T-MAP 3D

Time-domain Optical Coherence is the most robust solution for TSV depth, bow & warp and individual layer TTV of a stack measurement as each interface is detected in the right order over a larger range than spectral interferometry. The only limitation is the minimum measurable thickness due to the high coherence length of the IR LED source.

Blog post from Philippe Gastaldo,  Product and R&D Director, UnitySC.

As the automotive electronics market continues to grow, spurred by developments such as semi-autonomous and fully autonomous vehicles, the demand is increasing for power semiconductor components with sophisticated conversion schemes that decrease power consumption and heat. To address these needs, power semiconductor manufacturers are turning to thin wafers.

Today’s power semiconductors are manufactured primarily on 200-mm wafers that range in thickness from 50 to 100 µm, but their roadmaps are targeting wafers as thin as 1 µm. These wafers are thinned on the backside by mechanical polishing. Defects resulting from the polishing process include grinding marks, grinding failures resulting in edge chips, star cracks and comets formed by edge particles that get caught in the grinding wheel, embedded particles, cleavage lines, and a variety of other imperfections [Evaluation Engineering].

Article published by UnitySC in Chip Scale Review (July-Aug 2017, Volume 21, Number 4)

With the increase of costs, delays and complexity at the most advanced frontend silicon technology nodes, advanced packaging process control solutions have become a key differentiator for achieving next-generation requirements, and thereby continued sustainability in the semiconductor industry. Within the advanced packaging realm, fan-out wafer level packaging (FOWLP) is gaining momentum due to its high integration, extreme flexibility, performance enablement and cost advantages, compared with more conventional assembly technologies.

Despite the wide adoption of FOWLP during the last few years, there are several challenges remaining about the industrialization of the process. For example, regardless of the FOWLP methodology used, the epoxy molding compound (EMC) is still a potential source of issues, with challenges in total thickness variation (TTV) management, package warpage and die shift. From a pure metrology perspective, the EMC thickness measurement may also be a challenge, because the epoxy material typically becomes opaque above a certain thickness and cannot be measured in the visible or infrared domains by conventional optical metrology techniques.

In this article, we introduce the various metrology technologies used to control the FOWLP process and review the main metrology measurements required during high-volume manufacturing. Additionally, we explore the advantages of using an inline, integrated 2D/3D metrology solution to characterize the FOWLP fabrication process using the chip-first/face-down approach.
