  • Publication number: 20250062258
    Abstract: The current invention offers a method for preparing an electronic integrated circuit (EIC) for the assembly of an optical engine. The method involves stacking a CMOS-based EIC wafer onto a short loop/interposer wafer through face-to-back bonding. This stacked configuration serves as a carrier for the thin CMOS wafers. Subsequently, the stacked wafers are thinned down to the desired height and undergo a via last process. In this process, the thick metal layer from the short loop/interposer wafer acts as an etch stop. The stacked EIC wafers can then be diced and attached to a photonic integrated circuit (PIC) wafer, resulting in the formation of an optical engine.

  • Publication number: 20240281472
    Abstract: An interactive search method is disclosed, utilizing a browser-based interface and generative artificial intelligence to enhance user search experiences. The method involves receiving an initial search query from a user, generating a proposed search result via hardware processors, and displaying the result to the user. To refine search accuracy, the method recommends clarifying questions, soliciting additional search parameters. Upon receiving an updated search query, the system interactively refines the initial query and displays an updated search result. This process allows for dynamic query adjustment and improved search result relevance in real-time.

  • Publication number: 20240281487
    Abstract: Enhanced search results are generated using multi-document summarization. A multi-document summarization system receives a search query from a user and retrieves a plurality of search result documents based on the search query. The summarization system generates a summary of each of the plurality of search result documents using distinct per-document summarization machine learning models, where the distinct per-document summarization machine learning models are trained on a training dataset. The summarization system synthesizes the summary of each of the plurality of search result documents into a single-consolidated answer responsive to the received search query. The multi-document summarization system formats the single-consolidated answer to include citations to the plurality of search result documents.

  • Publication number: 20240281446
    Abstract: An advanced search system leverages a pre-trained large language model to enhance user query responses. The system, equipped with hardware processors, a search query via an interface and accesses a pre-trained large language model designed to respond to the search query. The system fine-tunes the model to generate a task-specific generative model. The system employs the task-specific generative model to generate a search result to the search query and analyzes the search result based on a performance metric associated with the task-specific generative model. The system refines the task-specific generative model based on the analyzing of the search result.
