  • Patent number: 7148116
    Abstract: A semiconductor device with a load resistor is manufactured such that a contact is formed at both ends of the load resistor, and at least one contact is formed between the contacts, in order to prevent impurities from being generated within each contact while the contacts are being generated by etching an insulation layer phenomena of electric charge build up from occurring when an etching process fabricates an insulation layer to generate the contact in a long load resistor located under the insulation layer and insulated electrically and physically.
    Type: Grant

  • Patent number: 5981324
    Abstract: Methods of forming integrated circuits having memory cell arrays therein and peripheral circuits therein include the steps of selectively forming more lightly doped source and drain regions for transistors in the memory cell arrays. These more lightly doped source and drain regions are designed to have fewer crystalline defects therein caused by ion implantation, so that storage capacitors coupled thereto have improved refresh characteristics. Preferred methods include the steps of forming a first well region of first conductivity type (e.g., P-type) in a memory cell portion of a semiconductor substrate and a second well region of first conductivity type in a peripheral circuit portion of the semiconductor substrate extending adjacent the memory cell portion. First and second insulated gate electrodes are then formed on the first and second well regions, respectively, using conventional techniques.
