Latest Patents
One of Johnny Chew's latest patents involves a process to reduce substrate effects by forming channels under inductor devices and around analog blocks. This method includes several steps, such as selectively implanting Oor Oare into a silicon substrate to create a silicon-damaged silicon oxide region. Devices are then formed over the silicon substrate, close to this region, within at least one upper dielectric layer. A passivation layer is applied over the upper dielectric layer, which is subsequently patterned to create a trench that exposes part of the silicon substrate. The silicon-damaged silicon oxide region is selectively etched to form a channel that is continuous with the trench, effectively reducing substrate effects for the semiconductor devices. Additionally, a second method focuses on forming an analog device on a SOI substrate and selectively etching the silicon oxide layer to create a channel that partially underlies the analog device.
