2:10 PM - 2:35 PM - 3D sensing for consumer : the game changing interface


3D sensing is setting a new paradigm for human to device interaction in the smartphone space and is heading toward consumer electronics ubiquity. This newly embedded technology is built around a complex set of sub-components assembled to provide scene understanding beyond the traditional 2D video. Depth perception in this market is a difficult task knowing the constrained cost, space and power considerations. Join the Yole analysts and discuss the key challenges of underlying sub- components for 3D sensing in the consumer space.

2:35 PM - 3:00 PM - Reliable front end processing for VCSEL mass production


Taking the VCSEL technology to 6inch mass production is a challenge currently faced by many manufacturers. 3D sensing, including techniques such as face recognition, has start-ed a wave of investments across the world and launched the race to VCSEL mass production. In this race, careful design and processing sequence are keys to success.
In VCSEL manufacturing, a lot of emphasis has been put on mastering the epiwafer structure in order to gain control of the apertures. Additionally, to achieve reliable electro opti-cal performances and maximize the yield, careful front end processing remains critical. As the market demand increases, the transition to 6inch brings challenges on surface quality and uni-formity. For applications requiring arrays of VCSELs for higher combined output power, the threshold current and differential quantum efficiency have to be uniform from laser to laser within an array.
To address these challenges, Oxford Instruments Plasma Technology has designed a set of solutions, exposed in a breakdown of fabrication steps from the process flow of VCSEL, see figure 1. Associating strong process expertise and extensive device understanding, our latest processing solutions are focused on meeting key processing requirements to demon-strate 6inch capacity...

3:25 PM – 3:55 PM - Coffee Break and Networking



3:55 PM - 4:20 PM - Review of Consumer 3D Sensing Technologies


3D Sensing has been introduced on the consumer market a few years ago, but since late 2017 and the release of the iPhone X with Face ID a lot of companies have been investigating this space. 2018 will see at least two others smartphone OEM embedding 3D sensing for Face recognition: Oppo with the Find X and Xiaomi with the MI8 Explorer Edition. Integrating these modules is very challenging due to the limited space and the related cost.
Three main technologies are used in 3D sensing for consumer: Structured light, Stereo Vision, and Time of Flight. Based on pictures extracted from physical analyses of several modules from the leading players (pmdtechnologies, Intel, Apple…), the presentation will highlight the latest technologies trends for the key components (dot projector, NIR imager, VCSEL) and the evolutions in term of manufacturing process and package integration.

4:45 PM - 5:10 PM - Mass Production of NIR filters for 3D Sensing


When applications in mobile industrial sensing like gesture recognition, proximity and 3D sensing use a source such as an NIR LED or VECSEL to illuminate the scene, the detector in turn requires a high performance NIR filter to separate the signal wavelength from the background light.

Achieving the required accuracy and repeatability in deposition of the optical stacks at high throughput and low cost are already demanding manufacturing challenges, but the challenges are further compounded by the additional need to handle thin glass wafers typically in the 200 to 400 micron range safely. Controlling the introduction of any stress to avoid wafer warpage during the deposition process itself is also then essential not only for continued safe handling but also to avoid problems for downstream process steps such as dicing, and finally particle levels must be strictly controlled to main the required process yields.

The application of such optical coatings on a wafer level at the volumes and levels of process control required calls for a different manufacturing approach. Implementing optical deposition and process control know how on a fully automated platform with handling and tracking capability compliant with the semiconductor industry is the ideal manufacturing solution as the worlds of “Optics” and “Semiconductor” increasingly converge.

Typical process results on such a production tool will be presented to show how optimised sputter technology combined with in situ optical and plasma emission monitoring enable high deposition rates, optical accuracy and repeatability. System architecture will also be explained to show how full automation including handling, tracking and wafer flip are essential to achieve high productivity at low particle levels.
