Revasum, Inc. announced it has secured the first purchase order for two 6EZ Silicon Carbide (SiC) Polishers from a major global semiconductor wafer manufacturer. The first tool will ship to the customer's European facility in August 2021, followed by the delivery of a second tool during the first half of 2022. The customer is also forecasting requirements for additional tools during the 2022 fiscal year. The 6EZ is the Company's polisher, designed to process SiC substrates. The machine offers fully-automated cassette-to-cassette wafer handling, with an integrated cleaning module, allowing dry-in/dry-out operation. The equipment is easily configured to polish 150mm or 200mm SiC wafers, which enables maximum flexibility in addressing both increased global demand for 150mm wafers and the anticipated production ramp of 200mm wafers in the near future. Key SiC applications include autonomous and electric vehicles, 5G infrastructure, solar inverters, and power devices. This order brings the total equipment backlog as of June 1st, 2021 to USD 7.4 million. Other revenue backlog as of the same date is USD 2.1 million. Backlog is defined as confirmed purchase orders that have not yet shipped.
