METHOD FOR REDUCING TEMPERATURE TRANSITION IN AN ELECTROSTATIC CHUCK
A method for controlling a substrate temperature in a substrate processing system includes determining a temperature difference between the substrate temperature before the substrate is loaded onto a substrate support device and a desired temperature for the substrate support device and, during a first period, controlling a thermal control element to adjust the temperature of the substrate support device to a temperature value based on the temperature difference. The temperature value is not equal to the desired temperature for the substrate support device. The method further includes loading the substrate onto the substrate support device after the first period begins and before the temperature of the substrate support device returns to the desired temperature and, during a second period that follows the first period, controlling the temperature of the substrate support device to the desired temperature for the substrate support device.
CVD REACTOR WITH A MULTI-ZONE HEATED PROCESS CHAMBER
A device, system and method for depositing crystalline layers on at least one crystalline substrate is described. The disclosure includes the use of a multi zone heater, the multi zone heater is disposed between a reactor housing and a process chamber. The multi zone heater has different electrical properties along its length, whereby the multi zone heater when heated by eddy currents induced by an RF field generated by a RF heating coil provides a temperature profile inside the multi zone heater that varies along the length of the multi zone heater for heating the process chamber.
Pressure control strategies to provide uniform treatment streams in the manufacture of microelectronic devices
The present invention provides techniques to more accurately control the process performance of treatments in which microelectronic substrates are treated by pressurized fluids that are sprayed onto the substrates in a vacuum process chamber control strategies are used that adjust mass flow rate responsive to pressure readings in order to hold the pressure of a pressurized feed constant. In these embodiments, the mass flow rate will tend to vary in order to maintain pressure uniformity.
