Abstract
A method for manufacturing a semiconductor structure includes: forming an interconnect level structure having a first device region, a first side region aside the first device region, a second device region and a second side region aside the second device region; forming a dielectric layer over the interconnect structure, the dielectric layer including a first dielectric portion, a second dielectric portion, a first patterned portion and a second patterned portion that are respectively formed over the first device region, the second device region, the first side region, and the second side region, the first patterned portion and the second patterned portion being formed with different patterns; performing a planarization process on the dielectric layer; forming first recesses and second recesses respectively in the planarized first dielectric portion and the planarized second dielectric portion; and forming contact portion respectively in the first recesses and the second recesses.
