Abstract: A method for performing learning is described. A free inference is performed on a learning network for input signals. The input signals correspond to target output signals. The learning network includes inputs that receive the input signals, neurons, weights interconnecting the neurons, and outputs. The learning network is described by an energy for the free inference. The energy includes an interaction term corresponding to interactions consisting of neuron pair interactions. The free inference results in output signals. A first portion of the plurality of weights corresponding to data flow for the free inference. A biased inference is performed on the learning network by providing the input signals to the inputs and bias signals to the outputs. The bias signals are based on the target output signals and the output signals. The bias signals are fed back to the learning network through a second portion of the weights corresponding to a transpose of the first portion of the weights.

Abstract: Techniques herein include methods for forming a direct write, tunable stress film and methods for correcting wafer bow using said stress film. The method can be executed on a coater-developer tool or track-based tool. The stress film can be based on a film that undergoes crosslinking/decrosslinking under external stimulus where direct write is achieved by, but is not limited to, 365 nm exposure and subsequent cure is used to “pattern-in” stress. No develop step may be required, which provides additional significant benefit in conserving film planarity. An amount of bow (or internal stress to create or affect a bow signature) can be tuned with exposure dose, bake temperature, bake time and number of bakes.
