Adding Atoms to
Select Areas

선택적 증착

복잡한 패터닝 설계, 더 높은 종횡비, 더 작은 비아채널, 더 취약한 형상, 증가하는 패턴 붕괴의 위험으로 인해 벌크 재료 엔지니어링에서 선택적 공정으로 빠르게 전환되고 있습니다.

Selective processes use co-designed chemical and materials interactions to enable delicate and precise deposition and removal of target materials. Selective deposition and epitaxy is additive manufacturing at an atomic scale, putting atoms only where they are needed. Selective etch is subtractive manufacturing at an atomic scale, removing only unwanted atoms—even those beyond the line of sight—and leaving the rest in place. Selective deposition, epitaxy and etch technologies can be used to create and shape tiny patterns; fabricate novel structures; and overcome technology roadblocks such as the pattern collapse associated with wet processes, edge-placement errors in patterning, and 2D scaling issues associated with transistor contact and interconnect resistance.

Applied leads the industry in selective deposition and selective epitaxy processes.  The Endura Copper Barrier Seed IMS™ replaces standard high-resistance via interfaces with a low-resistance selective ALD barrier to enable interconnect metallization for 3nm and beyond.  Similarly, the Endura Volta Selective W CVD system replaces conventional metal and dielectric liners and barriers with selective Tungsten deposition to lower contact resistivity and reduce the bottleneck of 2D scaling.  The Endura Volta CVD Cobalt system provides a robust seed layer for copper lines and selective Cobalt cap to strengthen adhesion at the copper-dielectric interface.  Finally, the Centura Prime Epi system plays a critical role in strain engineering Si-Ge channel performance found in FinFET and GAA transistors.
