摘要:
A conveyor for a photo-processing apparatus having an exposing section and a developing section is disclosed. The conveyor conveys the photo-sensitive material from the exposing section to the developing section. A power source for conveying a photo-sensitive material in a vertical direction and a guide mechanism for guiding the photo-sensitive material in a lateral direction are installed in the conveyor. The lateral guidance of the photo-sensitive material by the guide mechanism is interlocked with the vertical conveyance by the power source to reduce the number of motors.

A technology for a semiconductor integrated circuitry allows each of the DRAM memory cells to be divided finely so as to be more highly integrated and operate faster. In a method of manufacturing such a semiconductor integrated circuit, at first, gate electrodes 7 are formed via a gate insulating film 6 on the main surface of a semiconductor substrate 1, and on side surfaces of each of the gate electrodes there is formed a first side wall spacer 14 composed of silicon nitride and a second side wall spacer 15 composed of silicon oxide. Then, in the selecting MISFET Qs in the DRAM memory cell area there are opened connecting holes 19 and 21 in a self-matching manner with respect to the first side wall spacers 14 and connecting portion is formed connecting a conductor 20 to a bit line BL. In addition, in the N channel MISFETs Qn1 and Qn2, and in the P channel MISFET Qp1 in areas other than the DRAM memory cell area, high density N-type semiconductor areas 16 and 16b are formed, as well as a high density P-type semiconductor area 17 is formed in a self-matching manner with respect to the second side wall spacers 15.
摘要:
A fabrication method of a semiconductor integrated circuit device comprises, in an SAC process or HARC process, subjecting a semiconductor substrate to plasma etching to make contact holes in an oxide film made of a silicon oxide film formed on the semiconductor substrate. For improving the ease-in-etching property of the silicon oxide film and selectivity to a nitride film, a residence time of an etching gas within a chamber is so set as to be in a range where selectivity to an insulating film made of silicon nitride is improved by using etching conditions of a low pressure and a large flow rate of the etching gas of C5H8/O2/Ar.

摘要:
In order to provide a method of treating a multilayer including metal and polysilicon for use in a conductor or a gate electrode of a semiconductor device with high accuracy at a high selectivity, the temperature of a sample is maintained at 100° C. or higher at the time of etching a metal film to increase the etch rate of the metal film. In order to suppress the etch rate of a polysilicon film and prevent side etching, an oxygen gas is added to a gas containing a halogen element. In order to suppress the etch rate of a silicon oxide film at the time of etching the polysilicon film, the etching is performed with etch parameters which are divided into those for the metal film and those for the polysilicon film. In the etching performed to the multilayer containing metal and polysilicon, by etching the metal film at a high temperature of 100° C. or higher, the etch rate of the metal film becomes high. Consequently, there is no partial etch residue of the metal film and a barrier film. By switching the parameters to those with which the polysilicon film can be etched at a high selectivity with respect to an oxide film at the time point of completion of etching to the barrier film, very accurate treatment can be realized.

摘要:
Various arrangements are proposed for coupling films to a leader. A hole is formed in one of the films and the leader to receive a tab which is formed on the other. These arrangements allow stable coupling of the films to the leader and easy uncoupling. They eliminate the use of splice tape.
