Title: Semiconductor integrated circuit provided with esd protection circuit
Inventor: IKEDA HIROYUKI
IPC: H01L27/092
Filed: 2007-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a chip-occupying area in an ESD protection circuit.  <P>SOLUTION: A semiconductor integrated circuit includes an ESD protection circuit ESD_HV, a power-supply voltage feed terminal HI_Pad, a ground-voltage feed terminal LOW_Pad, and an enable external terminal EN_Pad. The ESD protection circuit includes an inverter INV, which responds to a voltage of the enable external terminal, and a clamping element Qn1_HV conductive between the power-supply voltage feed terminal HI_Pad and the ground-voltage feed terminal LOW_Pad, in response to an output signal of the INV. In the non-active state, prior to the semiconductor integrated circuit is mounted to a circuit board of application system equipment, the enable external terminal EN_Pad is substantially made to go into a floating state (intermediate voltage). When an ESD voltage is produced between the power-supply voltage feed terminal HI_Pad and the ground-voltage feed terminal LOW_Pad in the non-active state, the clamping element Qn1_HV becomes conductive so as to absorb the ESD voltage. This eliminates conventional time-constant circuit, and consequently, chip-occupying area in the ESD protecting circuit can be reduced.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To effectively manufacture a hot-rolled steel material having a good surface property by suppressing the generation of surface defects due to Ni concentration or the like.  <P>SOLUTION: In the manufacturing method of a hot-rolled steel sheet, descaling is performed by high-pressure water jetted at a heating furnace outlet side, roughing mill inlet side and finishing mill row inlet side by high-pressure water jetting, and descaling (a<SB>X</SB>) is further performed at least at one spot between the roughing mill row and finishing mill row by high-pressure water jetting.
