A criterion to describe the turn-to-turn discharge of the secondary winding in Tesla transformers is presented. Factors which have influences on the turn-to-turn insulation of the winding such as the wire diameter, the wire distance, the void size, the purity of transformer oil and the insulation strength of the wire are researched based on this criterion. By theoretical calculation, the electric...
The time dependent dielectric breakdown (TDDB) of four organo-silicate-glass (OSG) films with varying porosity (k=2.0, 2.5, 2.8 & 3.0) was investigated using metal-insulator-semiconductor (MIS) capacitors. Without any barrier, the dielectrics show lower TDDB-lifetimes under Cu ion drift conditions, where the OSG-2.8-film exhibits a better performance. Other results are that the damage caused by...
Using a dedicated test vehicle (low-k planar capacitor) for studying the intrinsic properties of low-k materials and using standard single damascene 50 and 90 nm ½pitch test vehicles, differences in reliability behavior between intrinsic and integrated SiOCH porous low-k materials were investigated. The studied parameters were leakage current, breakdown field, distributional shape of failure times...
A novel anti-ESD RF SOI LIGBT with buried P-type layer (BPL) was proposed for improvement of its forward block characteristic. The proposed anti-ESD BPL RF SOI LIGBT consists of an additional buried P-type layer inserted between buried oxide layer and N-drift region based on the conventional RF SOI LIGBT structure and a built-in self-ESD-protection structure introduced in P-well region. When the proposed...
