Hotplates

Hotplate: 90-110C

Hotplate: 90-110C is used for baking of 2" - 6" wafers.

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

SU8 hotplates

Hotplate 1 (SU8) and Hotplate 2 (SU8) situated in C-1

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

Users can control the ramp-time, the baking temperature, and the baking time.

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

Fumehood hotplates

Variable temperature hotplate mostly used for baking of single wafers as a soft baking step after a spin coating of photoresist.

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: 120C - 250C

The user manual, and contact information can be found in LabManager: Oven: 120C - 250C

Oven 250C for pretreatment
