Abstract: The present invention facilitates semiconductor fabrication by providing methods of fabrication that apply tensile strain to channel regions of devices while mitigating unwanted dopant diffusion, which degrades device performance. Source/drain regions are formed in active regions of a PMOS region (102). A first thermal process is performed that activates the formed source/drain regions and drives in implanted dopants (104).

A second thermal process is performed (110) that causes the capped poly layer to induce strain into the channel regions of devices. Because of the first thermal process, unwanted dopant diffusion, particularly unwanted p-type dopant diffusion, during the second thermal process is mitigated.

Abstract: A drain-extended metal-oxide-semiconductor transistor (40) with improved robustness in breakdown characteristics is disclosed. Field oxide isolation structures (29c) are disposed between the source region (30) and drain contact regions (32a, 32b, 32c) to break the channel region of the transistor into parallel sections. The gate electrode (35) extends over the multiple channel regions, and the underlying well (26) and thus the drift region (DFT) of the transistor extends along the full channel width. Channel stop doped regions (33) underlie the field oxide isolation structures (29c), and provide conductive paths for carriers during breakdown. Parasitic bipolar conduction, and damage due to that conduction, is therefore avoided.
