Abstract: Provided is a single-axis pointing pure magnetic control algorithm for a spacecraft based on geometrical analysis to realize single-axis pointing control of the spacecraft through the pure magnetic control algorithm in which a magnetic torque is only output by a magnetorquer to interact with a geomagnetic field to generate a control torque. The algorithm uses a spatial geometry method to obtain an optimally controlled magnetic torque direction, thereby designing a PD controller. The problem that the traditional magnetic control method is low in efficiency and even cannot be controlled is overcome. The algorithm is simple and easy, can be used in the attitude control field of spacecrafts, and achieves the pointing control in point-to-sun of a solar array and point-to-ground of antennae.

Abstract: A method of forming a passivation layer on an integrated circuit (IC) chip including a device layer on a substrate. The method may include forming a crosslinked precursor passivation layer on the IC chip, and curing the crosslinked precursor passivation layer at a first temperature to form a passivation layer. The method may further include maintaining the device layer at a second, lower temperature during the curing of the crosslinked precursor passivation layer. Maintaining the device layer at the second, lower temperature may mitigate and/or prevent damage to the device layer conventionally caused by exposure to the first temperature during the curing of the crosslinked precursor passivation layer. The method may include using a curing system including a chamber, an infrared source for controlling the first temperature for curing the crosslinked precursor passivation layer, and a temperature control device for controlling the second, lower temperature of the device layer.
