Letter ballots are periodically issued by SEMI Standards. The letter ballot is the first step in the approval process required for publication of a new or revised standard.
Cycle 05-19 is now closed. However, some committees still need more votes.
Informational ballots are use to receive comments and refine a standards draft document prior to being issued as a Letter Ballot.
