• Machine Imaginative and prescient helps in quite a few course of steps in semiconductor manufacturing
• Use instances equivalent to high quality management, positioning, and alignment duties or monitoring will be automated with machine imaginative and prescient
• Munich-based MVTec Software program GmbH develops highly effective software program merchandise required for this objective
Munich, August 3, 2023 – The worldwide semiconductor manufacturing capacities are constantly increasing. Nevertheless, the manufacturing processes on this business are complicated and embody greater than 1,000 totally different steps. In consequence, the event of manufacturing capacities is equally difficult and delicate. Thus, there’s a want for applied sciences that may be quickly applied and tailored, whereas concurrently enhancing manufacturing effectivity. A key know-how right here is machine imaginative and prescient. Its important benefit lies in the truth that within the high-precision manufacturing of semiconductors, the quite a few crucial inspection and alignment processes will be automated and carried out with excessive precision. With its software program merchandise HALCON and MERLIC, the Munich-based firm MVTec Software program GmbH provides the machine imaginative and prescient software program which advantages the various course of steps of semiconductor manufacturing.
Highly effective machine imaginative and prescient applied sciences for semiconductor manufacturing
In practically all semiconductor manufacturing eventualities, there’s a minimum of one step the place the product is inspected for useful or beauty defects. In a extremely automated manufacturing setting, high quality inspection utilizing machine imaginative and prescient provides quite a few benefits over handbook inspection: machine imaginative and prescient is way sooner, delivers goal and reproducible outcomes, and the standard of the inspection doesn’t run the danger of degrading attributable to fatigue or the monotony of the duty. Deep studying applied sciences like anomaly detection are additionally appropriate for this objective. For instance, it permits automated floor inspection for detecting and segmenting defects.
In terms of high quality inspection, it’s important to examine for each dimensional accuracy and defects. Machine imaginative and prescient permits for the measurement of edges with subpixel-accuracy, alongside traces or circle segments, in just a few milliseconds. With 2D measurement it is usually doable to examine objects of a selected geometric form. As well as, there are strategies out there for 3D measurement, together with the usage of disparity photos, distance photos, or the reconstruction of 3D floor coordinates by numerous strategies.
Packaging: The final steps to the completed chip Aside from high quality inspection, discovering and aligning wafers and chips is one other utility the place machine imaginative and prescient can present very efficient assist. That is the place subpixel-accurate shape-based matching comes into play. The know-how precisely and robustly detects objects in actual time. This works even when objects are rotated, scaled, perspectively distorted, regionally deformed, partially lined or outdoors the picture.
The added worth provided by the know-how is illustrated by the instance of the packaging manufacturing step, the place the chip is encapsulated in a plastic housing. The only dies are first inserted into the housing. After that, they’re linked to the related contacts of the corresponding package deal in a number of steps. The precise positioning of dies throughout the package deal is an important step for enabling subsequent processing. For this objective, shape-based matching strategies are appropriate. In apply, the mannequin of a die is educated, for instance through CAD knowledge. By matching the coaching knowledge with the unique picture, the die is positioned and its place within the plastic housing is calculated, enabling additional processing.
The listed manufacturing steps have been chosen as examples for example the added worth of machine imaginative and prescient. Furthermore, as “the attention of semiconductor manufacturing”, the know-how alongside the entire course of chain. Particularly in high quality assurance and packaging, high-performance machine imaginative and prescient software program makes a invaluable contribution to environment friendly manufacturing.
