[labnetwork] HF compatible container for single wafer dipping

[Paul Maciel]

Hi Chito,

Idonus SARL has fabricated similar basins, see the brochure attached.

Drop me an email if your interested and I can generate a quotation.

Regards and have a good day,

Dear,

Before I spend a whole lot of time fabricating a container, I do have a plastic welder, I want to see if anyone knows of a company that sells narrow containers with a flat stable bottom for single wafer dipping of wafers.

We have a fairly standard wet bench for processing wafers by RCA/HF/solvents. However this means we need to have at least 10L of chemicals to cover 25 4" wafers in a standard carrier if we want to use the bench baths. For single wafers we have flat containers to use less HF, but students have a lot of issues with getting wafers in/out with teflon tweezers and with the extra PPE gloves. We do have holders for single wafers, but with the amount of processing we are currently doing 10L of 5% HF or 6:1 BOE is just a waste for the odd wafer and leaving HF in the bath does lead to it reducing in volume.

Therefore, I am looking for a container that is 1"x5"x8" (WxDxH) and has a large base as it will be top heavy being so narrow. This will allow wafer dipping with the holders and removes handling issues.

Regards,

Chito Kendrick
