Patent ID: 11667520

Abstract:
A manufacturing method for a micromechanical component. The method includes: providing an ASIC component including first front and rear sides, a strip conductor unit being provided at the first front side; providing a MEMS component including second front and rear sides, a micromechanical functional element situated in a cavity at the second front side; bonding the first front side onto the second front side; back-thinning the first rear side; forming vias starting from the back-thinned first rear side and from a redistribution unit on the first rear side, the vias electrically connecting the strip conductor unit to the redistribution unit; forming electrical contact elements on the redistribution unit; and back-thinning the second rear side. The back-thinning of the first and second rear side taking place so that a thickness of the stack made up of ASIC component and MEMS component is less than 300 micrometers.
