An etching gas composition includes a first organofluorine compound having 3 to 6 carbon atoms, and an organosulfur compound having 1 to 4 sulfur atoms. The organosulfur compound may include a carbon-fluorine (C—F) bond, a carbon-sulfur (C—S) bond, at least one carbon-carbon double (—C═C—) bond. When the etching gas composition is used, excellent etch selectivity may be obtained, and the linearity and verticality of a pattern may be greatly increased by improving line edge roughness (LER) and line width roughness (LWR) due to an improvement in the roughness of an etched surface.

Provided are a message reception notifying method, system, and non-transitory computer-readable recording medium. A message reception notifying method includes predefining a plurality of message types for classifying a message and frames of a notification window for the respective message types; parsing a message received at a user terminal, and determining a type of the received message among the plurality of message types; determining a frame corresponding to the type of the received message among the frames; and creating and providing a notification window for the received message by processing the received message based on the determined frame.

Method, system, and recording medium for notifying reception of message

Provided is a method including providing a text creation interface in response to an execution of a text application; receiving an input signal for selecting content during a text creation process using the text creation interface; uploading the selected content to a cloud storage; and transmitting a text message including route information about a route accessible to the uploaded content to a counter party terminal. If a file capacity of the selected content is greater than or equal to a reference capacity, the selected content is uploaded to the cloud storage in response to a user request and the route information is automatically created and included in the text message.

Method and system for transmitting text messages

Provided are a method, system, and non-transitory computer-readable recording medium for providing a message based on a group unit. A message providing method includes classifying a message received at a user terminal into a predefined group; creating a representative item of the group using a message included in the group; and providing message items through a message list in message box that includes the message received at the user terminal by including the representative item as an item associated with the group and by grouping messages included in the group in the message list.

Method, system, and recording medium for providing message based on group unit

Provided are a method, system, and non-transitory computer-readable medium for managing a group message. A message management method includes transmitting a group message in which a plurality of recipients are set at a terminal of a user; creating a group chatroom that includes the group message; receiving an individual message from a terminal of at least one recipient among the plurality of recipients; including the individual message in an individual chatroom that is created in association with each of the plurality of recipients; and displaying and providing the group chatroom and the individual chatroom as a bundled item.
