Title: Offset snip
Inventor: KEEFFE JAMES R O
IPC: B23D29/02
Filed: 1984-07-23
Granted: 1990-07-21
Abstract: The offset shears use two articulated blades (12,14) connected by a fulcrum pin through aligned holes (60,64). The blades may act as rocking levers pinned to hand levers in an elbow-joined mechanism. Contact between the blades, other than via the cutting eges during the closure movement is via bearing faces incorporated on bosses (92,94) and offset from the respective blade bodies (62,66). The arrangement allows material to be removed from the blades by grinding, e.g. to reform the cuting edges (70,72), material also being removed from the bosses, the anvil and the chisel to maintain the relationship between the cutting edges. A tooth in the lower blade facilitates the cutting circles.

Abstract: The field oxide layer is formed  by;  thermally  growing  pad oxide and adding nitride; removing nitride over a field region  to define active regions; adding side  walls  on  remaining  nitride; doping the field region using  the  spacers  as  a  mask;  growing thermal field oxide on the exposed substrate in the field  region; removing remaining nitride; and reducing step coverage problem  in the field oxide layer by etchback. Size of bird's beak and  stress can be reduced at the edges of the field region.  A  heavil  doped channel stop layer is formed only  in  the  middle  of  the  field region so that breakdown and punch through are reduced.
