Description
The MRSI Automatic Die bonder is tool that can perform die-bonding automatically. It can handle various-sized chips, and uses pattern recognition to pick up and align parts. It can dispense and bond with epoxy or a eutectic station.
| Best for | High-speed pick and place of chips, including epoxy dispense. Ideal for large numbers of chips, as well as precision placement of very small chips |
| Limitations | Not recommended for one-offs, because it requires setup of image recognition for each part |
| Characteristics/FOM | N2, Epoxy |
| Caution with | moving parts |
| Machine Charges | 3/hour |

Process Matrix Details
Permitted
Been in the ALDSamples that have been in any of the ALD systems
, Pyrex SubstratesPyrex substrates can be a concern due to high sodium content, which contaminates CMOS frontend tools
, III-V SubstratesAny III-V substrates, e.g. GaAs, GaN, InP, and so on. Note though that many common III-V substrates will also carry the Au flag, but there are some GREEN III-V substrates.
, Germanium on surfaceSamples with germanium on the surface (typically grown films)
, Germanium buriedSamples with germanium buried below a different film
, PiecesWafer pieces may not be handled by the equipment, and are harder to thoroughly clean - preventing them from running in certain tools.
, Gold or RED color codeRED color code substrates. These are gold-contaminated or have been processed in gold contaminated tools. Gold and other metals can contaminate silicon devices (GREEN color code) and have to be separated.
, Any exposure to CMOS metalIf the sample had ever seen a CMOS metal (or a tool that accepts CMOS metal), then some frontend tools could be contaminated by this.
, CMOS metal on surfaceCMOS compatible metals exposed on the surface. These are Al,Ni,Pt,Ti,TiN. Other metals such as Au are *NOT* part of this.
, CMOS metal buriedCMOS compatible metals covered entirely by a different material. These are Al,Ni,Pt,Ti,TiN. Other metals such as Au are *NOT* part of this.
, Been in the STS DRIEThe DRIE etch leaves behind polymer residues on the sidewall ripples, which can be a contamination concern for some tools.
, Been in the SEMA sample viewed in the SEM must have used the appropriate chuck to avoid cross-contamination
, Been in the Concept1The Concep1 deposits dielectrics on GREEN wafers, however it also accepts metal and there can be cross-contamination for diffusion area
, Has PhotoresistSamples with photoresist cannot be exposed to high temperatures, which is typical in deposition tools. Outgassing can be a concern.
, Has PolyimidePolyimide is a very chemically resistant polymer, and can tolerate higher temperatures but cannot be exposed to typical PECVD deposition temperatures or diffusion furnaces. Outgassing can be a concern.
, Has Cured SU8Not fully cured SU8 residues can heavily contaminated plasma chambers or destroy other user's samples, but fully cured SU8 is permitted in certain tools.
, Coming from KOHAfter a KOH etch, the samples must receive a special clean because the K ions are highly contaminating to CMOS frontend tools
, Coming from CMPAfter a CMP, the samples must receive a special clean, because the slurry residues otherwise introduce contamination and particles.
Not Allowed
