What was the revenue generated by the company's integrated metrology business in the second quarter of 2020
es.
Our plan to increase production capacity specifically in this period is started to accommodate the supply chain disruptions as well as customers demand for shorter lead times. As a result, we may experience some inventory volatility during the next few months yet without changing our long-term operational model. Our confidence in our new product portfolio and our ability to transform short-term pipelines into long-term growth engine dictate our operational goals currently independent of the current interim disruptions.
Turning now to our business highlights in the second quarter of 2020. Our performance continued to rely on breadth and depth of our customer mix, which was driven by five major customers, including three foundry logic customers and two large memory providers. As reflected in our customer mix, we are very proud to achieve two new share wins with both our stand-alone and integrated tools in China. This mix of customers highlights the growing demand for our solution in both memory and logic, which is affected by growing demand for NAND devices, as well as for wide range of logic devices, starting from 40 nanometer all the way down to 3 nanometer.
This outcome represent the overall positive momentum in the semiconductor industry that is dictated by the COVID-19 implication on the way we work, communicate, interact, stream data and rely on remote applications. In our service business, we are expecting meaningful growth this year, as we continue to offer proactive service packages to our customers to improve their install base productivity and metrology capabilities as well.
Beyond revenue contribution from service contracts and time and materials services, our goal is to significantly increase the overall contribution from value-added services that are developed specifically for our customers, enabling them to better utilize the aging install base and to extend their life cycle.
Finally, for this part, I would like to mention again, our strong operational model, which is the basis for our continuous growth and ability to invest in our development roadmap, even when facing uncertainties. The value of our products, along with Nova's unique offering and efficient manufacturing capabilities, support our profitability model and are reflected in our strong cash flow generation during the first six months of 2020, which was much higher compared with the same period last year. Embedded in our strategy, this cash position should accelerate our organic and non-organic plans specifically in this period.
Let me now provide some highlights as for our product portfolio and roadmap development progress. The first highlight to mention is our announcement from July 27, about new additions to our optical CD integrated solutions. The need for better in-die and in-wafer metrology performance in the most advanced logic and memory nodes is converging with our legit leadership in the integrated metrology market and supporting our aggressive future roadmap.
Our tight partnership with customers and our leadership position were both reflected strongly in the second quarter with record high revenues for integrated metrology across all front-end segments. The new announced platform, the i570 and ASTERA extends Nova's leadership in integrated metrology process control and targets the development and manufacturing of next-generation IC architecture.
The Nova ASTERA platform is the first of its kind in the industry, providing stand-alone level performance in a compact form factor of integrated metrology. The new platform utilizes multi-channel measurement, providing the best solution in the market in term of accuracy, precision, tool-to-tool matching and extendibility.
This platform is targeted to support the development of next-generation device technologies beyond 3 nanometer logic and 256 layers multi-deck 3D NAND nodes, and as such is expected to enter the market over the course of the coming years through R&D line first. The second new solution is Nova i570, single channel -- sorry, single channel SR platform, which is in the center
