Motorized Positioners

NIST-SS26-CHIPS-48

PLEASE NOTE THIS A SOURCES SOUGHT NOTICE ONLY

Title: Motorized positioners

BACKGROUND

Advanced semiconductor technology has led to continuous performance improvements in transistors. However, many iterations are needed to obtain optimal performance at millimeter wave frequencies and the yield and reproducibility is incredibly poor. Furthermore, US chip makers are ill-equipped with legacy measurement techniques and underperforming models. The National Institutes of Standards and Technology proposes a robust path to develop and verify high-frequency transistor models:  1) new on-wafer standards and calibration, 2) precision noise measurements for transistor quality assurance, 3) improved large signal characterizations, 4) optimal models tailored to a given technology, and 5) transistor model verification across frequency with key performance indicators.

NIST requires motorized linear translation stages for custom-built automated optical and RF wafer probing systems. These translation stages must have large travel ranges with 20 nm minimum movements for precision automated alignment of probing experiments.

 The required work provides two motorized positioners stages for wafer probing systems. These two motorized stages will be used to characterize high-frequency microelectronic devices under the CHIPS act program in the High Frequency Electronic laboratory, CTL, In Boulder CO.  

The minimum requirements are as follows:
