Latest Patents

One of her latest patents is focused on methods for fabricating DRAM semiconductor devices that include silicon epitaxial and metal silicide layers. This patent describes a DRAM semiconductor device and a method for its fabrication. The method involves forming a silicon epitaxial layer on a source/drain region of both the cell region and the peripheral circuit region using selective epitaxial growth (SEG). This process results in the formation of a raised active region. Additionally, a metal silicide layer and a metal pad are created on the silicon epitaxial layer in the source/drain region of the cell region. This innovation allows for the formation of a source/drain region as a shallow junction region, which reduces leakage current and lowers contact resistance.

Another notable patent involves a measurement circuit and method for serially merging single-ended signals for analysis. This invention provides a measurement circuit that detects DP and DM signals from a device under test (DUT). The circuit removes the DC portion from both signals, stores them in memory, and then serially merges the two data signals without distortion. The merged signal is divided at predetermined intervals, allowing for the generation of eye diagram data and analysis data, which includes crossover voltages, rising time, and falling time.
