Publication number: 20120168947Abstract: Methods for localized thinning of wafers used in semiconductor devices and the structures formed from such methods are described. The methods thin localized areas of the backside of the semiconductor wafer to form recesses with a bi-directional channel design that is repeated within the wafer (or die) so that no straight channel line crosses the wafer (or die). The bi-directional pattern design keeps the channels from being aligned with the crystal orientation of the wafer. The recesses are then filled by a solder ball drop process by dropping proper size solder balls into the recesses and then annealing the wafer to reflow the solder balls and flatten them out. The reflow process begins to fill in the recesses from the bottom up, thereby avoiding void formation and the resulting air traps in the reflowed solder material. Other embodiments are also described.Type: ApplicationFiled: February 24, 2012Publication date: July 5, 2012Inventors: Suku Kim, James J. Murphy, Michael D. Gruenhagen, Matthew R. Reynolds, Romel N.

Patent number: 8143125Abstract: A method for forming a trench-gate FET includes the following steps. A plurality of trenches is formed extending into a semiconductor region. A gate dielectric is formed extending along opposing sidewalls of each trench and over mesa surfaces of the semiconductor region between adjacent trenches. A gate electrode is formed in each trench isolated from the semiconductor region by the gate dielectric. Well regions of a second conductivity type are formed in the semiconductor region. Source regions of the first conductivity type are formed in upper portions of the well regions. After forming the source regions, a salicide layer is formed over the gate electrode in each trench abutting portions of the gate dielectric. The gate dielectric prevents formation of the salicide layer over the mesa surfaces of the semiconductor region between adjacent trenches.Type: GrantFiled: March 27, 2009Date of Patent: March 27, 2012Assignee: Fairchild Semiconductor CorporationInventors: Robert J.

Patent number: 8129778Abstract: Semiconductor devices and methods for making such devices that are especially suited for high-frequency applications are described. The semiconductor devices combine a SIT (or a junction field-effect transistor [JFET]) architecture with a PN super-junction structure. The SIT architecture can be made using a trench formation containing a gate that is sandwiched between thick dielectric layers. While the gate is vertically sandwiched between the two isolating regions in the trench, it is also connected to a region of one conductivity type of the super-junction structure, thereby allowing control of the current path of the semiconductor device. Such semiconductor devices have a lower specific resistance and capacitance relative to conventional planar gate and recessed gate SIT semiconductor devices. Other embodiments are described.Type: GrantFiled: December 2, 2009Date of Patent: March 6, 2012Assignee: Fairchild Semiconductor CorporationInventors: Suku Kim, James J. Murphy, Gary Dolny

Patent number: 8058732Abstract: Disclosed are semiconductor die structures that enable a die having a vertical power device to be packaged in a wafer-level chip scale package where the current-conducting terminals are present at one surface of the die, and where the device has very low on-state resistance. In an exemplary embodiment, a trench and an aperture are formed in a backside of a die, with the aperture contacting a conductive region at the top surface of the die. A conductive layer and/or a conductive body may be disposed on the trench and aperture to electrically couple the backside current-conducting electrode of the device to the conductive region. Also disclosed are packages and systems using a die with a die structure according to the invention, and methods of making dice with a die structure according to the invention.Type: GrantFiled: November 20, 2008Date of Patent: November 15, 2011Assignee: Fairchild Semiconductor CorporationInventors: Michael D.
