Substrate holding device
Provided is a substrate holding device that inhibits drop in holding accuracy of a substrate. A Bernoulli chucking pad suctions and holds a front surface or a back surface of a substrate S. A position determiner 54 is capable of pushing the substrate S in contact with a side surface 82 of the substrate S, and positioning the suctioned substrate S. A pin 66 enables the position determiner 54 to come in contact with the side surface 82 of the substrate S. The pin 66 brings the position determiner 54 into contact with the side surface 82 of the substrate S, and the position determiner 54 thereby positions the substrate S.
Dual wafer plating fixture for a continuous plating line
A wafer plating fixture for use in simultaneously electroplating a two substrates. The wafer plating fixture including: an electrically conductive carrier bus; a plurality of contact clips electrically coupled to the carrier bus and configured to hold the two substrates in place and electrically couple the two substrates to the carrier bus; and a non-conductive substrate backer to separate the two substrates coupled to the carrier bus. A method of electroplating a plurality of substrates. The method including: mounting two substrates to be plated onto a wafer plating fixture; mounting the wafer plating fixture on a continuous belt of plating system; dipping the wafer plating fixture with the two substrates held thereon into an electroplating bath; and applying a voltage to the two substrates via the wafer plating fixture.
Method of plating
There is provided a method of plating comprising: a process of bringing a sealing portion of a seal provided to prevent a contact of a substrate holder that holds a substrate from coming into contact with a plating solution, into contact with pure water; and a process of detecting a leak of the seal, based on presence or absence of a short circuit of a leak detection electrode placed inside of the substrate holder after the sealing portion is brought into contact with the pure water and before the substrate is brought into contact with a chemical solution.

Method and apparatus for uniformly metallization on substrate
The present invention relates to applying at least one ultra/mega sonic device and its reflection plate for forming standing wave in a metallization apparatus to achieve highly uniform metallic film deposition at a rate far greater than conventional film growth rate in electrolyte. In the present invention, the substrate is dynamically controlled so that the position of the substrate passing through the entire acoustic field with different power intensity in each motion cycle. This method guarantees each location of the substrate to receive the same amount of total sonic energy dose over the interval of the process time, and to accumulatively grow a uniform deposition thickness at a rapid rate.

Detection of Contact Formation Between a Substrate and Contact Pins in an Electroplating System
The present disclosure relates to an electroplating system including a first contact detection sensor and a second contact detection sensor disposed at a surface of a cone of the electroplating system. The first contact detection sensor detects a first resistance at a first contact between a substrate to be plated by the electroplating system and a first contact pin, the second contact detection sensor detects a second resistance at a second contact between the substrate and a second contact pin. A controller receives the first resistance and the second resistance, and determines the first contact and the second contact are not properly formed when a difference between the first resistance and the second resistance is not within a first predetermined resistance range, or the first resistance or the second resistance is not within a second predetermined resistance range.
