I recently design a project on Arduino Micro. I had found that the project was small enough to mount on a atTiny45.
Now when i setup my arduino as an ISP, and try to burn a boot loader to the atTiny45-20pu i get a message that i have an incorrect device sigature.
How can i resolve this problem?
Disable auto-boot on the Arduino running ArduinoISP. I use a 1 to 10 uF capacitor between Reset (+) and Ground (-).
i have done that now i get this error:
avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
0xdf != 0xff
avrdude: verification error; content mismatch
avrdude: Send: Q [51] [20]
avrdude: Recv: . [14]
avrdude: Recv: . [10]
avrdude done. Thank you.
Please Help

Pity that You dont have any other ISP programmer that could work with Atmel Studio.
I am working on project with Attiny 25 20PU and when i started i found out that some of my Attinys were bricked up from past when i had absoultely no idea how to program and so.
So to test if the atmel is ok, i am using ZeptoProg programmer which works with Atmel Studio and there, if You can read device infos, the chip itself is okay. Then You must work around with the wiring.
The previously mentioned capacitor is must have, at least for me, without it, the upload did not work.
I had 100uF so i used that one instead of 10uF.
How do You upload it? I am using "Upload Using Programmer Ctrl+Shift+U" option from "File" menu.
Dont forget to specify COM port where the Arduino as ISP is connected and also that You are using Arduino as ISP 
This is how my setup looks.
Pin 2 is my heartbeat
Pin 3 is my Error
Pin 4 Is my Programming
Pin 8 is Mosi
Pin 9 is Miso
Pin 10 is Reset
Pin 11 is SCK
I had changed these pins in the pins.h. it comes from a forum that i had read.
Also I am using the Arduino as ISP Example with the pins formatted for the Heartbeat, Error, Programing.
The Current Cap i have installed is a 1uF i have also tried 100uF and 10uF.
Have already tried upload using all the upload options. non of them work.
Also i had this problem since i had purchased the tiny45s.
