.~.~ By or with coating at joint interface of a formed part prior to bonding
DEFINITION
Classification: 65/43
(under subclass 36) Processes directed to coating of the adherent face of at least one part prior to the bonding operation.
(1) Note. Processes of bonding a previously coated part with another part are included herein.
(2) Note. Melting of a self-supporting glass part to the molten state to form a glass coating on the joint interface of one of the parts is considered a coating operation for the purposes of this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS:
60.1+, for a process of coating glass in general combined with a glass working or treating operation and see the notes thereunder for the scope of the term "coating" and related fields of search.
SEE OR SEARCH CLASS 148, Metal Treatment,
240+, for a process for producing a reactive coating on solid metal.
107+, and 455+ for methods for joining plural semiconductor substrates. While Class 65 considers silicon and silicon dioxide glass, and hence takes the melting, shaping or fusion bonding of the same (as well as combined operations whether preparatory or subsequent to the melting, shaping, or fusion bonding step), if the structure formed is identified as having utility for semiconductor electrical devices, placement is proper in Class 438; see the search notes therein.
