WebThe OTFOT method is based on charge pumping technique (CP) at low and high frequencies. We emphasize on the theoretical-based concept, giving a clear insight on the easy-use of the OTFOT ... WebAbstract—Charge pumping (CP) has proved itself to be one of the most utilitarian methods to quantify defects in MOS devices. In the presence of low-to-moderate gate …
WebAug 1, 1991 · An approach to the application of the charge pumping technique is proposed as a tool for the measurement of interface trap energy distributions in small area MOS transistors. The new approach is spectroscopic in nature, i.e., only one energy window is defined, and forced to move through the bandgap by changing the sample temperature. … WebMay 1, 2012 · This paper shows a successful transfer of the charge pumping (CP) method, which is extensively applied on silicon (Si) transistors, to Si carbide (SiC) lateral …
WebFeb 3, 2024 · Charge pumping is a two-step process in which the examiner alternately pulses the gate with a positive test voltage, then a negative one. (The transistor does not act as an on/off switch during this testing mode.) In traditional charge pumping, the alternating voltage pulses are applied at a single, set frequency. WebFig. 1. (a) Cross-sectional schematic and measurement conditions of CP for a recess-channel type transistor, and (b) schematic of the 200 000 cell array transistors connected in parallel. In (a), the gate pulses have a frequency of 0.1 MHz, a 50% duty cycle, and rising/falling slopes of 0.01 V/ns to ensure that the contribution of the CP current comes …
