The Laurell Spinner Laurell spinner is located in the ROBIN lab. A great variety of materials, that are not allowed to be spun in the clean room, can be spun here. This new tool replaces the old Solitec spinner and it is, as always, associated with the Solvent 94 bench. In order to reserve this tool users must reserve Solvent 94 bench. The main uses of this spinner are for soft lithography, polyimide processing and surface protection for dicing. There are just a few photoresist available for this tool, but users can bring private photoresist, or other spinnable materials provided they are approved.
- Aluminum foil on the lid helps with the cleaning. If users do not want to use it is fine, as long as the tool is throoughly claned after use
- When spinning a thin phtoresist we recommend to remove the aluminum foil or puddles formed during spinning will empty when opening the lid and ruin the sample
- Users spinning Polyimide must be extra careful and make sure spinner is clean after use. Polyimide dries up and forms flakes that will deposit ruin the freshly spun film.
- Can spin 100 mm, 150 mm, glass slides and pieces
- wafer aligner tool
Chemicals Spinned in this Bench
- Photoresist for dicing protection
- This tool is exhausted
- There are different chucks for wafers (100 mm and 150 mm use same chuck), glass slides and pieces
- The spinner door must be closed and vacuum must be on to operate the tool
- Users MUST clean the bowl and lid throroughly after each use
- Wafer must cover the chuck used completely. If not photoresist will be aspirated down the vacuum hole and eventually clog it
- Back of the wafer MUST be clean or vacuum will not be good enough for the spinner to operate
- Square samples will not spin a uniform film, material will accumulate on the corners, consider this and surface tension of the fluid when choosing the substrate
When spinning a material not listed above, contact tool engineer.
There are several processes for this tool supported by the LNF, which are described in more detail on the Processes page.
In addition to these, this tool has a number of user-created recipes for etching a wide variety of materials. Some of these recipes are documented on Laurell Spinner user processes. If you are curious if your material can be processed in this tool, please contact the tool engineers via the helpdesk ticket system.
