Abstract: A floating gate memory cell has a floating gate in which there are two floating gate layers. The top layer is etched to provide a contour in the top layer while leaving the lower layer unchanged. The control gate follows the contour of the floating gate to increase capacitance therebetween. The two layers of the floating gate can be polysilicon separated by a very thin etch stop layer. This etch stop layer is thick enough to provide an etch stop during a polysilicon etch but preferably thin enough to be electrically transparent. Electrons are able to easily move between the two layers. Thus the etch of the top layer does not extend into the lower layer but the first and second layer have the electrical effect for the purposes of a floating gate of being a continuous conductive layer.

Abstract: A CMOS-compatible FET has a reduced electron affinity polycrystalline or microcrystalline SiC gate that is electrically isolated (floating) or interconnected. The SiC material composition is selected to establish the barrier energy between the SiC gate and a gate insulator. In a memory application, such as a flash EEPROM, the SiC composition is selected to establish a lower barrier energy to reduce write and erase voltages and times or accommodate the particular data charge retention time needed for the particular application. In a light detector or imaging application, the SiC composition is selected to provide sensitivity to the desired wavelength of light. Unlike conventional photodetectors, light is absorbed in the floating gate, thereby ejecting previously stored electrons therefrom. Also unlike conventional photodetectors, the light detector according to the present invention is actually more sensitive to lower energy photons as the semiconductor bandgap is increased.

Abstract: A memory device (70) that uses a non-volatile storage element (38), such as nitride, has reduced read disturb, which is the problem of tending to increase the threshold voltage of a memory device (70) during a read. To reduce this effect, the memory device (70) uses a counterdoped channel (86) to lower the natural threshold voltage of the device (70). This counterdoping can even be of sufficient dosage to reverse the conductivity type of the channel (86) and causing a negative natural threshold voltage. This allows for a lower gate voltage during read to reduce the adverse effect of performing a read. An anti-punch through (ATP) region (74) below the channel (86) allows for the lightly doped or reversed conductivity type channel (86) to avoid short channel leakage. A halo implant (46) on the drain side (54, 53) assists in hot carrier injection (HCI) so that the HCI is effective even though the channel (86) is lightly doped or of reversed conductivity type.
