摘要:
An improved analytical method for analysis of dianhydrogalactitol preparations provides a method for determining the purity of dianhydrogalactitol and detecting impurities in preparations of dianhydrogalactitol, as well as identifying any such impurities. The method employs high performance liquid chromatography (HPLC), in particular, HPLC with evaporative light scattering detection (ELSD); the HPLC can be followed by tandem mass spectroscopy. The method can further comprise the step of performing preparative HPLC collection of at least one specific substance peak present in a preparation of dianhydrogalactitol.

The uniformity of the composition of plated solder bumps from one batch of wafers to another is improved by controlling the rotational speed of the wafers based on the particular solder bump pattern. Embodiments include sequentially horizontal fountain electroplating a pattern of solder bumps, e.g., SnAg solder bumps, on a plurality batches of wafers and controlling the rotational speed of each batch of wafers during electroplating based on a calibration plot of the concentration of a solder bump component, e.g., Ag, as a function of rotational speed for each solder bump pattern, such that the uniformity of the Ag concentration in the patterns of solder bumps is greater than 95%, e.g., greater than 98%. Embodiments further include electroplating in the same plater sequential batches of wafers having both different patterns and different solder bump compositions at the same high throughput.

A plant control apparatus includes a plant model and a control input determining device. The plant model estimates a control variable of a plant based on an input including a control parameter to adjust a first control variable of the plant. The control input determining device is configured to correct a temporary value of the control parameter so that a first control variable model value satisfies a predetermined constraint. The control input determining device is configured to determine a control input for the plant based on the temporary value of the control parameter that has been corrected. The first control variable model value is defined as an estimated value of the first control variable calculated by the plant model when the temporary value of the control parameter is input to the plant model.

A plant controller includes a feedback controller configured to calculate a control input provided to a plant so that a control output of the plant matches a target value. The feedback controller includes a controller transfer function that is a transfer function of the feedback controller. The controller transfer function is expressed by a product of an inverse transfer function of a transfer function of a control target model obtained by modeling the plant and a disturbance sensitivity correlation function defined using a sensitivity function. The sensitivity function indicates sensitivity of a disturbance to be applied to the plant with respect to the control output. The sensitivity function is defined by using a response characteristic parameter that indicates a response characteristic of the plant.
