Company profile
Yield Engineering Systems describes itself as a leading provider of technology solutions and process equipment for the semiconductor ecosystem and More than Moore applications, with a focus on surface and materials enhancement technologies. Its process equipment supports complex manufacturing steps used for emerging Artificial Intelligence, High Performance Computing, power-semiconductor, life-sciences, and mixed-reality hardware. The company's thermal-processing systems, deposition systems, and wet-etch and clean technologies are used in processing legacy and advanced-node silicon wafers, next-generation substrates, wafer-level and panel-level packages, and compound semiconductors. The same technology portfolio also addresses IoT devices, microLED and miniLED displays, and micro-fluidic consumables for genomics. Yield Engineering Systems states that its technologies are designed to optimize performance and cost of ownership and that its customer base ranges from startups to Fortune 100 companies across multiple markets. The company is headquartered in Fremont, California. Its corporate facts list 300 employees worldwide, including more than 220 engineers supporting semiconductor products and customer requirements. Yield Engineering Systems lists more than 100 patents, pending patents, and trade secrets in its intellectual-property portfolio. It also states that more than 1,000 tools have been delivered to more than 100 fabs worldwide. Its operating footprint includes global headquarters, R&D, and new-product introduction in Fremont, an Advanced Technology Center and Wet Processing Group in Chandler, manufacturing in Sulur, engineering and R&D in Bengaluru and Coimbatore, and sales and service locations in Taiwan, South Korea, Japan, and Germany. In 2025, the company announced the shipment of its first commercial VeroTherm Formic Acid Reflow tool from the Sulur, Coimbatore manufacturing facility to a global semiconductor manufacturer. It also announced 2025 orders for dry and wet process systems supporting glass-substrate panel-level manufacturing for next-generation AI and HPC packaging, along with orders for VeroTherm, VeroFlex, and VertaCure systems used in advanced packaging and high-performance AI applications.
Exhibits
Yield Engineering Systems groups its equipment into Dry Process, Wet Process, Radix Lab to Fab Products, and Strategic Technology Platforms. The listed Dry Process portfolio includes VeroTherm FAR XP, VertaCure XP G2, VertaCure PLP, VeroFlex FAR PLP, UltraCoat, VertaPrime PLP, and VertaBond. The listed Wet Process portfolio includes the TersOnus Platform, SURE Wet Processing Tool, Chemical Delivery Units, and TersOra Edge Zone Removal. Radix Lab to Fab products include the G Series, RFS, EcoClean, TA Series, EcoCoat, and PB Series, while strategic technology platforms include Single Panel Vacuum Processing, Integrated Metrology, Novel Adhesion Technologies, and High Temperature Processing. The company's equipment is used to enable advanced packaging for High Performance Computing and Artificial Intelligence applications. VeroTherm FAR can be used for solder balls, C4 bumps, and microbumps needed for advanced packages. VertaCure provides a cure process for both build-up layers and the interposer. VertaPrime enhances the bonding required between build-up layers and the substrate core. TersOra uses an edge-zone removal process to produce uniform edges in advanced-package build-up layers. The TersOnus Platform can be specified for precise through-glass-via etching in substrates to provide enhanced connectivity in microelectronics. TersOnus Platform Electroless deposits metals used for connectivity in advanced-packaging build-up layers. For glass-panel AI and HPC packaging, the company announced dry and wet tools supporting curing, cleaning, reflow, and deposition processes for high-throughput glass-based 2.5D and 3D integration. VeroTherm and VeroFlex reflow systems were also described for 3D stacking of memory and logic chips for high-performance AI accelerators, including sub-10 µm fluxless solder reflow with thermal uniformity and reliability targets. VertaCure G3 systems are described for advanced semiconductor packaging with precise low-temperature curing, annealing, and degassing in next-generation 2.5D and 3D packaging technologies. The RapidCure tool combines UV and direct thermal exposure and is described as significantly reducing process cycle time for fan-out wafer-level packaging. EcoCoat is described as producing a highly uniform interface layer for stable coupling chemistry used in chemical synthesis on wafer or glass substrates. The TersOnus TGV system is presented for panel-level product manufacturing, while VeroTherm Formic Acid Reflow is designed for sub-10-micron micro-bump structures using fluxless solder and mass reflow. The overall product set therefore connects thermal processing, deposition, curing, reflow, wet processing, cleaning, adhesion, metrology, edge-zone removal, and through-glass-via processing across wafer-level and panel-level advanced packaging flows.
