Publication number: 20120248614Abstract: Methods of forming a Ni material on a bond pad are disclosed. The methods include forming a dielectric material over a bond pad, forming an opening within the dielectric material to expose the bond pad, curing the dielectric material to form a surface of the dielectric material having a steep curvilinear profile, and forming a nickel material over the at least one bond pad. The dielectric material having a steep curvilinear profile may be formed by altering at least one of a curing process of the dielectric material and a thickness of the dielectric material. The dielectric material may be used to form a relatively thick Ni material on bond pads smaller than about 50 ?m. Semiconductor structures formed by such methods are also disclosed.Type: ApplicationFiled: March 29, 2011Publication date: October 4, 2012Applicant: MICRON TECHNOLOGY, INC.Inventors: Jaspreet S.

Publication number: 20120228778Abstract: A through via (144) contains a conductor (244, 276) passing through a substrate (140) for connection to an integrated circuit element. The through via consists of two segments (144.1, 144.2) formed from respective different sides (140.1, 140.2) of the substrate and meeting inside the substrate. Each segment is shorter than the entire via, so via formation is facilitated. The second segment is etched after deposition of an etch stop layer (214) into the first segment. Due to the etch stop layer, the first segment's depth does not have to be rigidly controlled. The conductor is formed by separate depositions of conductive material into the via from each side of the substrate. From each side, the conductor is deposited to a shallower depth than the via depth, so the deposition is facilitated. Other embodiments are also provided.Type: ApplicationFiled: March 7, 2011Publication date: September 13, 2012Inventors: Valentin Kosenko, Sergey Savastiouk

Patent number: 8258053Abstract: In sophisticated semiconductor devices including transistors having a high-k metal gate electrode structure, disposable spacers may be provided on the encapsulating spacer element with a reduced width so as to not unduly increase a lateral offset of a strain-inducing material to be incorporated into the active region. For this purpose, a multi-layer deposition may be used in combination with a low pressure CVD process.Type: GrantFiled: October 8, 2010Date of Patent: September 4, 2012Assignee: GLOBALFOUNDRIES Inc.Inventors: Stephan Kronholz, Matthias Kessler, Andreas Kurz

Publication number: 20120211884Abstract: A method and structure for forming a semiconductor device, for example a device including a wafer chip scale package (WCSP), can include the formation of at least one conductive layer which contacts a bond pad. The at least one conductive layer can be patterned using a first mask, then a passivation layer can be formed over the patterned at least one conductive layer. The passivation layer can be patterned using a second mask to expose the at least one conductive layer, then a conductive layer such as a solder ball, conductive bump, metal-filled paste, or another conductor is formed on the at least one conductive layer. The method can result in a structure which is formed using a reduced number of mask steps.Type: ApplicationFiled: February 23, 2011Publication date: August 23, 2012Inventors: Frank Stepniak, Christopher Daniel Manack, Licheng M.

Publication number: 20120206685Abstract: Disclosed is an electrode film which does not exfoliate from, or diffuse into, an oxide semiconductor or an oxide thin film. An electrode layer comprises a highly adhesive barrier film being a Cu—Mg—Al thin film and a copper thin film; and an oxide semiconductor and an oxide thin film contact with the highly adhesive barrier film. With the highly adhesive barrier film having magnesium in a range of at least 0.5 at % but at most 5 at % and aluminum at least 5 at % but at most 15 at % when the total number of atoms of copper, magnesium, and aluminum is 100 at %, the highly adhesive barrier film has both adhesion and barrier properties. The electrode layer is suitable because a source electrode layer and a drain electrode layer contact the oxide semiconductor layer. A stopper layer having an oxide may be provided on a layer under the electrode layer.Type: ApplicationFiled: February 22, 2012Publication date: August 16, 2012Applicant: ULVAC, INC.,Inventors: Satoru TAKASAWA, Masanori SHIRAI, Satoru ISHIBASHI
