“…Recently, epitaxial p-pillar layer of 37 !lm depth in the trench has been formed, and on-resistance has been reduced to about 11 1 0 of a conventional MOSFET. This SJ-MOSFET has the on-resistance of 7.8 mQcm 2 at the breakdown voltage of 600 V class [10]. Figure 13 shows a road map of on-resistance reduction in SJ-MOSFETs.…”

“…These devices use deep trench etching and epitaxial re-growth for making the alternate doped pillar structure. By an optimized trench filling epitaxial growth technique, 680V devices with an extremely low R ON-SP of 7.8 mΩcm have been reported by Denso [11]. Another alternative is the deposition of two epitaxial layers (n and p-type) on the vertical walls of deep trenches, which was first reported by Infineon [12], showing a theoretical 50% reduction of R ON-SP in comparison with a 600V CoolMOS.…”

“…Nous avons envisagé ce type de structure car les méthodes de fabrication industrielle actuelles se basent sur des implantations fortes énergies [47], [48], ou sur une succession d'épitaxies et d'implantations [34], [41], [49], [50], ou sur une gravure profonde suivie d'une croissance épitaxiale [32], [33], [51]. Ces différentes techniques étant coûteuses, il était intéressant de proposer une solution adaptée à une tenue en tension de 1200 V. La principale différence avec la Superjonction conventionnelle est le profil de dopage de la colonne P ( Figure II.12).…”
