Abstract
Abstract A semiconductor device comprising a semiconductor unit with leads extending therefrom is placed on a bottom packaging tray having a die-shaped upper surface. A top lubricating type film is used over the device 10 and below a punch unit that is used to bend the leads. A process of assembling the semiconductor device on a die type package is disclosed which includes placing the semiconductor device with leads on a packaging tray with upper lead-shaped baring surfaces, placing an anti-friction film sheet over the tray and over the device with its leads extending therefrom, and actuating a punch unit disposed above the film sheet, thereby forming or bending the leads and simultaneously using the die type tray for packaging the semiconductor device.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
78 words
A method for providing a packaged semiconductor device including the steps of: placing a semiconductor device which has a plurality of straight leads in a die-shaped tray; and bending said plurality of leads by using a punch to shape said plurality of leads into the configuration of said die-shaped tray; further including the step of first placing an anti-friction film sheet above the tray above the semiconductor device and under the punch prior to the lead bending step.
Claim 2
Independent Claim
78 words
A method for providing a packaged semiconductor device including the steps of: placing a semiconductor device which has a plurality of straight leads in a die-shaped tray; and bending said plurality of leads by using a punch to shape said plurality of leads into the configuration of said die-shaped tray; further including the step of first placing an anti-friction film sheet above the tray above the semiconductor device and under the punch prior to the lead bending step.
Claim 3
Dependent Claim
30 words
The method of claim 1 including the step of actuating the punch thereby forming the leads while using said sheet as both a punch lubricant and a barrier of contamination.
Claim 4
Dependent Claim
24 words
The method of claim 2 including the step of leaving the semiconductor device in contact with the tray as a package for said device.
Claim 5
Dependent Claim
21 words
The method of claim 3 including the step of off-loading the device with its supporting tray package after the punch operation.
Claim 6
Dependent Claim
28 words
The method of claim 11 including the step of: forming the tray from an impact-resistant plastic material before the step of placing the semiconductor device in the tray.
Claim 7
Dependent Claim
29 words
The method of claim 1 including the step of: forming the film sheet from an anti-friction plastic material before the step of placing the film sheet above the tray.
Claim 8
Dependent Claim
23 words
The method of claim 6 including the step of: removing the plastic film sheet after the step of bending said plurality of leads.
Claim 9
Independent Claim
84 words
A method for packaging a semiconductor device comprising a semiconductor portion and a plurality of straight leads, including steps of: placing said semiconductor device in a container comprising unitary die-shaped tray means which include a base portion supporting said semiconductor portion of said semiconductor device and edge walls extending above said semiconductor device, and bending said plurality of straight leads of said semiconductor device by using a punch to shape said plurality of straight leads into the configuration of said die shaped tray means.
Claim 10
Independent Claim
84 words
A method for packaging a semiconductor device comprising a semiconductor portion and a plurality of straight leads, including steps of: placing said semiconductor device in a container comprising unitary die-shaped tray means which include a base portion supporting said semiconductor portion of said semiconductor device and edge walls extending above said semiconductor device, and bending said plurality of straight leads of said semiconductor device by using a punch to shape said plurality of straight leads into the configuration of said die shaped tray means.
Claim 11
Dependent Claim
39 words
The method of claim 8 further including placing a plurality of said semiconductor devices in said container with each one of said plurality of semiconductor devices being placed on its own base portion of its own die-shaped tray means.
Claim 12
Independent Claim
89 words
A method for packaging a semiconductor device including the steps of: placing a semiconductor device which has a plurality of straight leads in a die-shaped tray means which includes a base portion supporting said semiconductor device and edge walls extending above said semiconductor device, placing a film sheet above said die-shaped tray means, and bending said plurality of leads by using a punch in contact with said film sheet to shape said plurality of straight leads located beneath said film sheet into the configuration of said die-shaped tray means.
Claim 13
Independent Claim
89 words
A method for packaging a semiconductor device including the steps of: placing a semiconductor device which has a plurality of straight leads in a die-shaped tray means which includes a base portion supporting said semiconductor device and edge walls extending above said semiconductor device, placing a film sheet above said die-shaped tray means, and bending said plurality of leads by using a punch in contact with said film sheet to shape said plurality of straight leads located beneath said film sheet into the configuration of said die-shaped tray means.
