A semiconductor chip comprises low voltage complementary metal oxide semiconductor (CMOS) sectors and high voltage lateral double diffused metal oxide semiconductor (LDMOS) sectors and at least one transistor within at least one of the low voltage CMOS sectors. The transistor has a semiconducting channel region within a substrate. A gate conductor is above the top layer of substrate, and the gate conductor is positioned above the channel region. A source/drain region is included in the substrate on a first side of the gate conductor and a lateral source/drain region is included in the substrate on a second side of the gate conductor opposite the first side. The lateral source/drain region is positioned a greater distance from the gate conductor than the source/drain region is positioned from the gate conductor. The embodiments herein also include a source/drain ballast resistor in the substrate between the lateral source/drain region and the gate conductor.
