Non-Destructive Measurement of Bottom Width in Deep Trench Isolation Structures using IRCD Metrology

By Onto Innovation - 10 Sep, 2024 - Comments: 0

As scaling in semiconductor devices continues, the aspect ratios of deep trench isolation (DTI) structures have increased. DTI structures are used in power devices, power management ICs and image sensors as a method to isolate active devices by reducing crosstalk, parasitic capacitance, latch-up and allowing for an increase breakdown voltage of active devices. Measurement of these structures in... » read more

Power Stage Selection Considerations For High-Current Voltage Regulators

By Tammie Bard - 02 Jul, 2024 - Comments: 0

There are several key things to consider when selecting a power stage for high-current voltage regulators: What area does the power stage need to fit in? What is the continuous output current? What is the maximum peak current? This should not exceed the peak current rating of the power stage. What is the power loss for sustained output current? This can be calculated... » read more

Liquid Cooling And GaN: A Winning Combination

By Paul Wiener - 06 Jun, 2024 - Comments: 0

Data centers are facing an unprecedented transformation due to the surge in generative AI and other emerging technologies. A single ChatGPT session consumes 50 to 100 times more energy than a comparable Google search, escalating data center rack power requirements towards 200 kW or more, presenting serious challenges for operators. Cooling, in fact, takes up about 40% of the power requireme... » read more
