The present invention relates generally to a new method of repairing electrical lines, and more particularly to repairing electrical lines having an opening at the module level with devices in place. Various methods and processes are used to repair this open or defective portion in an electrical conductor line. It could be repaired by securing a jumper wire or nugget across the open or the repair could be made by a deposition process, which includes but is not limited to filling the opening with a solder type material or inserting a solder coated electrical wire and heating the solder and allowing the solder to melt and repair the open. One of the attributes of this invention is the ability to repair on a substrate or module on which active components such as chips, and passive components such as pins, capacitors, etc. have been attached. The invention also allows repair of fine line patterns which are normally not repairable by conventional techniques.

The invention generally relates to a design structure of a circuit design, and more particularly to a design structure of a delamination sensor for use with low-k materials. A delamination sensor includes at least one first sensor formed in a layered semiconductor structure and a second sensor formed in the layered semiconductor structure. The at least one first sensor is structured and arranged to detect a defect, and the second sensor is structured and arranged to identify an interface where the defect exists.

Radiation-curable compositions are provided for use in the fabrication of electronic components as passivation coatings; for defect repair in ceramic and thin film products by micropassivation in high circuit density electronic modules to allow product recovery; as a solder mask in electronic assembly processes; for use as protective coatings on printed circuit board (PCB) circuitry and electronic devices against mechanical damage and corrosion from exposure to the environment. The compositions are solvent-free, radiation-curable, preferably uv-curable, containing a polymer binder, which is a pre-formed thermoplastic or elastomeric polymer/oligomer, a monofunctional and/or bifunctional acrylic monomer, a multifunctional (more than 2 reactive groups) acrylated/methacrylated monomer, and a photoinitiator, where all the constituents are mutually miscible forming a homogeneous viscous blend without the addition of an organic solvent. The compositions may also contain inorganic fillers and/or nanoparticle fillers.
摘要:
A device repair process that includes removing a passivation polyimide layer. The passivation polyimide layer is removed using a first-half ash followed by a second-half ash. The device is rotated during the second-half ash. The device is then cleaned using sodium hydroxide (NaOH) and a subsequent light ash step is implemented. After the passivation polyimide layer is removed, a seed layer is deposited on the device. A photoresist is formed on the seed layer and bond sites are formed in the photoresist. Repair metallurgy is plated through the bond sites. The bond sites are plated by coupling the device to a fixture and applying the current for plating to the fixture. The contact between the device and the fixture is made though bottom surface metallurgy. After plating, the residual seed layer is removed and a laser delete process is implemented to disconnect and isolate the nets of the device.
