Abstract: A method for fabricating floating body memory cells (FBCs), and the resultant FBCs where gates favoring different conductivity type regions are used is described. In one embodiment, a p type back gate with a thicker insulation is used with a thinner insulated n type front gate. Processing, which compensates for misalignment, which allows the different oxide and gate materials to be fabricated is described.

Abstract: The present disclosure relates to the fabrication of spin transfer torque memory elements for non-volatile microelectronic memory devices. The spin transfer torque memory element may include a magnetic tunneling junction connected with specifically sized and/or shaped fixed magnetic layer that can be positioned in a specific location adjacent a free magnetic layer. The shaped fixed magnetic layer may concentrate current in the free magnetic layer, which may result in a reduction in the critical current needed to switch a bit cell in the spin transfer torque memory element.

Abstract: A phase change memory may be formed with an insulator made up of two different layers having significantly different thermal conductivities. Pores may be formed within the stack of insulating layers and the pores may be filled with heaters, chalcogenide layers, and electrodes in some embodiments. The use of the two different insulator layers enables embodiments where thermal losses may be reduced and an amorphous region may be maintained along the entire length of the phase change material layer.

Abstract: An improved dynamic memory cell using a semiconductor fin or body is described. Asymmetrical doping is used in the channel region, with more dopant under the back gate to improve retention without significantly increasing read voltage.

Abstract: Techniques associated with providing multiple gate insulator thickness for a semiconductor device are generally described. In one example, an apparatus includes a semiconductor fin having an impurity introduced to at least a first side of the fin, a first oxide having a first thickness coupled with the first side of the fin, and a second oxide having a second thickness coupled with a second side of the fin, the second thickness being different from the first thickness as a result of the impurity introduced to the first side of the fin.

Abstract: A hetero-BiMOS injection system comprises a MOSFET transistor formed on a substrate and a hetero-bipolar transistor formed within the substrate. The bipolar transistor can be used to inject charge carriers into a floating gate of the MOSFET transistor. This is done by operating the MOSFET transistor to form an inversion layer in its channel region and operating the bipolar transistor to drive minority charge carriers from the substrate into a floating gate of the MOSFET transistor. The substrate provides a silicon emitter and a silicon germanium containing base for the bipolar transistor. The inversion layer provides a silicon collector for the bipolar transistor.

Abstract: An integrated circuit (IC) has a number of memory cells, each of which has a diode structure coupled between a bitline and a wordline that are selected when programming that cell. A target memory cell of the IC is programmed while simultaneously floating a number of unselected bitlines and wordlines in the IC.

Abstract: A vertical channel flash memory cell with a silicon germanium layer in the channel region provides enhanced secondary electron injection when programming the device. The device includes a silicon substrate, a silicon germanium alloy layer epitaxially grown on the substrate, and a silicon layer epitaxially grown on the silicon germanium layer. A sidewall through the stacked structure is formed by etching thereby exposing edges of the silicon layer and the silicon germanium layer and a portion of the substrate. A floating gate is formed overlying the sidewall and insulated therefrom with a control gate overlying the floating gate and insulated therefrom. A source region is formed in the silicon layer and a drain region is formed in the substrate with a channel therebetween along the sidewall and including the silicon germanium layer. The silicon germanium layer is preferably compressively strained and can have a uniform mole fraction or a graded mole fraction.

Abstract: A field effect transistor such as a flash EEPROM device has channel region between a source region and a drain region with the channel region including a silicon germanium alloy layer epitaxially grown on a silicon substrate and a silicon cap layer epitaxially grown on the alloy layer. A floating gate is provided over and insulated from the channel region, and a control gate is provided over and insulated from the floating gate. The silicon germanium alloy layer and cap silicon layer provide for enhanced secondary impact ionization when injecting electrons from the channel region into the floating gate in programming the device. In a preferred embodiment the SiGe alloy layer is graded with the germanium mole fraction increasing from zero to some maximum value in the growth direction and with the germanium layer thickness being below a critical thickness for maintaining pseudomorphic strain.
