  • Patent number: 11973040
    Abstract: A method is provided for forming an integrated circuit (IC) chip package structure. The method includes providing a substrate for an interposer, and forming a conductive interconnect structure in and on the substrate for connecting a group of selected IC dies. The method includes forming warpage-reducing trenches in non-routing regions of the interposer, wherein the warpage-reducing trenches are sized and positioned based on a warpage characteristic to reduce the warpage of the chip package structure. The method also includes depositing a warpage-relief material in the warpage-reducing trenches according to the warpage characteristic to reduce the warpage of the chip package structure, and bonding the group of selected IC dies to the interposer to form a chip package structure.

  • Publication number: 20240136183
    Abstract: A photo resist layer is used to protect a dielectric layer and conductive elements embedded in the dielectric layer when patterning an etch stop layer underlying the dielectric layer. The photo resist layer may further be used to etch another dielectric layer underlying the etch stop layer, where etching the next dielectric layer exposes a contact, such as a gate contact. The bottom layer can be used to protect the conductive elements embedded in the dielectric layer from a wet etchant used to etch the etch stop layer.

  • Publication number: 20220226553
    Abstract: A hemodialysis enhancement apparatus involves a bladder having elastically deformable surface that forms a variable volume therewithin. The elastically deformable surface has a smooth interior surface such that blood cannot collect to form a blood clot. The hemodialysis enhancement apparatus further includes a rigid housing having a wall surrounding the bladder and defining a housing volume such that a) when the variable volume chamber has a volume equal to the first volume, most of the elastically deformable surface will be spaced apart from the wall, and b) when the variable volume chamber has a volume equal to the second volume, a substantial portion of the elastically deformable surface will abut the wall. A method performed within a hemodialysis system involves, during an initial phase, withdrawing a volume of a patient's blood into a hemodialysis enhancer, and during a subsequent phase, translocating the patient's blood back into the patient's circulation.
