This invention provides a method for forming alignment marks in semiconductor processes. Trenches are simultaneously etched in both the device region and the alignment region. After filling the trenches in the alignment region with a dielectric layer, a cap epitaxial layer is formed in both the device region and the alignment region. By controlling the trench width and the thickness of the cap epitaxial layer in the alignment region, the cap epitaxial layer is not completely closed above the dielectric layer. The gap in the cap epitaxial layer serves as the alignment mark on the front side of the semiconductor substrate, and the bottom of the dielectric layer serves as the alignment mark on the back side of the semiconductor substrate. This method avoids the attenuation or disappearance of alignment signals during the planarization process after epitaxy, and does not increase alignment errors. It also ensures the clarity and accuracy of the front and back alignment signals, improving process reliability.

This invention relates to the field of artificial intelligence technology, providing an AI-based intelligent question-answering method, system, and storage medium for robots. The method includes: acquiring the user's original speech and auxiliary recognition information; extracting acoustic information and stuttering type; semantically cleaning and reconstructing the original speech to generate target semantic text; when stuttering type is present, identifying stuttering influencing factors based on acoustic and auxiliary recognition information, and determining a speech activity detection threshold; loading personalized interaction data based on stuttering influencing factors and stuttering type labels to synthesize response speech; detecting the original speech based on the speech activity detection threshold and outputting the response speech to complete the question-answering interaction. This invention solves the problems of speech truncation, semantic misunderstanding, and impersonal interaction in existing technologies, achieving complete acquisition, accurate understanding, and humanized responses to the speech of stuttering users.

The invention discloses an integrated biological photoelectrode with an active noise reduction function. The integrated biological photoelectrode with the active noise reduction function comprises a light emitting diode, an active noise control line and at least one microelectrode. By arranging the light-emitting diode and the microelectrode, the nerve cells can be subjected to light stimulation through the light-emitting diode, so that the nerve cells move to generate nerve impulse signals, and the nerve impulse signals are collected through the microelectrode to be processed, analyzed and studied; by arranging the active noise control line, an electric signal can be applied to the active noise control line, so that the noise influence generated when the light emitting diode works is counteracted, the active noise reduction function is achieved, and it is guaranteed that the integrated biological photoelectrode detects clearer signals. The method is widely applied to the technical field of biosensing.

This utility model discloses an electronic fishing float that facilitates wireless charging, comprising a lower float body. A first threaded groove is formed on the top of the outer surface of the lower float body. A threaded sleeve is threaded onto the outer surface of the first threaded groove, and an upper float body is fixedly connected to the upper surface of the threaded sleeve. This electronic fishing float, which facilitates wireless charging, uses the first threaded groove, threaded sleeve, first sealing ring, and second sealing ring. The lower float body is connected to the upper float body via the first threaded groove and threaded sleeve, which not only facilitates user disassembly and assembly but also ensures the overall stability and sealing of the fishing float during use. The first and second sealing rings are in close contact, and the sealing strip and sealing groove fit together to form a double sealing structure, effectively preventing water from entering the interior of the fishing float, protecting the internal electronic components from damage, significantly extending the lifespan of the fishing float, reducing user costs, and improving the overall reliability of the fishing float.
