摘要:
A disk array apparatus has a plurality of disks constituting a mounted RAID group and controls access from an upper-level device to each of the disks. The disk array apparatus also has a performance information collector for collecting a piece of performance-related information of each of the disks, and a suspected disk detector for comparing the pieces of information collected for the disks by the performance information collector among disks constituting a single one of the RAID group and detecting a suspected disk suspected of being abnormal in performance based on a result of the comparison.

Provided is a substrate processing apparatus wherein, even if a trouble occurs, it is bound to continue a process for the substrate without stopping the substrate processing apparatus entirely. The substrate processing apparatus according to the present disclosure includes first and second substrate conveying devices configured to convey wafers, and first and second processing blocks provided on the right and left sides of the substrate conveying device and having processing unit arrays each configured to perform the same process. Processing unit arrays on one side and processing unit arrays on the other side are respectively connected to a processing liquid supply system commonly provided with them. And, when any one of substrate conveying devices, processing liquid supply systems has a problem, the process for the wafer can be performed in the processing unit array to which the substrate conveying device and the processing liquid supply system under normal operation belong.
摘要:
A delay circuit (100) includes capacitor elements constituted of nMOS transistors (141, 142) between an input inverter circuit (110) and an output inverter circuit (120). The input inverter circuit (110) includes a pMOS transistor (PM1) and an nMOS transistor (NM1) that are directly connected between a power source potential (VDD) and a ground potential (VSS) through a resistor (R1). Between a signal line (130) and the gate of the nMOS transistor (141), and between the signal line (130) and the gate of the nMOS transistor (142), pMOS transistors (151, 152) are provided, respectively. In this structure, in the case where an input signal is changed from L to H, the PVT sensitivity of a delay circuit is automatically alleviated. As a result, the PVT sensitivity is automatically alleviated.

The semiconductor device includes a reference voltage generator circuit and a circuit different from the reference voltage generator circuit. A semiconductor element of the reference voltage generator circuit has a channel region where a substrate impurity concentration is substantially uniform at least in the vicinity of a drain region. A semiconductor element of the circuit different from the reference voltage generator circuit has a channel region where a substrate impurity concentration is higher than in other part of the region at least in the drain region.
