Abstract: The semiconductor device includes a substrate (5,6,10) with an (n-) type front region and a back region (5) forming a first main connection. An n type well (40') is formed in a first region (10). A p type well (70) is formed in the first region. The second well forms a p type channel region (K) in a portion of the first well. A (n+) type third well is formed in the first region. The third well forms a second main connection in a common portion of the first and second well. A third main connection is provided over the channel region (K).

Abstract: The invention relates to a method for generating a switching or control signal after a period that can be predetermined. At the beginning of timing a voltage (U) is applied to an inductivity (L) that serves as a time function element. If the current (I) passing through the inductivity (L) exceeds a threshold value that can be predetermined, a current threshold detector (ID) emits the switching or control signal. In an electronic ignition system for internal combustion engines the ignition coil (L, PW, SW) does not only generate an ignition voltage but represents also a time function element for a timer system (UD1, UD2, LS) that cuts off the current (I) passing through the primary winding (PW) of the ignition coil (L) after a period that can be predetermined. The current (I) is cut off on the basis of a differential function dI/dt that is chosen so that the ignition voltage induced at the ignition coil (L) does not suffice to generate an ignition spark on the ignition plugs.
