), leading to overdoing the grinding method. substitution the machine wasn’t AN possibility because it was still beneath pledge, thus connecting external devices was the sole doable answer to mensuration the AC current of the grinding head motor while not damaging the prevailing lines. It conjointly required to be able to transfer the digital signaling of traditional shut (NC) to manage the grinding head operation.

By mistreatment numerous I/O modules, Advantech provided the simplest non-invasive answer to enhance the rate of wafer production information acquisition likewise as enhancing the performance of its producing machines. 

Advantech’s ADAM-3114-T module and also the serial product of APAX (including APAX-5017, APAX-5070 and APAX-5045) square measure put in within the management cupboard to reinforce the frequency (up to three samples/sec). attributable to weak AC signals, Advantech provided a custom product - ADAM-3114-T, with AN isolated AC current signal conditioner, that amplifies this signals from the detector, and so sends this information to the APAX-5017 that is answerable for receiving the analog signals. 

Meanwhile, the APAX-5070 Modbus/TCP Communication coupling, transmits thegrinding head motor information to the server via the computer network so the supervisor will check the machine’s operative standing. If anything’s wrong the user will close up the machine via the APAX-5045 Digital Input/Output Module that takes charge of the grinding head management via the Digital Output. Advantech conjointly offers alternative choices for the client to upgrade their system. as an example, beneath identical portfolio, users solely ought to add a lot of channels and also the rate are often exaggerated up to twenty samples per second or perhaps a lot of.

Conclusion:

Wafer fabrication is hard and complex and new processes ought to be designed for every stage of development and examination to permit for faster production. Advantech’s vary of prime quality product ensured that not solely square measure the customer’s desires met, however conjointly that the user will turn out a lot of things, scale back scrap and improve period of time. Since this project has been finished for a few year and has shown wonderful results, Advantech is currently the primary selection for any future comes.
