| Brand | ConductScience |
The Photolithography Hot Plate provides precise thermal processing capabilities for photoresist baking and microfluidic device fabrication. This laboratory-grade heating platform delivers controlled temperature environments essential for photolithography workflows, including soft baking, hard baking, and thermal processing of polymer substrates.
The 300 × 300 mm heating surface accommodates standard wafer sizes and substrate dimensions commonly used in microfabrication processes. The compact 100 mm profile integrates efficiently into cleanroom and laboratory environments where space optimization is critical. Temperature uniformity across the heating surface ensures consistent processing results for photoresist applications and thermal curing processes.
How It Works
The hot plate operates through resistive heating elements embedded within the platform structure. Electrical current passes through high-resistance heating elements, converting electrical energy to thermal energy that is conducted uniformly across the heating surface. Temperature control is achieved through feedback systems that monitor surface temperature and adjust power input to maintain setpoint conditions.
Heat transfer occurs primarily through conduction from the heated surface to the substrate in direct contact. The thermal mass of the heating platform provides temperature stability and minimizes fluctuations during processing. Uniform heat distribution across the 300 × 300 mm surface ensures consistent processing conditions for photoresist baking and substrate thermal treatment applications.

Practical Tips
Perform temperature mapping using multiple measurement points across the heating surface before establishing process protocols.
Why: Temperature uniformity verification ensures consistent processing results across all substrate positions.
Clean the heating surface regularly with appropriate solvents to prevent buildup of photoresist residues or other process materials.
Why: Surface contamination can affect heat transfer efficiency and compromise thermal uniformity.
Allow adequate warm-up time before processing to achieve thermal equilibrium across the entire heating surface.
Why: Thermal equilibrium ensures stable processing conditions and prevents temperature gradients during substrate placement.
Implement proper ventilation when processing materials that release vapors or solvents during thermal treatment.
Why: Adequate ventilation prevents accumulation of potentially hazardous vapors in the work environment.
Document temperature profiles and timing parameters for each process to ensure reproducible results.
