Hi Mukesh,

Yes, you can achieve this functionality by using a trigger. You can use the trigger on sobject you want
to insert an attachment at creation time. In the Below Code, I have use Account as sobject and create a
new text attachment at the time of the creation of account.

And if you want to upload any file then the file should be in your org. You have first upload the file in
documents ----> select any folder you want to upload file ---> then query the file to insert to attachment.

Trigger ==>>> 
trigger InsertAttachmentAtRecordCreationTime on Account (after insert) {
    if(trigger.isAfter && trigger.isInsert){
        InsertAttachmentAtRecordCreationTime.insertAccount(trigger.new);
    }
}
Handler Class ==>> 
public class InsertAttachmentAtRecordCreationTime {
    public static void insertAccount(List<Account> aclist){
        try{
            List<Attachment>  Attachment_List = new List<Attachment>();
            for(Account ac : aclist){
                Attachment attach = new Attachment();
                attach.Name = String.valueOf('test.txt');
                attach.body = Blob.valueOf('You can give any String Value');
                attach.parentId = ac.Id;
                Attachment_List.add(attach);      
            }
            insert Attachment_List;
        }
        catch(Exception e){
            System.debug('Line No:-->'+e.getLineNumber()+' '+'Error---->'+e.getMessage());
        }
    }
}
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
