Latest Patents

Hwang's latest patents include a method of fabricating a semiconductor memory device. This method involves preparing a semiconductor substrate divided into a cell array region and a core and peripheral region. Signal lines are formed in a lower layer within the cell region, followed by the creation of an insulation layer. Additionally, signal lines connected to the cell region signal lines are formed on the insulation layer of the peripheral region. A capping layer is then applied, which is etched to expose the lower layer of the cell array region. An etch stop is formed on the lower layer and the core and peripheral region.

Another notable patent involves methods of forming integrated semiconductor devices that contain field oxide and channel-stop isolation regions. This process includes implanting first conductivity type impurities into a semiconductor substrate to create channel-stop isolation regions. Field oxide isolation regions are then formed at the locations of these implanted regions. A conductive layer is patterned over the field oxide isolation regions, which serves as a landing pad layer during the formation of second channel-stop isolation regions. This innovative approach helps reduce leakage currents and improve the refresh characteristics of memory devices.
