【Southport】3D Stress Inspection & Analysis System for WBG Materials

JadeSA-WBG, Non-contact Whole Wafer / MicroArea 3D Stress Inspection and Analysis System for WBG Materials

  • Effectively reflect the intrinsic property of WBG materials ‒ stress distribution on surface and in depth
  • Suitable for monitor the stress distribution and polytype uniformity of SiC substrate, homogeneous and heterogeneous epi wafer, and device process review

 

【Features】

  • Advanced 3D Raman inspection technology
  • Effectively reflect the intrinsic property of WBG materials ‒ stress distribution on surface and in depth
  • Capable of providing the percentage of unexpected polytype in the wafer
  • Capable of performing whole wafer scan at specific depth with stress mapping
  • Capable of performing MicroArea 3D stress mapping
  • Capable of performing 3D polytype analysis
  • Suitable for monitor the stress distribution and polytype uniformity of SiC substrate, homogeneous and heterogeneous epi wafer, and device process review
  • Applied to 2”, 4”, 6”, 8” substrates

 

【Advantages】

  • Suitable for inspect and identify unexpected polytype in wafers
  • Suitable for analyzing the differences of stress distribution between substrates from the same ingot
  • Suitable for analyzing the stress distribution of substrate and epi layer, and the correlation with major crystal defects
  • Suitable for epi manufacture to conduct IQC on incoming substrate
  • Detailed 3D MicroArea stress mapping facilitates defects and process analysis
  • Suitable for analyzing the effects of process and temperature on the change of defects and crystal morphology
 

 

【Benefits】

  • Help improve the ingot growth process by examining substrates from the same ingot and ingots from different batches or parameters
  • Help improve the SiC CMP process by examining substrates from the same ingot
  • Improve epi process performance and achieve heterogeneous integration process optimization
  • Help establish the causal relationship from material-end to the device-end, further build a deeper know-how and know-why, improve yield, output, performance and component reliability, and effectively reduce the overall cost
