摘要： A noise monitoring apparatus includes a row selection circuit, a direct current (DC) cancellation circuit and an amplifier circuit. The row selection circuit selects a row of a DUT array to be a selected row during a readout period, wherein the selected row comprises a plurality of selected DUTs. The DC cancellation circuit is coupled to unselected DUTs of the DUT array during the readout period, generates a DC current signal based on bias current signals from a group of unselected DUTs and subtract the DC current signal from a first noise signal of the selected DUT to generate a second noise signal. The amplifier circuit is coupled to the plurality of selected DUTs of the selected row during the readout period, and amplifies the second noise signal from each of the selected DUTs to generate an output signal.

摘要： A semiconductor device comprises a source/drain diffusion area, and a first doped region. The source/drain diffusion area is defined between a first isolation structure and a second isolation structure. The source/drain diffusion area includes a source region, a drain region, and a device channel. The device channel is between the source region and the drain region. The first doped region is disposed along a first junction between the device channel and the first isolation structure in a direction from the source region to the drain region. The first doped region is separated from at least one of the source region and the drain region, and has a dopant concentration higher than that of the device channel. The semiconductor device of the present disclosure has low random telegraph signal noise and fewer defects.

The first doped region is located within a projected area of the gate onto the source/drain diffusion area, the first isolation structure and the second isolation structure. A length of the first doped region is shorter than a length of the gate in a direction from the source region to the drain region.
