An improved wire bonding capillary used in the bonding of wires to the bond pads of a semiconductor device and the leads of a lead frame, the wire bonding capillary having a working tip having a working surface including a flat annular portion surrounding the wire feed aperture in the capillary and a concave surface extending therefrom to the intersection with the radius extending from the external tip diameter of the working tip.

Concave face wire bond capillary and method

A semiconductor die package having an elastomeric substrate with a first support frame and a second support frame. The first support frame has a cavity within which a semiconductor die is placed. The second support frame may have an optional cavity. The optional cavity in the second support frame may have an optional rigid structure. The rigid structure may have a heating element formed within it.

Method of forming a support frame for semiconductor packages

A method and apparatus for achieving a level exposed surface of a viscous material pool for applying viscous material to at least one semiconductor component by contacting at least a portion of the semiconductor component with viscous material within a reservoir. A level viscous material exposed surface is achieved by using at least one mechanism in association with the reservoir. The mechanism is configured to level the exposed surface of viscous material and maintain the exposed surface at a substantially constant level. The reservoir may be shaped such that the exposed surface of viscous material is supplied to a precise location.

A method and apparatus for application of adhesive tape to semiconductor devices are discolsed. A first adhesively coated tape material length is supplied to a first die associated with a cutting and application mechanism. A second length of adhesively coated tape material is also provided to a second die of the cutting and application mechanism. A plurality of LOC leadframes is supplied sequentially through the application structure to apply a first decal cut from the first tape material to a first die site at a first location and to apply a second decal cut from the second tape material to a second die site at a second location.

Apparatus for application of adhesive tape to semiconductor devices

A method for applying a viscous material to a lead frame element. A method of the invention includes positioning the lead frame facing downward and bringing the lead fingers into contact with a pool of adhesive material. The contact of the lead fingers to the adhesive material results in a portion of the lead fingers receiving a portion of the adhesive material from the pool of adhesive material. The gravitational forces on the adhesive material on the downward facing lead frame maintain the shape and boundary definition of the adhesive material.

Method for applying adhesives to a lead frame

A method for singulating a substrate containing semiconductor components is performed using a nest for holding the substrate, a prestage alignment base for aligning the substrate during a prestage alignment step, and a vacuum cutting base for holding the nest and the substrate during a cutting step. The prestage alignment base includes locator pins configured to engage locator openings on the substrate to align the substrate on the nest. As the cutting base does not include the locator pins, the cutting step can be performed without saw scrap collecting on the locator pins. A system for performing the method includes the nest and the prestage alignment base having the locator pins configured to engage the locator openings on the substrate. The system also includes the sawing base which includes pedestals with vacuum conduits for holding the substrate stationary on the nest for sawing. The system also includes the saws, and a vacuum source in flow communication with the vacuum conduit and pedestals on the sawing base.

Method and system for singulating semiconductor components

A semiconductor package singulation process is disclosed. The process comprises the step of using at least a portion of a reference fiducial formed on at least one package in a semiconductor package panel comprising a plurality of interconnected packages, the fiducial used to monitor and to control the semiconductor package singulation process.
