Abstract
A method for sealing electronic devices formed on a semiconductor substrate includes forming a plurality of first electronic devices adjacent a first portion of the semiconductor substrate, with each first electronic device including a first region comprising at least one first conductive layer projecting from the semiconductor substrate. A first sealing layer is formed adjacent the first regions for sealing the plurality of first electronic devices. A protective layer is formed adjacent the first sealing layer. The protective layer is etched to form protective spacers adjacent sidewalls of the first regions. The method further includes forming a plurality of second electronic devices adjacent a second portion of the semiconductor substrate, with each second electronic device including a second region comprising a second conductive layer projecting from the semiconductor substrate. A second sealing layer is formed adjacent the second regions for sealing the plurality of second electronic devices, and adjacent the first sealing layer for sealing the plurality of first electronic devices.
