Publication number: 20100078769Abstract: In a semiconductor device for use in a wafer level chip scale package (WLCSP) and a method for fabrication, an inner scribe seal is formed around a functional circuit area that does not extend all the way into the corners of the rectangular die, and an outer scribe seal follows the perimeter of the die and into the corners, with the outer scribe seal having a continuous barrier wall towards the die edges so that moisture penetration in dielectric layers of the die is minimized, and cracks and delamination are stopped near the die edges. Limiting the extent of the insulating layer or layers in the WLCSP to cover the functional circuit area also reduces the stresses caused by these layers near the die corners. Other features further enhance the strength and barrier properties of the scribe seals and the layers near the die corners, terminate cracks and delamination at various levels within the dielectric stack of the die and the die protective overcoat, and prevent damage during the WLCSP assembly process.Type: ApplicationFiled: September 23, 2009Publication date: April 1, 2010Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Jeffrey A.

Publication number: 20100078770Abstract: A three dimensional device stack structure comprises two or more active device and interconnect layers further connected together using through substrate vias. Methods of forming the three dimensional device stack structure comprise alignment, bonding by lamination, thinning and post thinning processing. The via features enable the retention of alignment through the lamination process and any subsequent process steps thus achieving a mechanically more robust stack structure compared to the prior art.Type: ApplicationFiled: September 26, 2008Publication date: April 1, 2010Applicant: International Business Machines CorporationInventors: Sampath Purushothaman, Mary E.

Publication number: 20100078772Abstract: Metallised through silicon vias located in the scribe lanes between die are used to create an electrical connection between the front-side and the rear-side of a silicon die. One of the metallisation layers on the front-side of the die comprises portions which extend into the scribe lanes to form capture pads for the through silicon vias. The rear-side of the wafer is metallised and this metallisation may, in some embodiments, be patterned to form tracks or components. The silicon die may be used to create improved package on package devices. In other examples, other substrate materials may be used.Type: ApplicationFiled: September 11, 2009Publication date: April 1, 2010Applicant: Cambridge Silicon Radio Ltd.Inventor: Peter John Robinson
