 July 2020, pursuant to which Samsung agreed to provide us with certain development support, an intellectual property license, and mass production set up support to enable us to develop and produce 5G chip sets for our customers. The development support, technology licensing and other services provided to us under the Alpha Agreements and Vendor Agreements will complete and/or replace the work originally begun under the Samsung Agreement and will allow us to achieve materially identical results with regards to developing and producing 5G chipsets as the Samsung Agreement. Accordingly, the Samsung Agreement has been terminated.

Manufacturing

We employ a fabless semiconductor business model and use third-party foundries and assembly and test vendors to manufacture, assemble and test our semiconductor solutions. Our main foundry vendors are Samsung Foundry, and United Microelectronics Corporation (“UMC”). From Samsung Foundry, we currently use 28nm mixed-signal and digital Complementary Metal-Oxide-Semiconductor (“CMOS”) production processes for 4G baseband modem, and 8nm technology for 5G baseband modem products. which are under development. The use of these commercially available standard processes enables us to produce our products more cost-effectively and, by migrating to lower process geometries, we expect to achieve advantages in cost, size and power consumption. Particularly, given the fact that foundry companies, which can provide the leading-edge foundry technology for fabless semiconductor companies to access, are very few and practically limited to TSMC and Samsung Foundry in this market, it is very important for us to establish close relationships with such foundry companies. Currently, the Company and Samsung Foundry enjoy a mutually beneficial foundry relationship providing secure access to leading-edge technology and manufacturing capacity as our 5G business ramps.

From UMC, we currently use 110 RF production process for 4G RF only, and 40nm RF, mixed-signal and digital CMOS production processes for 4G baseband, 4G RF and 5G RF. From TSMC, we currently use 40nm RF, mixed-signal and digital CMOS production processes for 4G RF only.

We use Hana Micron, Stats ChipPAC, and Advanced Semiconductor Engineering, Inc., (“ASE”) for most of our assembly and testing requirements on a purchase order basis. We conduct extensive simulation, practical application and standardized test bed studies to validate and verify our products.

We closely monitor the production cycle from wafer to finished goods by reviewing electrical
