摘要： A method for forming semiconductor devices involves nebulizing a liquid suspension of particles to form tiny droplets of particles and liquid which are well separated from one another. The nebulized droplets may correspond roughly to the average particle size which may be, for example, about one to two microns. The particles in droplet form then form a vaporous dispersion which can be dried to remove the liquid. The particles may be biased so as to repel one another to further form a well defined separation between adjacent particles. The particles may then be collected on a substrate so that a random distribution of masking particles are formed. The randomly distributed particles may be used as a mask for defining features in a semiconductor structure. The mask may be utilized, for example, to define emitters in a field emission display or spacers in a liquid crystal display.

摘要： Provided is an apparatus and method for protecting against unsafe electric current conditions. A protections circuit may be used in a device, such as an electric grill, that has one or more electric loads, such as heating elements. The protection circuit may protect against various failure scenarios, including, without limitation, instances of ground fault, over current, driver failure, and failure of a microprocessor. In response to a failure, the protection circuit may trip a latch relay or disable a triac driver to stop current from flowing.

摘要： A method for forming an etch mask is described. In particular, an etch mask is formed using masking particles positionally restrained by a matrix medium. Either the masking particles or the matrix medium is more magnetically conductive with respect to the other. A magnetic field is applied for making a random distribution of the masking particles less random. Consequently, agglomeration of the masking particles is reduced. Masking particles with submicron dimensions may be used for providing features of less than a micron. The mask formed may be an etch mask employed in forming a field emitter tip for a field emission display.
摘要翻译：描述了形成蚀刻掩模的方法。特别地，使用由基质介质位置约束的掩模颗粒形成蚀刻掩模。掩模颗粒或基质介质相对于另一个更具有导磁性。施加磁场以使掩蔽粒子的随机分布更少随机。因此，掩蔽颗粒的团聚减少。具有亚微米尺寸的掩模颗粒可用于提供小于一微米的特征。形成的掩模可以是用于形成用于场致发射显示的场发射器尖端的蚀刻掩模。

摘要： Provided is an apparatus and method for protecting against unsafe electric current conditions. A protections circuit may be used in a device, such as an electric grill, that has one or more electric loads, such as heating elements. The protection circuit may protect against various failure scenarios, including, without limitation, instances of ground fault, over current, driver failure, and failure of a microprocessor. The microprocessor may further be in wireless communication with a remote device and wirelessly communicate error codes indicative of an error, and receive control signals from the remote device for controlling temperature or turning the grill off. The remote device may also receive operating parameters and create a log of the electric grill's conditions at the time of an error.
