Patent number: 11699667Abstract: A leadframe having extensions around an outer edge of a die pad are disclosed. More specifically, leadframes are created with a flange formed at the outer edge of the die pad and extending away from the die pad. The flange is bent, such that it is positioned at an angle with respect to the die pad. Leadframes are also created with anchoring posts formed adjacent the outer edge of the die pad and extending away from the die pad. The anchoring posts have a central thickness that is less than a thickness of first and second portions opposite the central portion. When the leadframe is incorporated into a package, molding compound completely surrounds each flange or anchoring post, which increases the bond strength between the leadframe and the molding compound due to increased contact area. The net result is a reduced possibility of delamination at edges of the die pad.Type: GrantFiled: May 3, 2021Date of Patent: July 11, 2023Assignee: STMICROELECTRONICS, INC.Inventor: Jefferson Talledo

Patent number: 11695053Abstract: Energy bands of a thin film containing molecular clusters are tuned by controlling the size and the charge of the clusters during thin film deposition. Using atomic layer deposition, an ionic cluster film is formed in the gate region of a nanometer-scale transistor to adjust the threshold voltage, and a neutral cluster film is formed in the source and drain regions to adjust contact resistance. A work function semiconductor material such as a silver bromide or a lanthanum oxide is deposited so as to include clusters of different sizes such as dimers, trimers, and tetramers, formed from isolated monomers. A type of Atomic Layer Deposition system is used to deposit on semiconductor wafers molecular clusters to form thin film junctions having selected energy gaps. A beam of ions contains different ionic clusters which are then selected for deposition by passing the beam through a filter in which different apertures select clusters based on size and orientation.Type: GrantFiled: September 20, 2022Date of Patent: July 4, 2023Assignee: STMICROELECTRONICS, INC.Inventor: John H.

Patent number: 11658098Abstract: The present disclosure is directed to a leadframe package having a side solder ball contact and methods of manufacturing the same. A plurality of solder balls are coupled to recesses in a leadframe before encapsulation and singulation. After singulation, a portion of each solder ball is exposed on sidewalls of the package. This ensures that the sidewalls of the leads are solder wettable, which allows for the formation of stronger joints when the package is coupled to a substrate. This increased adhesion reduces resistance at the joints and also mitigates the effects of expansion of the components in the package such that delamination is less likely to occur. As a result, packages with a side solder ball contact have increased life cycle expectancies.Type: GrantFiled: October 16, 2020Date of Patent: May 23, 2023Assignee: STMicroelectronics, Inc.Inventors: Jefferson Talledo, Tito Mangaoang
