A heater controller controls power supplied to a heater capable of adjusting the temperature of a placement surface such that the heater reaches a set temperature. A temperature monitor measures the power supplied in the non-ignited state where the plasma is not ignited and in the transient state where the power supplied to the heater decreases after the plasma is ignited, while the power is controlled such that the temperature of the heater becomes constant. A parameter calculator calculates a heat input amount and the thermal resistance by using the power supplied in the non-ignited state and in the transient state to perform a fitting on a calculation model for calculating the power supplied in the transient state. A set temperature calculator calculates the set temperature of the heater at which the wafer reaches the target temperature, using the heat input amount and thermal resistance.

Disclosed herein is a gas delivery assembly for processing a substrate. In one example, a processing chamber comprises a plurality of walls, a bottom, and a lid to form an interior volume. Gas nozzles provide gas into the interior volume. A substrate support is disposed in the interior volume, having a top surface that supports a substrate. A gas delivery assembly comprises a gas manifold, and is disposed outside of the processing chamber. Gas passageways extend from the gas manifold to the gas nozzles, each gas passageway having similar conductance. A controller is fluidically coupled to each of the gas passageways, and is configured to control the timing at which a first process gas flows from the gas delivery assembly through the controller into the gas manifold, and the timing at which a second process gas is injected into the gas manifold through the gas nozzles.

The first reactant is introduced with a subsaturating first dose reaching only a top area of the surface of the one or more gaps and the second reactant is introduced with a saturating second dose reaching a bottom area of the surface of the one or more gaps. A third reactant may be provided to the substrate in the reaction chamber with a third dose, the third reactant reacting with at least one of the first and second reactant.

This disclosure describes a non-dissipative snubber circuit configured to boost a voltage applied to a load after the load's impedance rises rapidly. The voltage boost can thereby cause more rapid current ramping after a decrease in power delivery to the load which results from the load impedance rise. In particular, the snubber can comprise a combination of a capacitive element, two inductive elements, and three switches, where a duty cycle of two of the three switches controls the voltage boost. The snubber can be arranged between a DC power supply and a switching circuit configured to generate a pulsed waveform for provision to the load.

In a method of patterning an integrated circuit, test layer thickness variation data is received when a test layer with a known thickness disposed over a test substrate undergoes tilted angle plasma etching. Overlay offset data per substrate locations caused by the tilted angle plasma etching is determined. The overlay offset data is determined based on the received thickness variation data. The overlay offset data is associated with an overlay between first circuit patterns of a first layer on the semiconductor substrate and corresponding second circuit patterns of a second layer disposed over the first layer on the substrate. A location of the substrate is adjusted based on the overlay offset data during a lithography operation to pattern a resist layer over the second layer. The second layer is patterned based on the projected layout patterns of the reticle and using the tilted angle plasma etching.

A plasma etching method is disclosed. The plasma etching method comprises: a first step of vaporizing liquid perfluoroisopropyl vinylether (PIPVE); a second step of supplying, to a plasma chamber in which an object to be etched is arranged, the vaporized PIPVE and a discharge gas comprising argon gas; and a third step of discharging the discharge gas so as to generate plasma, and using same so as to plasma-etch the object to be etched.
