A vapor deposition apparatus includes a deposition chamber, an umbrella-shaped supporting member, a plurality of coating precursor sources. The umbrella-shaped supporting member is received in the deposition chamber. The supporting member is configured for supporting a number of workpieces. The coating precursor sources oppose the supporting member. Each coating precursor source includes a stationary sleeve and a moveable member moveably received in the stationary sleeve. The moveable member defines a recess for receiving a coating material in a top end of the moveable member opposing the supporting member. The moveable members are moveable relative to the respective stationary sleeve such that a distance between the supporting member and the coating material in each recess can be adjusted.
