The present invention discloses a method for cleaning substrate without damaging patterned structure on the substrate using ultra/mega sonic device, comprising: applying liquid into a space between a substrate and an ultra/mega sonic device; setting an ultra/mega sonic power supply at frequency f1 and power P1 to drive said ultra/mega sonic device; after micro jet generated by bubble implosion and before said micro jet generated by bubble implosion damaging patterned structure on the substrate, setting said ultra/mega sonic power supply at frequency f2 and power P2 to drive said ultra/mega sonic device; after temperature inside bubble cooling down to a set temperature, setting said ultra/mega sonic power supply at frequency f1 and power P1 again; repeating above steps till the substrate being cleaned.
US11848211B2 Semiconductor device, method for manufacturing semiconductor device, inverter circuit, drive device, vehicle, and elevator
A semiconductor device according to an embodiment includes: a silicon carbide layer; a silicon oxide layer; and a region disposed between the silicon carbide layer and the silicon oxide layer and having a nitrogen concentration equal to or more than 1×1021 cm−3. A nitrogen concentration distribution in the silicon carbide layer, the silicon oxide layer, and the region have a peak in the region, a nitrogen concentration at a first position 1 nm away from the peak to the side of the silicon oxide layer is equal to or less than 1×1018 cm−3 and a carbon concentration at the first position is equal to or less than 1×1018 cm−3, and a nitrogen concentration at a second position 1 nm away from the peak to the side of the silicon carbide layer is equal to or less than 1×1018 cm−3.
US11848208B2 Method for forming semiconductor device structure
A method for forming a semiconductor device structure is provided. The method includes forming a first spacer over a substrate. The method includes partially removing the first spacer to form a gap dividing the first spacer into a first part and a second part. The method includes forming a filling layer covering a first top surface and a first sidewall of the first spacer. The filling layer and the first spacer together form a strip structure. The method includes forming a second spacer over a second sidewall of the strip structure. The method includes forming a third spacer over a third sidewall of the second spacer. The third spacer is narrower than the second spacer.
