  • Patent number: 9240457
    Abstract: An IGBT transistor includes a drift region, at least one body region housed in the drift region and having a first type of conductivity, and a conduction region, which crosses the body region in a direction perpendicular to a surface of the drift region and has the first type of conductivity and a lower resistance than the body region. The conduction region includes a plurality of implant regions, arranged at respective depths from the surface of the drift region.
    Type: Grant
    Filed: January 23, 2014
    Date of Patent: January 19, 2016
    Assignee: STMICROELECTRONICS S.R.L.

  • Patent number: 7675135
    Abstract: Instabilities and related drawbacks that arise when interruptions of a perimetral high voltage ring extension implanted regions (RHV) of a main junction (P_tub 1, (P_tub2, . . . ) of an integrated device must be realized may be effectively prevented. This important result is achieved by an extremely simple expedient: whenever an interruption (I) of the high voltage ring extension must be created, it is not realized straight across it along a common orthogonal direction to the perimetral implanted region, on the contrary, the narrow interruption is defined obliquely or slantingly across the width of the perimetral high voltage ring extension. In case of a straight interruption, the angle of slant (?) may be generally comprises between 30 and 60 degrees and more preferably is 45 degrees or close to it. Naturally, the narrow interruption is created by masking it from dopant implantation when realizing the perimetral high voltage ring extension region.
