Abstract: A method for forming indicia on a semiconductor device package, such as laser marked or ink stamp marked indicia. The method can be performed on an apparatus, such as a production apparatus, which forms the indicia as well as performs semiconductor device trim and form operations. An embodiment of the present teachings ensures that the indicia marking process at a laser marking station does not occur simultaneously with the device trim and form operations at a trim and form station. Trim and form operations, particularly using a ram press, can impose vibrations on the laser marking station. Ensuring that laser marking does not occur simultaneously with trim and form operations removes the negative effects of vibration on the laser marking station.

Abstract: A device is intended to measure an absorbed dose of a hazardous gas by skin of a human body and is composed of an exposure chamber, a gas concentration control system, and one or more gas sensors. A naked part of the human body is held in the exposure chamber containing the hazardous gas of a concentration which is kept in a predetermined range by the gas concentration control system. As the concentration of the hazardous gas drops below the predetermined range, the gas concentration control system replenishes the exposure chamber with an amount of the hazardous gas with the help of a concentration signal transmitted from the sensors, so that the concentration of the hazardous gas is once again kept in the predetermined range. The absorbed dose of the hazardous gas by skin is computed on the basis of the amount of the hazardous gas that is replenished.
