A process for dimerizing and oligomerizing an olefin into a distillate fuel manages the dimerization exotherm by diluting the olefin with a paraffin that is inert in the dimerization. The olefin stream can also be separated and fed to multiple dimerization reactors to further reduce the heat generated. The ethylene feed can also be cooled before entering the dimerization reactor. The paraffin is obtainable from a saturated oligomeric effluent.

The application discloses a high-density DreaMOS device and a manufacturing method thereof. The high-density DreaMOS device comprises a semiconductor structure layer, a gate oxide layer matched with the semiconductor structure layer and a gate electrode. The semiconductor structure layer comprises an epitaxial layer, a source region, a well region, a well region contact region, a drain region extension region and a drain region formed in the epitaxial layer. A channel doping region is further formed in the epitaxial layer. The channel doping region is distributed at least in a lower region and a side region of the gate electrode. The channel doping region is connected with the source region, the drain region extension region and the well region respectively. The on-resistance of the high-density DreaMOS device provided by the embodiment of the application is reduced by 85%, and the current density is 4.5 times of that of a conventional LDMOS device.
