Auxiliary input for analog-to-digital converter input charge
Input stages for an analog to digital converter wherein charge for charging parasitic capacitances in the input stage, and particularly in the input switch is sourced from a node which means that it does not have to pass through the input RC filter.

The article is moved by a predetermined increment relative to the reference position to position the article in a target position in response to determining that the sensor is in the reference position. |

Substrate processing method and substrate processing apparatus
A technique to prevent reduction in throughput of a substrate processing apparatus. On the occurrence of an event disabling execution of a recipe by a processing unit, a different recipe executed by this processing unit may be used depending on the type of event having occurred. The type of event to occur and a substitute recipe that can take the place of a recipe being executed are associated in advance. On the occurrence of abnormality, it is determined whether or not a recipe being executed can be substituted by a different recipe. If the recipe can be substituted, it is determined whether or not the substitute recipe is contained in an unfinished job. If these conditions are satisfied, a substrate processing schedule is changed to execute the substitute recipe in this processing unit. If these conditions are not satisfied, substrate process in this processing unit is stopped. |
