Milestone marked at CompoundTek’s SiPh Test Centre with On-Wafer Test breakthrough, sees 40% system throughput improvement

Proprietary Test Executive System capitalises on artificial intelligence, machine learning and big-data analytics

Singapore, 27 July 2020 – CompoundTek Pte Ltd. (CompoundTek), a global foundry services provider in emerging silicon photonics (SiPh) solutions, have announced a breakthrough in Silicon Photonics Wafer Test with its proprietary Test Executive Software (TES). Incorporating the use of Artificial Intelligence (AI) and Machine Learning, the TES demonstrates an improved throughput of the system and the subsequent data analysis by up to 40 per cent. This pioneering solution allows the user to achieve a fully-automated wafer test with minimum human intervention, effectively identifying and optimising key test parameters to subsequently reduce test and engineering analysis times needed.

TES marks a major milestone for the company’s dedicated SiPh Testing Centre of Excellence. Launched early this year, the open-source SiPh test hub is Southeast Asia’s first-of-its-kind facility focused on production and engineering test services accessible to commercial industry players. Poised to advance CompoundTek’s goals of accelerating marketplace adoption of SiPh, TES reinforces the increasing popularity of this niche semiconductor technology as an alternative to displace traditional electrical interconnects. SiPh is also sought for in a broad range of rapidly evolving applications including lidar, quantum computing, and bio-sensing. Today, however, the integration of optical components on a chip creates a host of new challenges in wafer-level probing of SiPh devices.

High cost and efficiencies represent the foremost challenges to mass-market adaptation, with large volumes of device-performance data required to carry a design from concept to qualification and subsequently into production.   

Recognising this and the need for a performing test executive, the company’s TES, benchmarked with a 40 per cent improvement in test throughput and result-analysis time, surpass commercially available software. It additionally validates the powerful use of Big Data analytics to streamline test items in furthering improvements in test throughput, and paves the way in strengthening CompoundTek’s technology roadmap and customer offerings.

Launched in 2017, Singapore-based CompoundTek has more than 20 global commercial customers, and over 20 research institutes and universities in various applications such as telecommunications, automotive radar, data communications, bio-sensing, artificial intelligence, quantum computing and smart sensors.
