| 20100258868 | INTEGRATED CIRCUIT SYSTEM WITH A FLOATING DIELECTRIC REGION AND METHOD OF MANUFACTURE THEREOF - A method of manufacture of an integrated circuit system includes: providing a second layer between a first layer and a third layer; forming an active device over the third layer; forming the third layer to form an island region underneath the active device; forming the second layer to form a floating second layer with an undercut beneath the island region; and depositing a fourth layer around the island region and the floating second layer. | 10-14-2010 |
| 20100304556 | INTEGRATED CIRCUIT SYSTEM WITH VERTICAL CONTROL GATE AND METHOD OF MANUFACTURE THEREOF - A method of manufacture of an integrated circuit system includes: providing a mesa over a substrate; forming a trench in the substrate adjacent the mesa; forming a second gate and a charge storage material along a trench sidewall; and forming a first gate from the mesa. | 12-02-2010 |
| 20110044115 | Non-volatile memory using pyramidal nanocrystals as electron storage elements - A non-volatile memory device includes a floating gate with pyramidal-shaped silicon nanocrystals as electron storage elements. Electrons tunnel from the pyramidal-shaped silicon nanocrystals through a gate oxide layer to a control gate of the non-volatile memory device. The pyramidal shape of each silicon nanocrystal concentrates an electrical field at its peak to facilitate electron tunneling. This allows an erase process to occur at a lower tunneling voltage and shorter tunneling time than that of prior art devices. | 02-24-2011 |
| 20110115009 | CONTROL GATE - A method for forming a semiconductor device is disclosed. The method includes providing a substrate prepared with a second gate structure. An inter-gate dielectric is formed on the substrate and over the second gate. A first gate is also formed. The first gate is adjacent to and separated from the second gate by the inter-gate dielectric. The substrate is patterned to form a split gate structure with the first and second adjacent gates. The split gate structure is provided with an e-field equalizer adjacent to the first gate. The e-field equalizer improves uniformity of e-field across the first gate during operation. | 05-19-2011 |
| 20110156121 | MEMORY CELL WITH IMPROVED RETENTION - A method for forming a device is presented. A substrate prepared with a feature having first and second adjacent surfaces is provided. A device layer is formed on the first and second adjacent surfaces of the feature. A first portion of the device layer over the first adjacent surface includes nano-crystals, whereas a second portion of the device layer over the second adjacent surface is devoid of nano-crystals. | 06-30-2011 |
| 20120007180 | FinFET with novel body contact for multiple Vt applications - FinFET devices are formed with body contact structures enabling the fabrication of such devices having different gate threshold voltages (Vt). A body contact layer is formed to contact the gate electrode (contact) enabling a forward body bias and a reduction in Vt. Two example methods of fabrication (and resulting structures) are provided. In one method, the gate electrode (silicon-based) and body contact layer (silicon) are connected by growing epitaxy which merges the two structures forming electrical contact. In another method, a via is formed that intersects with the gate electrode (suitable conductive material) and body contact layer and is filled with conductive material to electrically connect the two structures. As a result, various FinFETs with different Vt can be fabricated for different applications. | 01-12-2012 |
| 20120007185 | Novel method to tune narrow width effect with raised S/D structure - A method (and semiconductor device) of fabricating a semiconductor device adjusts gate threshold (Vt) of a field effect transistor (FET) with raised source/drain (S/D) regions. A halo region is formed in a two-step process that includes implanting dopants using conventional implantation techniques and implanting dopants at a specific twist angle. The dopant concentration in the halo region near the active edge of the raised S/D regions is higher and extends deeper than the dopant concentration within the interior region of the raised S/D regions. As a result, Vt near the active edge region is adjusted and different from the Vt at the active center regions, thereby achieving same or similar Vt for a FET with different width. | 01-12-2012 |
