Spin Track 1 + 2

Spin Track 1 + 2 in C-1

Feedback to this section: click here

Spin Track 1 + 2 is an SVG 88 series track system from Rite Track. Each track consists of a HMDS priming module, a spin coating module, and a baking module. In fact, the only difference between the two tracks is the resist used in the spin coating module. Spin Track 1 + 2 is capable of handling 150 mm wafers, as well as 100 mm wafers, but is currently set up for 100 mm wafer processing.

The Spin Track 1 + 2 is controlled using the Recipe Manager software via the touchscreen on the arm attached to the lefthand end of the track. Recipes for the individual modules are developed by Danchip and combined into flows. The user selects a flow (specific to track 1 or 2), and the appropriate recipes will be downloaded and executed on the appropriate track. The other track runs an empty process (no wafers needed), and can unfortunately not be used by a second user while the first user is processing.

The user manual, user APV, and contact information can be found in LabManager

KS Spinner

The KS spinner is placed in C-1

Feedback to this section: click here

At Danchip we have RC8-THP system which is one of the SUSS MicroTech spinners.

The main purpose of this equipment is experimental spinning the different resist.The spinner has one resist line, AZ5214E, for automatic dispense. All other resist dispenses manually from syringe or disposable pipettes. All SU8 spinning are done on this machine.

The machine can be also used for spinning on the "difficult" surfaces like the substrates with holes, backside structures and unusual shapes.
