Filed:

Sep 18, 1979

Appl. No.:

6/076645

Inventors:

Joseph M. Jacobs - Berwyn IL

Assignee:

Zenith Radio Corporation - Glenview IL

International Classification:

B21F 100

US Classification:

140105

Abstract:

A method is disclosed for the temporary retention of insulated electrical leads by a printed circuit board preparatory to permanent electrical and mechanical attachment. Also disclosed is apparatus for forming the leads for said retention. The lead has a metallic wire therethrough with a residuum of elasticity. The printed circuit board consists of an insulative sheet with a plurality of selectively interconnected metallic electrical terminals each having a hole therethrough smaller in diameter than the outside diameter of the electrical lead, but larger in diameter than the wire by a factor of appreciably greater than 2. The method according to the invention comprises stripping the insulation from an end of the lead to provide a predetermined length of wire projecting from the abutment of the insulation formed by the stripping. The wire is then folded to form a narrow J-hook, the folded width of which is appreciably greater than the diameter of the hole. The point of the fold is selected such that the distance between the tip of the wire and the abutment of the insulation is substantially equal to the thickness of the board.

International Classification:

H01L 21/311
H01J 37/32

Abstract:

Methods and apparatus for etching a high aspect ratio feature in a stack on a substrate are provided. The feature may be formed in the process of forming a 3D NAND device. Typically, the stack includes alternating layers of material such as silicon oxide and silicon nitride or silicon oxide and polysilicon. WFis provided in the etch chemistry, which substantially reduces or eliminates problematic sidewall notching. Advantageously, this improvement in sidewall notching does not introduce other tradeoffs such as increased bowing, decreased selectivity, increased capping, or decreased etch rate.
