The SU-8 2000 Datasheet is a crucial resource for anyone involved in microfabrication, MEMS (Micro-Electro-Mechanical Systems), or microelectronics. It provides detailed specifications and guidelines for using SU-8 2000, a widely used epoxy-based negative photoresist. Understanding the information within the SU-8 2000 Datasheet is essential for achieving successful and reliable results in your microfabrication processes.
Demystifying the SU-8 2000 Datasheet What It Contains and How to Use It
The SU-8 2000 Datasheet is essentially the instruction manual for a specific type of SU-8 photoresist. It’s provided by the manufacturer (typically MicroChem Corp, now Kayaku Advanced Materials) and outlines everything from the chemical composition and physical properties of the material to recommended processing steps and safety information. Ignoring the datasheet is akin to building furniture without instructions it might work, but the chances of success are significantly reduced. The datasheet helps to control the results of your microfabrication process.
At its core, the datasheet provides critical parameters like:
- Viscosity: Vital for spin coating and determining film thickness.
- Solid Content: Affects the resist’s sensitivity to light and the final structure’s properties.
- Recommended Film Thickness vs. Spin Speed: A crucial table for controlling the dimensions of your microstructures.
These parameters are essential for a good microfabrication processes. You should pay attention to the storage of this chemical. For example:
| Parameter | Value |
|---|---|
| Storage Temperature | 4-27°C |
Beyond material properties, the SU-8 2000 Datasheet details the recommended processing steps. This includes information on:
- Soft Baking: Temperature and duration for solvent evaporation.
- Exposure: Wavelength and energy required for crosslinking.
- Post-Exposure Bake (PEB): Necessary for completing the crosslinking reaction.
- Development: Type of developer and development time.
Each of these steps is critical, and deviations from the recommended parameters can lead to poor adhesion, incomplete crosslinking, or unwanted pattern distortions. It also provides information on safety precautions, including handling and disposal guidelines, which are absolutely crucial for the safety of the user and the environment.
