20090230528 | Support Mounted Electrically Interconnected Die Assembly - Stacked die assemblies are electrically connected to connection sites on any support, without electrical connection to any interposed substrate or leadframe, and without solder. | 09-17-2009 |
20100052087 | Image Sensor - An image sensor die includes a conformal dielectric coating over at least a die sidewall adjacent an interconnect edge and, in some embodiments, a conformal dielectric coating over the image array area of the front side of the die. The die can be connected to circuitry in a support by an electrically conductive material that is applicable in a flowable form, such as a curable electrically conductive polymer, which is applied onto or adjacent the dielectric coating on the die sidewall, and which is cured to complete connection between interconnect pads on the die and exposed sites on the support circuitry. The coating over the image array area, at least, is substantially transparent to visible light, and provides mechanical and chemical protection for underlying structures in and on the image sensor. Also, a package contains such an image sensor die mounted on and electrically connected to a support; and assemblies include such an image sensor die and additional die mounted on and electrically connected to opposite sides of a support. Also, methods are disclosed for making the image sensor die, packages, and assemblies. | 03-04-2010 |
20100117224 | Sensor - A sensor die in a sensor device includes a conformal dielectric coating over at least a die sidewall adjacent an interconnect edge and, in some devices, a conformal dielectric coating over at least part of the active area of the front side of the die. The sensor die can be connected to circuitry in a support by an electrically conductive material that is applicable in a flowable form, such as a curable electrically conductive polymer, which is applied onto or adjacent the dielectric coating on the die sidewall, and which is cured to complete connection between interconnect pads on the die and exposed sites on the support circuitry. In some devices, a coating over the active area of the sensor die provides mechanical and chemical protection for underlying structures in and on the die. In an image sensor device, for example, the coating over the image sensor array on the die is substantially optically transparent. Also, a package contains such a sensor die mounted on and electrically connected to a support; and assemblies include such a sensor die and additional die mounted on and electrically connected to opposite sides of a support. Also, methods are disclosed for making the sensor die, devices, packages, and assemblies. | 05-13-2010 |
20110037159 | Electrically Interconnected Stacked Die Assemblies - In die stack assembly configurations successive die in the stack are offset at a die edge at which die pads are situated, and the die are interconnected by electrically conductive traces. In some embodiments the electrically conductive traces are formed of an electrically conductive polymer. An electrically insulative conformal coating is provided having openings at die pads that are electrically connected. | 02-17-2011 |
20110147943 | WAFER LEVEL SURFACE PASSIVATION OF STACKABLE INTEGRATED CIRCUIT CHIPS - An electrically insulative conformal coating is applied at least to the active (front) side and one or more sidewalls of the die during wafer processing. Also, a die has an electrically insulative conformal coating applied to at least the active (front) side and sidewalls. Also, assemblies include a stack of such die, electrically interconnected die-to-die; and assemblies include such a die or a stack of such die, electrically interconnected to underlying circuitry (for example in a substrate or a circuit board). | 06-23-2011 |
20110272825 | STACKED DIE ASSEMBLY HAVING REDUCED STRESS ELECTRICAL INTERCONNECTS - Methods are disclosed for improving electrical interconnection in stacked die assemblies, and stacked die assemblies are disclosed having structural features formed by the methods. The resulting stacked die assemblies are characterized by having reduced electrical interconnect failure. | 11-10-2011 |
20130099392 | Support mounted electrically interconnected die assembly - Stacked die assemblies are electrically connected to connection sites on any support, without electrical connection to any interposed substrate or leadframe, and without solder. | 04-25-2013 |
20140213020 | SEMICONDUCTOR DIE MOUNT BY CONFORMAL DIE COATING - A conformal coating on a semiconductor die provides adhesion between the die and a support. No additional adhesive is necessary to affix the die on the support. The conformal coating protects the die during assembly, and serves to electrically insulate the die from electrically conductive parts that the die may contact. The conformal coating may be an organic polymer, such as a parylene, for example. Also, a method for adhering a die onto a support, which may optionally be another die, includes providing a coating of a conformal between the die and the support, and heating the coating between the die and the support. The conformal coating may be provided on a die attach area of a surface of the die, or on a die mount region of a surface of the support, or on both a die attach area of a surface of the die and on a die mount region of a surface of the support; and the conformal coating may be provided following placement of the die on the support. | 07-31-2014 |
