About System Plus

• This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price of theSTMicroelectronics Proximity Sensor & Flood Illuminator in Apple iPhone X.

• Located in the front above the main speaker, the proximity sensor & flood illuminator is packaged using optical LGA. The device is a custom version for Apple. In the past, STMicroelectronics has already release a custom proximity sensor two times smaller (2.80 x 2.40 mm) than the devices in it’s portfolio. This new version came along with a flood illuminator used in the true depth system. The sensor is still based on FlighSenseTM technology.

• In this report, the complete microsystem is analyzed from the two illumination device which are a Vertical-Cavity Surface-Emitting Laser (VCSEL) to the collector based on the Single Photon Avalanche Diode (SPAD) developed by STMicroelectronics. The report includes a complete cost analysis and price estimation of the device based on a detailed description of the package, the ToF detector, the VCSEL and the other VCSEL for the flood illumination.

• It also features a complete technology comparison with the STMicroelectronics ToF portfolio since the first generation, the VL53L0X the VL6180X, and the last custom proximity sensor from the Apple iPhone 8.
