Method for the electrical insulation of a circuit function element on a semiconductor component

摘要

Method for the electrical insulation of a function element on a semiconductor component, wherein the function element is etched into a mesa (9) using a mask (8). A dielectric (10) is then applied surface-wide at least up to the height of the mesa (9). The more deeply disposed portions of this dielectric layer are covered with photoresist (11), and the photoresist (11) is caused to flow by tempering and, thus, is caused to level the surface. Finally, the photoresist (11) and the dielectric (10) are re-etched with the same etching rate until the mesa is uncovered.
