Latest Patents

Yuan Lei's latest patents include a groundbreaking method for semiconductor device modeling using input pre-processing and transformed targets for training a deep neural network. This innovative approach allows for the modeling of semiconductor devices by gathering measurements of test transistors, including gate and drain voltages, as well as transistor width and length. The training data is enhanced through an input pre-processor that can apply logarithmic transformations or perform Principal Component Analysis (PCA). Instead of using the measured drain current as the target for training, a target transformer converts the drain current into a transformed version, such as its derivative with respect to gate or drain voltages. The deep neural network's weights are adjusted during training by minimizing a loss function based on the comparison between the network's output and the transformed drain current.

Another notable patent is the method and system for integrated circuit (IC) layout migration integrated with layout expertise. This patent addresses the migration of an existing IC layout to multiple target layouts for different semiconductor processes with varying design rules. The existing layout file is parsed to generate a layout database file, which includes essential data items such as boundaries, paths, text, and cell instances. A layout engineer can select functions from a design toolkit to write reusable code, allowing for efficient adjustments to placements and routing based on the target design rules.
