    摘要: The present invention relates to methods for detecting gases in an environment using chemical and thermal sensing. In one embodiment, a method includes exposing a chemiresistor embedded within a sensor pixel to a gas in an environment; setting a heater embedded within the sensor pixel to a sensing temperature, the sensing temperature being greater than room temperature; measuring an electrical resistance of the chemiresistor in response to setting the heater to the sensing temperature; and in response to a difference between the electrical resistance of the chemiresistor and a reference electrical resistance being less than a threshold, supplying a fixed power input to the heater embedded within the sensor pixel and measuring a temperature of the sensor pixel relative to a reference temperature.

    摘要: Semiconductor manufacturing processes include providing a first substrate having a first passivation layer disposed above a patterned top-level metal layer, and further having a second passivation layer disposed over the first passivation layer; the second passivation layer has a top surface. The processes further include forming an opening in a first portion of the second passivation layer, and the opening exposes a portion of a surface of the first passivation layer. The processes further include patterning the second and first passivation layers to expose portions of the patterned top-level metal layer and bonding a second substrate and the first substrate to each other. The bonding occurs within a temperature range in which at least the exposed portion of the first passivation layer undergoes outgassing.
