Abstract: A method for manufacturing an underfill in a semiconductor chip stack having a cavity 4 between a first surface (2, figure 1) and a second surface (3). The cavity has multiple access 109 and vent 110 holes in at least one of the said surfaces. Viscous filling material (13) is applied through the access hole into the cavity thereby squeezing air or gas through the vent holes. The filler material may comprise of a carrier fluid 16 and filler particles 17, and be applied to the access holes by way of a dispenser tube 14. The filler material occupies the space within the cavity such that it surrounds solder balls 7. Once the filler material fills the cavity between a particular access hole and vent hole the filler material may instead be inserted through said vent hole. The vent holes may also comprise a filter element which restricts the filler particles 17 from exiting the cavity.

Abstract: A desalination system (1) for producing a distillate from a feed liquid comprises: a steam raising device (2) having a liquid section (5) and a steam section (6) which are separated by a membrane system (7); a membrane distillation device (3) having a first steam section (11) and a liquid section (12) which are separated by a wall (14) and having a second steam sec­tion (13) which is separated from the liquid section (12) by a membrane system (15); and a heat exchange device (4) having a first liquid section (21) and a second liquid section (22) , which are separated by a wall (23). The steam raising device (2), the membrane distillation device (3) and the heat exchange de­vice (4) are implemented such that raw liquid fed into the second liquid section (22) of the heat exchanger-boiler device (4) is heated by brine liquid from the liquid section (6) of the steam raising device (2), such that permeate from the steam section (6) of the steam raising device (2) is condensed in the first steam section (11) of the membrane distillation device (3), thereby heating heated feed liquid from the heat exchange device (4). A method for operating a desalination system is also disclosed. Advantageously the desalination system operates at a reduced total thermal energy consumption.
