Sealing method for electronic devices formed on a common semiconductor substrate and corresponding circuit structure

A method for sealing electronic devices formed on a semiconductor substrate comprising:

• forming at least one first conductive layer on a first portion of the semiconductor substrate;
• forming a second conductive layer on a second portion of the semiconductor substrate;
• forming a first plurality of regions in the at least one first conductive layer for defining first electronic devices on the first portion of the semiconductor substrate;
• forming a first sealing layer on the first plurality of regions for sealing the first electronic devices, and on the second conductive layer;
• forming a second plurality of regions in the second conductive layer for defining second electronic devices on the second portion of the semiconductor substrate and so that the second electronic devices have at least portions of the first sealing layer thereon;
• and
• forming a second sealing layer on the second plurality of regions for sealing the second electronic devices having at least portions of the first sealing layer thereon, and on the first sealing layer sealing the first electronic devices.
