    摘要: A method for regenerating a used wafer or substrate by removing a functional coating film formed on the used wafer or substrate, comprising the steps of:(a) a step for sorting the used wafer or substrate according to the quality, structure or thickness of the functional coating film;(b) a step for removing the functional coating film, while in a state of holding the used wafer or substrate, (i) by lapping the objective face of the used wafer or substrate with a hard metal-bonded whetstone while applying an electrochemical in-process dressing, (ii) by polishing the objective face while dropping a fine-particle polishing slurry between a polishing plate provided with a pad and the functional coating film, or (iii) by electrolyzing the functional coating film on the objective face placed opposite to an electrode face in an electrolyte solution at a predetermined voltage;(c) a step for mechanically removing the functional coating film adhered to the end face at an adequate stage; and(d) a step for washing and drying the used wafer or substrate after removal of the functional coating film.

    摘要: In order to improve the performance of a semiconductor integrated circuit device wherein a capacitor provided between storage nodes of an SRAM and a device having an analog capacitor are formed on a single substrate, a plug is formed in a silicon oxide film on a pair of n channel type MISFETs in a memory cell forming area, and a local wiring LIc for connecting respective gate electrodes and drains of the pair of n channel type MISFETs is formed over the silicon oxide film and the plug. Thereafter, a capacitive insulating film and an upper electrode are further formed over the local wiring LIc. According to the same process step as the local wiring, capacitive insulating film and upper electrode formed in the memory cell forming area, a local wiring LIc, a capacitive insulating film and an upper electrode are formed over a silicon oxide film in an analog capacitor forming area and a plug in the silicon oxide film.

    摘要: A technique for forming a plurality of MISFETs having desired threshold voltages on a SOI substrate is provided. Each gate electrodes of pMIS and nMIS is made of a metal film having a work function approximate to that of a channel region of the pMIS, such as a molybdenum or ruthenium film, and a rise of the threshold voltage due to the metal film is reduced by inducing a positive fixed charge in a BOX layer. Thereby, the pMIS and nMIS having the desired threshold voltages can be formed on the SOI substrate.
