Advanced Laser Direct Imaging
The Advance Laser Dynamic Imaging (ALDI) system is designed based on Aiscent's proprietary micro-mirror based dynamic imaging and scanning system. This is an not the simple ordinary DMD device imaging scheme, ALDI system has a special designed DLP optical engine system which enables it to improve the performance in many area as compared to the conventional method.
Current technology has proven to be inadequate for the more precise images needed in the many applications. As the need for finer features and higher resolution continues, the current systems are becoming increasingly ineffective especially for the sub-10 micron feature size. As a result, the resulting pattern often shows the effect of digital pixilation and looks rather ridged.
Upgradable Multi-Optical Engine Scanning Concept
Our modular imaging technology allows different imaging heads to be retrofitted as your requirements change. Depending on your throughput requirements and your budget, we can build a system that meet your current conditions and upgrade it in the future to meet your needs from time to time.
Line Edge Smoothing Technology
A creative technology using special DMD scanning method coupled with special MLSFA (Micro Lens with Spatial Filter Array) enable ALDI system to produce better line edge performance and resolution compared with other direct writing solutions.
ALDI system generates images in real time mode, allowing dynamic adaptation to scale and rotate the pattern in the computer system. Registration errors caused by flatness variations of the substrate and the error of the stage moving is improved by additional software to compensate for any variation in the mechanical structures or the environmental parameters, and it also compensates the registration errors caused by distortion error of the substrate. These deviations are compensated for each side individually, providing better side to side registration performance.
“Chip-by-Chip” Alignment and Scaling Technology
ALDI system allows internal scaling points to be selected allowing each chip on a single panel to be scaled individually. The same function apply to multiple panels in a single batch, each panel will be aligned and scaled individually in the software system.
