  • Publication number: 20150087127
    Abstract: An integrated circuit contains a transistor with a stress enhancement region on the source side only. In a DeMOS transistor, forming the stress enhancement region on the source side only and not forming a stress enhancement region in the drain extension increases the resistance of the drain extension region enabling formation of a DeMOS transistor with reduced area. In a MOS transistor, by forming the stress enhancement region on the source side only and eliminating the stress enhancement region from the drain side, transistor leakage is reduced and CHC reliability improved.

  • Publication number: 20140171442
    Abstract: Disclosed are alicyclic[c]benzopyrone derivatives and use thereof. The alicyclic[c]benzopyrone derivatives are compounds represented by formula I or their salts. The present compounds not only significantly improve high activity induced by MK-801, but also effectively improve clambering symptom induced by Apomorphine and do not cause EPS within effective dose. These in vitro targets and in vivo pharmacological models are closely related to diseases of the nervous system caused by dopamine dysfunction, especially schizophrenia. Therefore the present compounds can be used for the treatment of central nervous system diseases, especially schizophrenia. ED50 is lower and effect is stronger in two animal models i.e. high activity induced by MK-801 and clambering symptom induced by Apomorphine, while ED50 is higher and therapeutic index is greater in animal models of catalepsy.

  • Patent number: 8748256
    Abstract: A method for forming an integrated circuit (IC) including a silicide block poly resistor (SIBLK poly resistor) includes forming a dielectric isolation region in a top semiconductor surface of a substrate. A polysilicon layer is formed including patterned resistor polysilicon on the dielectric isolation region and gate polysilicon on the top semiconductor surface. Implanting is performed using a first shared metal-oxide-semiconductor (MOS)/resistor polysilicon implant level for simultaneously implanting the patterned resistor polysilicon and gate polysilicon of a MOS transistor with at least a first dopant. Implanting is then performed using a second shared MOS/resistor polysilicon implant level for simultaneously implanting the patterned resistor polysilicon, gate polysilicon and source and drain regions of the MOS transistor with at least a second dopant. A metal silicide is formed on a first and second portion of a top surface of the patterned resistor polysilicon to form the SIBLK poly resistor.

  • Patent number: 8125035
    Abstract: Ultra high temperature (UHT) anneals above 1200 C for less than 100 milliseconds for PMOS transistors reduce end of range dislocations, but are incompatible with stress memorization technique (SMT) layers used to enhance NMOS on-state current. This invention reverses the conventional order of forming the NMOS first by forming PSD using carbon co-implants and UHT annealing them before implanting the NSD and depositing the SMT layer. End of range dislocation densities in the PSD space charge region below 100 cm?2 are achieved. Tensile stress in the PMOS from the SMT layer is significantly reduced. The PLDD may also be UHT annealed to reduce end of range dislocations close to the PMOS channel.

  • Patent number: 8101476
    Abstract: A method for forming a tensile SiN stress layer for stress memorization enhancement of NMOS transistors with a high Si—H/N—H bond ratio that does not degrade PMOS transistors. A CMOS integrated circuit is processed through a NMOS source and drain implant but not through NMOS source and drain anneal. A SiN dielectric layer is deposited such that an area ratio of a Si—H peak to a N—H peak in a FTIR spectrum is greater than 7 and a tensile stress of the SiN dielectric is greater than 150 MPa. The CMOS integrated circuit is annealed after deposition of the SiN dielectric layer and the SiN dielectric layer is removed from at least a part of the integrated circuit.
