Latest Patents

C S Teng's latest patents include a method for protecting nonsilicided surfaces from silicide formation. This invention addresses problems associated with forming silicided and nonsilicided structures on the same silicon substrate. By utilizing a spacer oxide masking technique, a protective spacer oxide layer is deposited over the silicon substrate surface. A silicide exclusion photoresist mask is selectively developed, allowing for the etching of the spacer oxide layer in regions where silicides are expected to form. This method effectively prevents silicide formation in masked areas, ensuring the integrity of the silicon substrate.

Another significant patent by Teng involves low voltage triggering silicon controlled rectifier (SCR) structures for electrostatic discharge (ESD) protection. These SCR structures are triggered by lightly doped diffusion junction breakdown voltages of approximately 4-10 V. This innovation eliminates the need for additional protection elements found in conventional SCR-based ESD protection circuits, thereby minimizing RC delay on the signal line and reducing circuit size. The SCR structures are compatible with existing CMOS processes and are scalable to submicron technology.
