3D Chip Stacking, Hybridization, Indium Bumping

3D Chip Stacks are vertical laminations of one chip upon another chip with electrical connectivity. Often referred to as hybridization, pioneered for Infra-Red Focal Plane Arrays (IR FPAs), this allows for a read-out IC (ROIC), typically CMOS, to be bonded to a compound semiconductor 2-D detector or emitter array.

Arcnano specializes in IR FPAs, high power laser diodes, avalanche photo diodes or Si chip-on-chip. We perform backend processing including contact metallization, indium bumping, die singulation, hybridization and packaging.

Arcnano makes its own SiC vacuum chucks, in-house, and also for much of the industry.

Deposition, Photolithography, Etch Operations

Thin film deposition processes include Sputtering, Evaporation, CVD, LPCVD and ALD. Arcnano has over 100 sputtering targets and is expert at metallization, dielectrics, and magnetic thin films. Indium Bumping for 3D Chip stacking is accomplished in a dedicated Indium evaporation system.

Arcnano’s photo patterning consists of Suss MA/BA 6 with 1 um line widths as the minimum feature size. This capability is extended with Cannon and GCA steppers into the 250 nm feature size range.

Our standard etching processes include wet etching, Ion Milling, RIE, and DRIE.
