Title: Innovations of Chi Nan Brian Li
Introduction
Chi Nan Brian Li is a prominent inventor based in Austin, TX. He holds a total of 8 patents that showcase his contributions to the field of semiconductor technology. His work has significantly impacted the design and manufacturing processes of semiconductor devices.
Latest Patents
One of his latest patents is a method for making a semiconductor device with reduced spacing. This innovative approach involves forming floating gates in two separate polysilicon deposition steps, resulting in distinct portions. The first formed portions are strategically placed between isolation regions. A thick insulator is then created over these regions and floating gate portions. The insulator is patterned to leave fences over the isolation regions, followed by a thinning process that applies an isotropic etch to these fences. This results in polysilicon sidewall spacers that become the second portion of the floating gate. These enhancements significantly increase the capacitance to the subsequently formed control gates, thereby reducing the gate voltage required for programming and erasing through a robust process.
Another notable patent by Chi Nan Brian Li is a method of forming a semiconductor device and the structure thereof. This method includes providing a silicon semiconductor substrate, forming a dielectric layer on its surface, and creating a silicon gate electrode over this layer. The process continues with recessing the dielectric layer under the gate electrode, filling the recess with a discrete charge storage material, and oxidizing portions of both the gate electrode and the semiconductor substrate.
