Abstract:
Systems and methods may be provided for coupling together semiconductor devices. One or more of the semiconductor devices may be provided with an array of bump contacts formed in an etch back process. The bump contacts may be indium bumps. The indium bumps may be formed by depositing a sheet of indium onto a surface of a device substrate, depositing and patterning a layer of photoresist over the indium layer, and selectively etching the indium layer to the surface of the substrate using the patterned photoresist layer to form the indium bumps. The substrate may be an infrared detector substrate. The infrared detector substrate may be coupled to a readout integrated circuit substrate using the bumps.

The invention relates to a contact bump connection (24) and to a method for producing a contact bump connection between an electronic component provided with at least one terminal face (11) and a contact substrate (26) contacted with the component and having at least one second terminal face (25), wherein the first terminal face is provided with a contact bump (10) which has a raised edge (15) and has at least one displacement pin (16) in a displacement compartment (18) which is surrounded by the raised edge and is open towards a head end of the contact bump, and in a contact region (31) with the first terminal face the second terminal face has a contact bead (30) which is formed by displacement of a contact material (29) of the second terminal face into the displacement compartment and surrounds the displacement pin, wherein said contact bead has a bead crown (33) which is directed to a base (17) of the displacement compartment and is raised relative to a level contact surface (32) of the second terminal face surrounding the contact region.
Abstract:
Disclosed herein is a processing method of a microelectrode array. A processing method of a microelectrode array includes: depositing a sacrificial layer on a silicon substrate; patterning a first polymer on the deposited sacrificial layer and then thermally curing the first polymer patterning a metal thin film on the first polymer to form a bonding pad site, an interconnection line and a recording pad site; closing the interconnection line site and coating a second polymer to pattern the bonding pad site and the recording pad site; depositing a seed layer on the second polymer and the metal thin film using a sputter; electroplating a metal on the bonding pad site and the recording pad site, thereby forming an electroplated layer; patterning a photoresist to open an upper portion of the electroplated layer; depositing platinum on the photoresist and the electroplated layer; and removing the photoresist.
Abstract:
Some embodiments include a planarization method. A liner is formed across a semiconductor substrate and along posts that extending upwardly from the substrate. Organic fill material is formed over the liner and between the posts. A planarized surface is formed which extends across the posts and across one or both of the liner and the fill material. Some embodiments include a semiconductor construction containing a semiconductor die. Electrically conductive posts extend through the die. The posts have upper surfaces above a backside surface of the die, and have sidewall surfaces extending between the backside surface and the upper surfaces. A liner is across the backside surface of the die and along the sidewall surfaces of the posts. Electrically conductive caps are over the upper surfaces of the posts, and have rims along the liner adjacent the sidewall surfaces of the posts.
