Abstract:
In one embodiment, a semiconductor package includes a generally planar die paddle or die pad that defines multiple peripheral edge segments, and includes one or more tie bars protruding therefrom. In addition, the semiconductor package includes a plurality of leads, portions of which protrude from respective side surfaces of a package body of the semiconductor package. Connected to the top surface of the die pad is at least one semiconductor die which is electrically connected to at least some of the leads. At least portions of the die pad, the leads, and the semiconductor die are encapsulated by the package body. The one or more tie bars and the plurality of leads include downsets that are sized and oriented relative to each other to facilitate enhanced manufacturing.
Abstract:
A semiconductor device has a substrate. A first conductive layer is formed over the substrate. A duplex plated bump on lead pad is formed over the substrate. An insulating layer is formed over the first conductive layer and the substrate. A portion of the insulating over the duplex plated bump on lead pad is removed using a laser direct ablation process. The insulating layer is a lamination layer. The duplex plated bump on lead pad has a wide bump on lead pad. A semiconductor die is mounted over the substrate. The semiconductor die has a composite conductive interconnect structure. The semiconductor die has a first bump and a second bump with a pitch ranging from 90-150 micrometers between the first bump and the second bump. A duplex plated contact pad is formed on a surface of the substrate opposite the duplex plated bump-on-lead pad.

Abstract:
A semiconductor device for use in a printed circuit board is provided. In the semiconductor device, metal pillars are disposed perpendicular to bond pads of a semiconductor die. This configuration eliminates the need to form via holes for the connection of interconnection layers and the bond pads of the semiconductor die, thus simplifying the fabrication procedure of the semiconductor device. In addition, the semiconductor die is embedded in the semiconductor device. Based on this configuration, the use of the semiconductor device in a printed circuit board facilitates the stacking of a plurality of semiconductor dies and can reduce the thickness required for the stack, which make the semiconductor device light in weight and small in thickness and size.
Abstract:
The present invention relates to a pure tone audiometer, and more particularly, to a pure tone audiometer with automated masking which is capable of automatically performing air-conduction and bone-conduction hearing tests and automatically performing a masking test, if necessary, so that a person obtains an accurate pure tone hearing threshold without others' assistance. The pure tone audiometer of the present invention can accurately perform the pure tone hearing test with automated masking without assistance from a doctor or an audiologist. Thus, with the pure tone audiometer, people can easily check their hearing ability for prevention and early detection of hearing loss and take swift action to cure hearing loss.
Abstract:
Disclosed are a composition for introducing the osteogenic differentiation of human embryonic stem cells and a method for differentiating human embryonic stem cells into an osteoblastic lineage by inhibiting the mTOR signaling pathway. When cultured in the presence of an inhibitor of the mTOR signaling pathway, human embryonic stem cells are effectively induced to differentiate into an osteoblastic lineage. The osteogenic differentiation of human embryonic stem cells using the method and the composition is useful in examining the development and differentiation mechanism of osteoblasts and the cause of metabolic bone diseases, including osteoporosis. In addition, the method and the composition can be applied to the development of osteogenic differentiation techniques for generating clinically useful, terminally differentiated mature cells or progenitor cells.
