semiconductor equipment temperature control thin film platinum resistor

 

Is it difficult to meet the temperature control standard of ± 0.1 ℃ in semiconductor wafer process? How does TCR3750 thin film platinum resistor break through?


In the scenarios of temperature control of lithography machine lenses (± 0.1 ℃) and temperature uniformity of etching machine chambers (± 0.5 ℃), semiconductor manufacturing equipment uses temperature controlled thin film platinum resistors with "nano level stability+vacuum compatible packaging" to solve the problem of drift above ± 1 ℃ caused by long-term operation of traditional sensors

H2: Two major technical bottlenecks in temperature control of semiconductor equipment

 


H3: Long term drift: Traditional sensors experience a resistance drift of ± 2% after 1000 hours in vacuum (10 ⁻⁶ Pa) and high temperature (200 ℃) environments, resulting in a 5% decrease in wafer yield;


H3: Poor vacuum compatibility: Organic packaging materials release gases, polluting lithography machine lenses, and maintenance costs exceed one million yuan per time.

H2: Advantages of TCR3750 Thin Film Platinum Resistors in Semiconductor Scenarios

 


Our semiconductor manufacturing equipment temperature controlled thin film platinum resistors use metal thin film technology (non organic packaging), with a resistance drift of<± 0.1% after 1000 hours in a vacuum environment. Combined with laser tuning technology, the accuracy reaches ± 0.05 ℃ (the top level in the industry).


H3: Anti electromagnetic interference: The electromagnetic field strength of wafer manufacturing equipment (such as plasma etching machines) is greater than 100V/m, the sensor has passed EMC Class B certification, and the signal has zero interference;

 


After being used in a certain 12 inch wafer fab, the yield loss caused by temperature drift of the lithography machine decreased from 3% to 0.2%, with an annual efficiency increase of over 20 million yuan. This is precisely the value of temperature controlled thin film platinum resistors in semiconductor manufacturing equipment.
