An electric grill with a cooking surface for cooking food, which cooking surface has at least two adjacent heating zones is disclosed. Each heating zone of the grill is assigned a first electrical heating element 8 for heating the cooking surface in this heating zone, H.sub.1, H.sub.2. A second heating element 9 is arranged in a subset of the heating zones (H.sub.1) for increasing the heating power in this heating zone (H.sub.1) with a power input that at least matches that of a first heating element 8 of another heating zone (H.sub.2). The grill 1 has a heating element switchover feature, such that, when a second heating element 9 is switched on in a heating zone H.sub.1 with two heating elements 8, 9, a power corresponding to the power input of the second heating element 9 that is switched on or to be switched on is switched off on first heating elements 8 in one or more other heating zones H.sub.1, or switching on such power is blocked.

Methods and systems for reducing substrate particle scratching using machine learning are provided. A machine learning model is trained to predict process recipe settings for a substrate temperature control process to be performed for a current substrate at a manufacturing system. First training data and second training data are generated for the machine learning model. The first training data includes historical data associated with prior process recipe settings for a prior substrate temperature control process performed for a prior substrate at a prior process chamber. The second training data is associated with a historical scratch profile of one or more surfaces of the prior substrate after performance of the prior substrate temperature control process according to the prior process recipe settings. The first training data and the second training data are provided to train the machine learning model to predict which process recipe settings for the substrate temperature control process to be performed for the current substrate correspond to a target scratch profile for one or more surfaces of the current substrate.

A heating circuit includes: an inverter circuit, a heating element, a detection element, a first power supply and a second power supply. The first power supply, the heating element and the inverter circuit form a first loop; the second power supply, the detection element and the heating element form a second loop; the first power supply supplies power to the heating element by means of the first loop, and the heating element generates heat on the basis of the power supply of the first power supply; and the second power supply supplies power to the heating element and the detection element by means of the second loop.

Disclosed is a substrate treating apparatus that performs a heat treatment to a substrate. The apparatus includes the following elements: a heat treating plate; a casing that produces a heat treatment atmosphere by the heat treating plate; a movable top board that is movable between a ceiling surface of the casing and the heat treating plate; and a controller that causes the movable top board to be moved to a raised position when the substrate is loaded/unloaded, and causes the movable top board to be moved to a lowered position when the substrate is placed on the heat treating plate for performing the heat treatment, thereby controlling the lowered position for every substrate.

In a method for a cooktop, in particular for producing and/or operating the cooktop, which has at least one variable cooking surface, the cooking surface is partitioned in an operating mode along a partitioning direction into a plurality of heating zones to which at least one heating parameter is assigned in each case in a location-dependent manner in order to heat a cooking utensil that is deposited on the heating zone. In order to ensure flexible production and/or flexible operation of the cooktop, during partitioning of the cooking surface into the heating zones in at least one peripheral region of the cooking surface, at least one cooking utensil characteristic is taken into account.
