A Simple Technique to Measure Generation Lifetime in Partially Depleted SOI MOSFET’s
نویسندگان
چکیده
This brief presents a new, simple method of measuring the generation lifetime in silicon-on-insulator (SOI )MOSFET’s. Lifetime is extracted from the transient characteristics of MOSFET subthreshold current. Using this technique, generation lifetime was mapped across finished Separation by IMplantation of OXygen (SIMOX) wafers and Bonded and Etchedback SOI (BESOI) wafers. BESOI material evaluated in this study had about seven times longer effective generation lifetime than SIMOX material and both the SIMOX and the BESOI are shown to have a lifetime variation of 10% across four inch wafers.

Measurement of carrier generation lifetime in SOI devices
This paper presents a new, simple method of measuring the generation lifetime in SOI (silicon-on-insulator) MOSFETS. Lifetime is extracted from the transient characteristics of MOSFET subthreshold current. Using this technique, generation lifetime was mapped across ®nished SIMOX (separation by implantated oxygen) wafers, BESOI (bonded and etchedback SOI) wafers, and UNIBOND wafers. BESOI materi...
متن کاملOutput-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...

SOI means Silicon on Insulator. This type of transistors has Silicon-Insulator-Silicon substrate which is different from conventional MOSFET structure where metal layer is used on the top of Insulator [1, . Now a days, the width of the oxide of a MOSFET is reduced from 300nm to 1.2nm and even less with scaling in technology. If it is further reduced, the leakage problems (majorly Sub-threshold ...

Silicon On Insulator (SOI) can leverage a lot of new advantages for circuit designers compared to conventional bulk technology. In particular, the improved S-factor and reduced junction capacitance make it very appealing for next generation low power, high performance DRAM systems. However, the benefits of the SOI technology do not come entirely for free. In this project, we characterized the k...
