Abstract:
A method of making a micro-transfer printed system includes providing a source wafer (10) having a plurality of micro-transfer printable source devices (12 arranged at a source spatial density; providing an intermediate wafer (20) having a plurality of micro-transfer printable intermediate supports (24) arranged at an intermediate spatial density less than or equal to the source spatial density; providing a destination substrate (30); micro-transfer printing the source devices from the source wafer to the intermediate supports of the intermediate wafer with a source stamp having a plurality of posts at a source transfer density to make an intermediate device (22) on each intermediate support; and micro-transfer printing the intermediate devices from the intermediate wafer to the destination substrate at a destination spatial density less than the source spatial density with an intermediate stamp having a plurality of posts at an intermediate transfer density less than the source transfer density.
Abstract:
A package on package (PoP) device that includes a first package, a second package that is coupled to the first package, and at least one gap controller located between the first package and the second package, where the at least one gap controller is configured to provide a minimum gap between the first package and the second package. The first package includes a first electronic package component (e.g., first die). In some implementations, the at least one gap controller is coupled to the first package, but free of coupling with the second package. The at least one gap controller is located on or about a center of the first package. The at least one gap controller may be located between the first electronic package component (e.g., first die) and the second package. The package on package (PoP) device may include an encapsulation layer between the first package and the second package.
Abstract:
A method of removing at least a portion of a layer of material from over a semiconductor substrate that can include dispensing an etching solution over the semiconductor substrate to form a pool of etching solution on the layer of material, wherein a footprint of the pool of etching solution is less than a footprint of the semiconductor substrate. The pool of etching solution and the semiconductor substrate can be moved with respect to each other. A pool boundary of the pool of etching solution can be defined on the semiconductor substrate with at least one air-knife such that the pool of etching solution etches the layer of material over the semiconductor substrate within the footprint of the pool of etching solution. The etching solution and at least a portion of the layer of material etched by the etching solution can be removed with the at least one air-knife.
Abstract:
In a multi-chip module (MCM), a "super" chip (110N) is attached to multiple "plain" chips (110F' "super" and "plain" chips can be any chips). The super chip is positioned above the wiring board (WB) but below at least some of plain chips (110F). The plain chips overlap the super chip. Further, the plain chips' low speed IOs can be connected to the WB by long direct connections such as bond wires (e.g. BVAs) or solder stacks; such connections can be placed side by side with the super chip. Such connections can be long, so the super chip is not required to be thin. Also, if through-substrate vias (TSVs) are omitted, the manufacturing yield is high and the manufacturing cost is low. Other structures are provided that combine the short and long direct connections to obtain desired physical and electrical properties.
