  • Publication number: 20190252181
    Abstract: A method includes disposing a semiconductor substrate over a chuck. The chuck has a plurality of holes therein. The semiconductor substrate has a first surface facing the chuck and a second surface opposite thereto. A liquid layer is formed flowing over a top surface of the chuck by supplying liquid to the top surface of the chuck through the holes of the chuck. The semiconductor substrate is moved toward the chuck such that the first surface of the semiconductor substrate is in contact with the liquid layer and the liquid layer flows between the first surface of the semiconductor substrate and the top surface of the chuck.

  • Publication number: 20190201065
    Abstract: A method for fabricating a medical device includes steps as follows: A degradable powder including at least one metal element is firstly provided on a target surface. A focused energy light bean is applied to sinter/cure the biodegradable powder within an oxygen-containing atmosphere; wherein the oxygen concentration of the oxygen-containing atmosphere is adjusted to provide a first oxygen concentration and a second concentration when the focused energy light is driven to a first location and second location of the target surface respectively. The aforementioned processes are then repeatedly carried out to form a three-dimensional (3D) structure of the medical device.

  • Publication number: 20190181135
    Abstract: A control circuit providing an output voltage and including an N-type transistor, a first P-type transistor and a second P-type transistor is provided. The N-type transistor is coupled to a first power terminal. The first P-type transistor includes a first source, a first drain, a first gate and a first bulk. The first gate is coupled to a gate of the N-type transistor. The first bulk is coupled to the first source. The second P-type transistor includes a second source, a second drain, a second gate and a second bulk. The second source is coupled to a second power terminal. The second drain and the second bulk are coupled to the first bulk.

  • Patent number: 8335997
    Abstract: A method for sorting menu options in a program menu of an electronic device creates an order parameter, a basic count parameter, and a carry count parameter to each menu option. The basic count parameters, the carry count parameters, and the order parameters are recalculated in response to a user-selected menu option, a user-added menu option, or a user-deleted menu option. The menu options are displayed according to the order parameters.
