Plunger (10) for brewing a drink in a cup (12) includes two main components, a filter disc (20) and a frame (22). The filter disc (20) is shaped to extend across and abut an inside surface (24) of the cup (12). The frame (22) is dimensioned so that it can be wholly inserted into the cup (12) to be disposed below a mouth (18) of the cup. This allows a drink such as coffee or tea to be brewed in the cup from which it is to be consumed without the plunger (10) interfering with the drinking of the drink. The disc (20) is supported on the frame (22) to slide along upright posts (22). Thus the disc (20) can be pushed toward the bottom or (14) of the cup (12) that contain particulate materials such as coffee grounds or tea leaves used in brewing the drink. A heat shield (58) may be also supported on the frame (22) to minimise the rate of heat loss of a hot drink brewed in the cup (12) using the plunger (10).

A crystalline semiconductor film in which the position and the size of crystal grains are controlled is provided, and a TFT that can operate at high speed is obtained by forming a channel formation region of the TFT from the crystalline semiconductor film. A heat retaining film is formed on an insulating surface, a semiconductor film is formed to cover the heat retaining film, and a reflective film is formed to partially cover the semiconductor film. The reflective films and the semiconductor film are irradiated with a laser beam. The reflective film creates a distribution in effective irradiation intensity of laser beam on the semiconductor film. The distribution, with the heat retaining effect provided by the heat retaining film, generates a temperature gradient in the semiconductor film. Utilizing these, the position where crystal nuclei are to be generated and the direction in which crystal growth should advance can be controlled and crystal grains having a large grain size can be obtained.
