Hotplates

Feedback to this section: click here

Hotplate: 90-110C

Hotplate: 90-110C is used for baking of 2" - 6" wafers. Do not exceed 120°C.

The user manual, and contact information can be found in LabManager: Hotplate: 90-110C

Hotplate 1 (SU8) and Hotplate 2 (SU8)

We have two dedicated SU-8 hotplates in C-1.

Users can control the ramp-time, the baking temperature, and the baking time. In order to avoid thermal curing of SU-8 residues on the hotplates, they are temperature limited to 110°C.

The user manual, and contact information can be found in LabManager: Hotplate 1 (SU8) Hotplate 2 (SU8)

Ovens

Oven 90C

The oven is mostly used for baking of several wafers at a time at 90 °C as a soft baking step after a spin coating of photoresist. For 1.5µm resist the baking time is 30 min. For most of the other resist thicknesses it is also 30 min.

The user manual, and contact information can be found in LabManager: Oven 90C

Oven: 110C - 250C

Variable temperature convection oven mostly used for baking of wafers as a hard baking step after development of photoresist.

The set-point can be varied, but should always be returned to 110°C after use.

The user manual, and contact information can be found in LabManager: Oven: 110C - 250C

Oven 250C for pretreatment
