HSMS is a protocol designed to facilitate the reliable transmission of messages between semiconductor equipment over TCP/IP.

Most commonly, exchanged messages are encoded with the SECS-II (SEMI E5) protocol.

For ease of programming and extension, the functionality of the protocol has been divided into a few subsets:

• Primitive Services - Manages the TCP/IP connection and the sending of messages with proper headers.
• Generic Services - Manages the sending of messages of particular types and at particular times as allowed by the protocol.
• Single Selected Session Services - Manages the restriction of the protocol to scenarios involving a single host/equipment pair in communication.
  • Not yet implemented.
