The stand-alone selling prices are determined based on the prices at which we separately sell the systems, upgrades, components, spare parts, installation, maintenance, and service plans. For items that are not sold separately, we estimate stand-alone selling prices generally using an expected cost plus margin approach.
Management uses judgements in identifying performance obligations, determining stand-alone selling price (“SSP”) for each distinct performance obligation and allocating consideration from an arrangement to the individual performance obligations based on the SSP. The SSPs are determined based on the prices at which we separately sell systems, upgrades, components, spare parts, installation, maintenance, and service plans.

With this acquisition, Veeco is accelerating its entry into this market. We expect revenue in the Compound Semi market to grow in 2024. Sales in the Data Storage market increased slightly in 2023. Demand for our Ion Beam products is driven by cloud-based storage.
We are also seeing photonics opportunities in areas such as solar and MicroLEDs. We address the Data Storage market with sales of our Ion Beam technology. Demand for our Ion Beam products is driven by demand for cloud-based storage. Revenue from our Data Storage products increased in 2024 as compared to the prior year.
Additionally, our lithography systems for Advanced Packaging are used for packaging approaches such as fan out wafer level packaging and other advanced packaging applications, while our wet processing systems are used for Photoresist Strip, Solvent Cleans, and flux removal.
In the fourth quarter, we announced over $50 million in orders for our Wet Processing systems from a leading foundry, a HBM manufacturer, and OSATs. Our Advanced Packaging lithography systems are used for packaging applications such as fan out wafer level packaging and other advanced packaging solutions.
In cases where a revision is deemed appropriate, the remaining carrying amounts of the intangible assets are amortized over the revised remaining useful life. Intangible assets related to in-process research and development (“IPR&D”) projects are considered to be indefinite-lived until the completion or abandonment of the associated R&D efforts.
In cases where a revision is deemed appropriate, the remaining carrying amounts of the intangible assets are amortized over the revised remaining useful life. Income Taxes We estimate our income taxes in each of the jurisdictions in which we operate.
While our growth strategy is predominately focused on advanced node logic and memory applications, 2023 revenue has been strong for mature node applications in China. We continue to build momentum for our laser annealing solutions in advanced node logic by winning application steps and new customers.
While our growth strategy is predominately focused on advanced node logic and memory, LSA shipments to mature node customers have continued to increase in 2023 and 2024, predominantly driven by new greenfield fabs and capacity additions in China. We have two next generation laser annealing systems under evaluation at Tier 1 foundry and logic customers.
The decrease in net interest expense was primarily related to an increase of interest income of approximately $8.4 million due to higher interest rates for 2023 compared to 2022. Other Income (Expense) On May 19, 2023, in connection with the completion of a private offering of $230.0 million aggregate principal amount of 2.875% convertible senior notes, we repurchased and retired approximately $106.0 million in aggregate principal amount of our outstanding 2025 Notes, with a carrying amount of $105.4 million, for approximately $106.0 million of cash and 0.7 million shares of our common stock for the 2025 Notes.
The increase in net interest income was primarily related to an increase of interest income of approximately $2.3 million due to a higher interest rate environment for 2024 compared to 2023. 36 Table of Contents Additionally, the Company had a decrease of interest expense of approximately $0.7 million due to a reduction in convertible note and bank guarantee interest expenses. Other Income (Expense) For the year ended December 31, 2023, we recorded a loss on extinguishment of approximately $97.1 million related to the repurchase and retirement of approximately $206.0 million aggregate principal amount of our 2025 and 2027 Notes. Income Taxes Our income tax benefit for the year ended December 31, 2024, was $4.9 million, compared to income tax expense of $2.0 million for the prior year.
As it relates to the memory market, we announced that a Tier 1 memory customer placed several LSA orders for high volume production of High Bandwidth Memory (“HBM”) and advanced DRAM devices following a successful evaluation program, and we shipped several systems to this customer in 2023.
We also shipped and recognized revenue on our first NSA system to a leading logic customer in the fourth quarter. In the memory market, we continue to ship systems to a Tier 1 customer for high volume production of HBM and advanced DRAM devices.
Gross margins increased due to product mix of sales in the period, as well as favorable service spending.
Gross margins decreased principally due to unfavorable product mix of sales and higher service costs.
We generally do not enter into purchase commitments extending beyond one year. However, material shortages and supply chain challenges have caused some of these commitments to extend beyond one year.
