OneChip’s unique, regrowth-free, Multi-Guide Vertical Integration (MGVI) platform eliminates the need for multiple epitaxial growth steps. This enables OneChip to decouple epitaxial growth and wafer processing, while outsourcing both functions to independent, pure-play commercial foundries. Under this fabless model, OneChip has been working with GCS to process its OneChip-designed 4-inch InP-based wafers. This leverages the infrastructure and expertise GCS has gained through serving high-volume radio frequency (RF) electronics markets.

GCS’s foundry services, based on its state-of-the-art Opto and Heterojunction Bipolar Transistor (HBT) processes in Indium Phosphide, are a perfect match to OneChip’s fabless model, which is built around its regrowth-free PIC platform. Further, GCS’s Opto and HBT and OneChip’s PIC technologies share the same process and provide a unique Opto-Electronic Integrated Circuit (OEIC) platform. This, for the first time, enables both electronic and photonic integration on one substrate, within the same commercially available fabrication process.

In a separate release:

OTTAWA -- OneChip Photonics today announced that it is working with IQE, the world’s leading independent provider of III-V semiconductor epitaxy services, to grow the epitaxial (epi) structures, which OneChip uses to produce its Photonic Integrated Circuits (PICs) for the Data Center Interconnect (DCI) and Passive Optical Network (PON) markets.

This enables OneChip to decouple epitaxial growth and wafer processing, while outsourcing both functions to independent, pure-play commercial foundries. Under this fabless model, OneChip has been working with IQE for the production of its OneChip-designed 4-inch indium phosphide (InP)-based epitaxial wafers. This leverages the infrastructure and expertise IQE has gained over 25 years, supporting the advanced semiconductor industry with its pioneering outsourcing model.

Valery Tolstikhin, Founder and CTO of OneChip Photonics, said, “The iron-doped, semi-insulating 4-inch InP substrates, and the metal organic chemical vapour deposition (MOCVD) growth technique, required for OneChip’s epi-wafers, are the same as those used by IQE for its high-volume epitaxy products, so we have strong economies of scale in working together. IQE is recognized as a leading independent, pure-play epi-wafer foundry, which not only provides world-class services, but also perfectly fits into our fabless PIC manufacturing model.”
