The modular system of ACS300 Gen3 is specifically designed for demanding high-volume production environments. It provides sophisticated coating, developing and baking functionalities that can be easily adapted to various processes. Maximum process control effectively supports the wide field of use. This, together with the smallest footprint on the market for a system with eight spinner modules, all qualities positively affecting cost-of-ownership, make the tool indispensable for any challenging advanced packaging application such as wafer-level chip-scale packaging, fan-out wafer-level packaging, copper pillar flip-chip packaging and 3D packaging.
Efficient chemical handling
Flexible process configuration
High throughput capabilities
Stable process results
One tool for all advanced packaging applications
By offering multiple process technologies such as photo resist, polyimide and PBO coating within one system, the ACS300 Gen3 delivers high efficiency. It also provides capabilities for up to five resist or four develop chemistries per module for optimal process flexibility. Moreover, the universal hotplate design eliminates the need for specific hotplates for different resist or PI types. The ACS300 Gen3 allows for simultaneous 200 and 300 mm wafer processing without mechanical changeover.
Attractive cost of ownership
The ACS300 Gen3 allows for efficient module stacking, thus saving costly space in the cleanroom. Up to twelve modules can be conveniently arranged on top of one another in a three-level modular system while the tool’s multiple chemical-saving features achieve further savings. Whether SUSS MicroTec’s proprietary GYRSET technology, a novel dispense technique or a chemical recirculation system - the tool uses chemicals economically and works in line with even the most rigid sustainability standards.
Excelling at throughput
When using the optional second robot system the ACS300 Gen3 reaches throughput rates up to 240 wph in a three-step process. An advanced process control system optimizes processing time: scheduling algorithms can be selectively swapped to ensure that time slots of bottleneck steps are fully utilized. Furthermore, features such as developer chemicals at elevated temperatures and flow modes reduce process times.
Consistent process monitoring leading to high yield
What makes the ACS300 Gen3 stand out is its high degree of process control. It is possible to continuously log process data for all relevant parameters such as temperature, flow, pressure, volume, purge rates, etc.. Data logging allows for precisely tuned process parameters, repeatable results and quick identification of potential weak points. Processes become more stable and repeatable, and yield can be significantly increased.
SUSS MicroTec 的 GYRSET 專利技術具有顯著的優勢。GYRSET的原理是，塗佈室在塗膠過程中同步旋轉，從而有效降低了旋轉基板上方的空氣湍流。在封閉的塗佈室中空氣比通常用溶劑 時更快速地飽和，使塗層乾燥緩慢，從而更均勻地分佈在基板上。這將大幅減少材料用量。
このプロセスでは、露光された基板に所定量の現像液を塗布し、適度に回転させて配分します。その際、現像液の表面張力によって、基板上に現像液が溜まった状態 (英語で「Puddle」) になります。現像時間が経過した後、現像液は高速回転によりウエハから飛ばされます。そして、脱イオン水でウエハを洗浄し、再び高速回転によって乾燥します。この手法のメリットは、現像液が少量しか必要でないこと、そして良好な現像結果が得られることです。
SUSS MicroTec’s proprietary GYRSET® technology helps to significantly improve spin coating process results by improving the conditions during coating. With the help of a rotating cover a turbulence-free atmosphere, highly saturated with solvents, can be created. This not only makes the outcome more independent from the ambient temperature and humidity. It also substantially reduces the amount of material required to coat a wafer therefore being beneficial for environmental sustainability.
The GYRSET® technology is highly suitable for processing thick resists.
